What are square numbers? The product of a number times itself is a square number. For example, 3 x 3 = 9, so 9 is a square number. Square numbers can also be described as the area of a square with side lengths that are natural numbers. Below is a list of square numbers. All math students should memorize the squares through 400, and be somewhat familiar with the rest of the squares on the list. Familiarity with square numbers is very useful in algebra and other higher math classes.
REMEMBER: All students should email me if they have any questions about the assignment, how to do their homework, or if they are struggling with a particular problem. Be sure to include your name and which class you are in when you email.
Here’s the homework for this week:
Foundations in Math
Most important thing to do this week: Be sure you have signed up for our class on Quizlet. The link and code were emailed. Let me know if you would like them emailed again. A few students have not yet joined our class on Quizlet. They are missing out on lots of important practice which is most of the homework for this class!
Check out Educreations and Quizlet for new practice.
We’ve finished with addition and subtraction facts. We’ll continue to mentally add and subtract larger numbers as we move into multiplication and division.
In your 3-ring binder, there are some pages to complete. I will note the titles of the lessons I want you to complete. Keep in mind the page numbers have nothing to do with the order of the pages are in your binder.
Complete some lessons in your binder. After the blue tab, finish the lesson titled “Mental Subtraction, Part 2”. It’s page 72. After the clear tab, finish the lesson titled “Multiplication Table of 5”. Remember, each 10 is two 5’s.
Continue to add and subtract two digit numbers mentally using the strategies we’ve learned. For individual practice, or as a game, roll two pairs of dice. Use each pair to form a two-digit number. Add the numbers, then subtract the numbers.
Continue memorizing the square numbers through 400. The goal is to know all of these by the end of the semester. Here they are, plus a few extra:
In each lesson, be sure to aim for accuracy, then speed. Read the directions and try to think about the problems as the lesson asks you to. Also, when answering a work problem or story problem be sure to write the expression or equation you solved to find the answer.
Math for the Middle Grades – Daily work as listed on the blue sheet in your student’s binder: Complete lessons 32-34. Parents, please score your student’s work each day, even if the student has not completed the lesson. Students, correct any errors and email me if you need help.
Homework as listed on the yellow sheet in your student’s binder: Complete homework number 11. Look in the homework section (“H”) in your binder and find the sheet or sheets marked “11”. Do not score Homework. Hand it in unscored.
Math 76 – Lessons 41-42, and Test 6. We did the practice problems for these lessons in class. Complete the odd-numbered problems in the problems set for each lesson. Score your work as shown in class, and as described in one of your handouts. Score keys were distributed in class. Take the time to rework previously finished tests. See handouts in your binder to find out how. Be sure to email for help with any problem, even test problems.
Algebra 1/2 – Lesson 41-45. We did the practice problems in class. Complete the odd-numbered problems in the problem set for each lesson. Be sure to check on previous tests and rework if necessary.
Algebra 1 – Lessons 46-50 and Test 8. We did the practice problems in class. Complete the odd-numbered problems in the problem set for each lesson.
Algebra 2 – Lessons 46-50 and Test 8. We did the practice problems in class. Complete the odd-numbered problems in the problem set for each lesson. Videos for lesson 50 will be sent out shortly. For lesson 50, do not complete the odds. Complete any completing the square problems in the video. That’s the only work assigned for lesson 50.
Unit 6, sections 1 and 2. Do all non-proof problems and all even-numbered proofs. The remaining proofs are optional.

11/22 no class
11/29 proof of Theorem 3-17, Unit 3, page 65
12/6 proof of Theorem 4-5, Unit 4, pages 34-35
12/13 proof of Theorem 5-1, Unit 5, pages 21-22
Corollary 1 to Theorem 5-1
Corollary 2 to Theorem 5-1
