Monday Oct 20: we started with the 'false fraction simplification' challenge question from last week. Then we went through lesson 3.4.and did pages 27-31 of the Square Roots Notes Booklet. The assignment for this section is still textbook page 18 #4-7, 9-13, 17,19,22, so if you didn't finish that over the weekend, you have one more night to get that done. We will do our test on this chapter on Thursday.
Friday Oct 17: Trans Math Test #2 - Squares, Square Roots and Pythagoras. After you finish, you can work on textbook page 18 #4-7, 9-13, 17,19,22 - these should be done for Monday. If you are done that, you can go back to this fraction decimal percent practice page that I handed out after our last test, OR you can work on this Waterloo Math Contest problems handout. Here is the answer key for that.
Thursday Oct 16: we went over some of the textbook page 11 questions and the two challenge questions I left you with on Tuesday and yesterday, then I gave the class two more challenge questions that have to do with squaring, exponents, and pythagoras. We'll look at the answers to those next week. The rest of the class was time to work on either textbook page 18 #4-7, 9-13, 17,19,22 or the (optional) practice worksheets for Friday's Trans Math Test, with this sheet on the front and this sheet on the back or this practice quiz on estimating square roots. The files linked here have answer keys.
Wednesday Oct 15: after finishing up a quick note on page 17 (and answering one of yesterday's challenge problems) we went through the notes and examples for pages 21,22,24, and 25 of the Square Roots Notes Booklet. The textbook assignment for this lesson is textbook page 11 #3,5,7-12 (omit 12b),14-18 and page 18 #4-7, 9-13, 17,19,22. I gave the class time to work on this and the page 11 questions should be done for tomorrow. You can have more work time on Thursday and Friday to finish the page 18 questions and they will be due for Monday. I have another challenge question for you: can you think of a repeating decimal that is a perfect square? For more (optional) practice for Friday's Trans Test, I handed out this practice quiz on estimating square roots. The file here has its own answer key
Tueday Oct 14: We started class by refreshing our memories on how to simplify fractions (like we did on page 20 last week) and how to convert decimals to fractions, then we combined those skills by doing page 23 in the Square Roots Notes Booklet as a warm up (we ignored the instruction to NOT simplify - that would have been insane! - and for #25-36 we switched them to improper fractions). Then we finished correcting this page on the back (here is the answer key so you can check yours at home if you missed today's class). Then we went back to pages 17 and 18 and filled in these blank pages with some notes and examples to remind us how to square fractions and decimals. No new homework yet, but I left the class with two challenge questions: the famous 'false fraction simplification' problem and 'Does a perfect square have to be a whole number'? I also handed out one more (optional) practice worksheet for Friday's Trans Math Test, with this sheet on the front and this sheet on the back. The files linked here have answer keys. Speaking of challenging questions, some of you already have this Waterloo Math Contest problems handout. Here is the answer key for those of you who have already been working on it.
Friday Oct 10: we started by finishing our discussion of why the fractional square root calculations we are doing are only estimates and not exact values. Then we did page 20 of the Square Roots Notes Booklet as a warm up. Then we corrected the worksheet with this page on the front and started going over this page on the back (here is the answer key so you can check yours at home if you missed today's class). If you aren't finished this page, that is your only homework for the weekend. Next week Friday we'll do our second Trans Math Test on square roots of whole numbers and pythagoras calculations.
Thursday Oct 9: we started class with some work time for Examples 3 to 6 on pages 14-16 of the Square Roots Notes Booklet. Then we discussed the "challenge" question I asked you yesterday - which was basically to explain why the fractional square root estimation technique we have been using is, in fact, only an approximation of the true value of the square root of a non-perfect square. Then we started lesson 3.3: Square Roots of Rational Numbers. We went through pages 19 and 21 together. Your homework is to finish Example 5 on page 22 and if you are not done the worksheet with this page on the front and this page on the back (here is the answer key), then do that. We will be back to using our textbooks tomorrow.
Wednesday Oct 8: We went over the two "classic" pythagoras problems from Monday, then we watched this video to confirm the result of the 2nd of those problems. Then we did some more explanation and demonstration for estimating square roots using benchmarks on a number line. I gave the class a few minutes to work and then we corrected Examples 3 to 6 on pages 14-16 of the Square Roots Notes Booklet. I'll give you another 30 minutes of work time tomorrow. I left the class with a challenge question to think about for tomorrow. Then, for extra practice, I handed out a worksheet with this page on the front and this page on the back. The rest of the class was to finish up the worksheet - here is the answer key.
Tuesday Oct 7: we corrected page 7 in the Square Roots Notes Booklet together. Then we had time to work on this Pythagoras Review Sheet. If you don't finish it in class time, it will be homework. Recall that I gave you the two "classic" pythagoras problems from yesterday. We'll go over them tomorrow. After that, we moved on to Lesson 3.2: Estimating Square Roots of Whole Numbers, covering pages 11-13. Your assignment for this lesson is to finish Examples 3 to 6 on pages 14-16. I'll give you a few minutes of class time to finish those tomorrow.
Monday Oct 6: I handed out our new notes booklet: Square Roots Notes. We went through pages 3-6,8 and 9 together. We also spent some time reviewing the Pythagorean Theorem. We watched this video, and this video, and this video and this video (this is the Vi Hart one) . The assignment for this lesson is to fill in the "Example 1" chart on page 4 and do the "Example 4" questions on page 7 and this Pythagoras Review Sheet (the file link has an answser key for you to check your answers). Then to end the class we used the blank page 10 to do a couple of interesting (classic!) problems that involve the Pythagorean Theorem. We will go over them tomorrow.
Friday Oct 3: Powers and Exponents Test. If you finish with time to spare, I handed out this fraction decimal percent practice page. We will start our next unit reviewed some skills you learned in grades 6-8 that allow you to convert fractions and decimals from one to another. The worksheet copy linked here has an answer key if you can't wait for next week to check if you are correct.
Thursday Oct 2: we went over some textbook page 84 questions. Then we had time to work on the Practice #3 (here is the answer key), and Practice #4 (here is the answer key) worksheets that I handed out yesterday. If you finish those and you still feel as though you need more review before the Chapter 2 test tomorrow, you can work on the review on textbook pages 87-89 and the practice test on page 90.
Wednesday Oct 1: we went over the Practice #2 sheet and I gave the class a little more time to work on textbook page 84 #4-9, 11,12,14,15,16,19-21 it should be done for tomorrow. For people ready to move on, I handed out Practice #3, and Practice #4 worksheets. If you finish those and you still feel as though you need more review before the Chapter 2 test, you can work on the review on textbook pages 87-89 and the practice test on page 90. We'll write the Chapter 2 test on Friday. I'll let you have some review/work time tomorrow after we go over the page 85 questions.
Tuesday Sept 30: No school today - Truth and Reconciliation Day
Monday Sept 29: we corrected the Practice #1 sheet and then we went through the examples on pages 20-22 of the Powers and Exponents Notes booklet, then the class had some time to work on textbook page 84 #4-9, 11,12,14,15,16,19-21. You should be done that for Thursday. For Wednesday, make sure you are done the Practice #2 sheet that I handed out on Friday of last week. We will test the Unit THIS Friday.
Friday Sept 26: we lose this period to the Truth and Reconciliation Day activities. Have a great weekend!
Thursday Sept 25: we went over some of the textbook page 76 problems. Then we went through the "quick practice" questions from page 19 of the Powers and Exponents Notes booklet. Then we ended the class by looking at the sheet called Practice #1 (which I handed out back on Monday), which reviews the first lesson of this chapter - this is the first step in getting ready for a test next week! I also handed out the Practice #2 sheet today. Have the Practice #1 and Practice #2 sheets done for Monday.
Wednesday Sept 24: we had some time to work on textbook page 76 #4-8, 10,11,13,15,20-23. Then we went through the exponent laws 2 lesson on pages 14-16 of the Powers and Exponents Notes booklet. Your homework for tomorrow is to finish up the textbook page 76 assignment. You also have a sheet called Practice #1 on Monday that you could work on.
Tuesday Sept 23: we went over some of the textbook page 66 questions together. Then we did a few examples in our notebook to fresh our memories on the first three power laws. We first met those on pages 8-10 of the Powers and Exponents Notes booklet, which we did in class last week. The Practice #1 sheet that I handed out after yesterday's test should be done for tomorrow. If you are done, you can move on to the new assignment, which is textbook page 76 #4-8, 10,11,13,15,20-23. I'll give you a little work time tomorrow for that.
Monday Sept 22: we started by quickly correcting the practice riddle that I handed out on Friday, then we went back to the BEDMAS puzzles I handed out back on our first day of classes a couple of weeks ago (here, at long last, is the answer key). After that, we did Trans Test #1: BEDMAS. People who finished with class time to spare were free to work on this sheet called Practice #1, which reviews the first lesson of the Powers and Exponents chapter. Reminder that the textbook page 66 assignment from last week should be done. We'll go over that tomorrow.
Friday Sept 19: after some work time, we corrected the BEDMAS practice sheet sheet together (if you missed class today, correct it yourself with this answer key). Then we solved the 7^99 problem from yesterday. We ended by looking at a math meme that keeps floating around the internet. For homework this weekend to get more ready for the first Trans Math test on Monday (on BEDMAS) here is another practice riddle (the file here has an answer key at the end). Also, if you still need to finish up textbook page 66 #3-5,10,11,14,15,16,18,20,21,22,24,26,27, please have that done for Monday.
Thursday Sept 18: we went over some of the textbook page 66 questions together and had some time to work on finishing that assignment. Then we worked on this BEDMAS practice sheet. We will do our first little test of the year on this material (for our Trans Math credit) this Monday. After that, we got back into thinking about Powers and Exponents by going back to a question I left you with last week: is 8^x always going to be larger than 9^x-1? To solve that I showed the class how to use Excel. Then I left you with a new problem. What will the ones digit of 7^99 be?
Wednesday Sept 17: I started class with a story about why 13 532 385 396 179 is my favourite number. Then we had with time to work on textbook page 66 #3-5,10,11,14,15,16,18,20,21,22,24,26,27 (for #16, just get the answer, you don't need to write out the button sequence). I'll give you a few more minutes to work on this assignment tomorrow. If anyone does finish that with time to spare, here is a trans BEDMAS practice sheet to work on. Here is the answer key If you finish it tonight and want to check your answers. We'll wrap up our Trans Math BEDMAS review tomorrow by going over the BEDMAS puzzles I handed out back on our first day of classes a couple of weeks ago.
Tuesday Sept 16: we added BEDMAS rules to our review of basic integer calculation rules and I handed out this spooky bedmas riddle as our drill for this class. Then we went back to the Powers and Exponents Notes booklet and did the notes for page 12. Then we did the evalute questions on page 13 and corrected them. You can start on the next homework assignment tonight, textbook page 66 #3-5,10,11,14,15,16,18,20,21,22,24,26,27. I'll give you time to work on that one tomorrow.
Monday Sept 15: We started with a quick review of our integer calculation rules. Then I handed out this Adding, Subtracting, Multiplying, and Dividing Integers worksheet and we did it as a drill to see where we might need to freshen up these skills. Then it was back to our Powers and Exponents chapter, where we went over we went over some of the textbook page 61 and the scientific notation practice sheet questions together. Then we went through the next lesson in the Powers and Exponents Notes booklet, pages 10-11. No new homework tonight.
Friday Sept 12: we started with this Negative Base Practice warm up. Then we went back to the Powers and Exponents Notes booklet and did the examples on pages 7-9. After that we had time to work on our next assignment, textbook page 61 #4-11, 14. People ready to move on from the page 61 assignment can finish up working on the scientific notation practice sheet that I handed out yesterday. Both the textbook assignment and the sceintific notation practice sheet should be done for Monday.
Thursday Sept 11: We corrected #3 from the Powers of Negative Bases Practice sheet that we did yesterday. Then we did the back of that page and corrected it. Then we went over some of the textbook page 55 questions together. Towards the end of the period we looked at using scientific notation for really big numbers. I handed out this practice sheet (the file here has the answer key) for people to work on It should be completed for Monday.
Wednesday Sept 10: we started with our first textbook assignment for this year, textbook page 55 #4,5,7-9,11,13,16-18,20,21,24. We will go over them tomorrow, so if you don't finish these in class, you have some homework to do tonight. Anyone who might already be finished should try finishing the BEDMAS puzzles I handed out last week (can anyone get 39 without using a square root?). At the end of the class, I handed out this Powers of Negative Bases Practice sheet that we did in class as a little practice speed test and then we went over the first two questions together. We'll go over #3 tomorrow and save the back for the end of tomorrow's class. If you missed class today, you can download it and try it yourself (the file link has an answer key at the end of the file).
Tuesday Sept 9: we went through page 4 and then had time to finish up the "Quick Practice" questions on pages 5,6 of the Powers and Exponents Notes booklet. Then we looked at a couple of fun facts about exponents. We discussed Al's Allowance and the Legend of Pal Paysam. For tomorrow's class, please bring your textbook.
Monday Sept 8: After looking over some student answers, I gave the class some hints with the BEDMAS puzzles that I handed out on Friday. We'll re-visit them again later in the week. Then we wrapped up the 24 game that we were playing on Friday. We used that as a spring board to start talking about EXPONENTS. I handed out the Powers and Exponents Notes booklet. We did the notes together for pages #1-3. We'll finish up page 4 tomorrow. If you want to try to work ahead, the assignment for this lesson is the "Quick Practice" questions on pages 5,6. You can try them for homework tonight, but if you don't finish them, I'll give you a few minutes to finish this up tomorrow.
Friday Sept 5: we continued going over the course outline from yesterday and discussed the expectations that I have for you going forward. Then we wrapped up the little number game that we started yesterday with the 3-digit numbers on your textbooks, and finally, we moved on to one of my favourite number games: the 24 game. The goal of the 24 game is to have a fun way to work on basic arithmetic operational skills, especially brackets. So for a little bit of homework over the weekend, I am handing out these BEDMAS puzzles for you to try. Play with them for a few minutes this weekend and see how many you can get. On Monday, I'll give you some examples to help you solve them all.
Thursday September 4: Welcome to Grade 9 Math! Nothing too strenuous on the first day! We went over some of the course outline, I assigned textbooks and we played with the numbers on the textbooks a little. For fun, see if you can find the "constant" for a 4-digit number. See you tomorrow!
