Homework Wed. 11/29

Today we worked on the second and last packet of problems on solving linear equations. Do handouts marked pg. A-46, A-47, and A-48. Due to the length of time to solve these, you have the option to work through all and answer the puzzle, but are required to only do half of each page. There will be an assessment on this topic this next Tuesday.

Homework Mon. 11/27

Today we continued work from the previous class on the handout packet pg. A-39, 40, 41, and 44. We will get the last group of multiple step equations on Wednesday to complete by next weeks test.

In class Mon. 11/20

Today we began a section on solving linear equations. This will appear in the textbook in Unit 3, but is necessary to know in the current form now. In class today we worked on the Handout pg. A-39, single step equations. On Monday 11/27 we will continue onto pg. A-40, A-41 and A-44.
To solve linear equations:

1. Simplify on each side of the equal sign.


2. Combine Like Terms (like terms are those that contain the same variable or group of variables raised to the same exponent)


3. "Undo" any addition or subtraction operations to the variable


4. "Undo" any multiplication or division operations to the variable

In Class Thurs. 11/16

Test Today
Todays work will be the test over Unit 2, lessons 1 to 3.
Be prepared to write equations as rules and use these equations to solve problems.

Homework Tues. 11/14

Todays work is pg. 132-134, #1, 2, 4 and pg. 137, #4 (skip 4e).
For a challenge, instead try pg. 132, #1, pg. 137 #4 (all) and pg. 139, #1, 2, and 4.
You should then prepare for the quiz on Thursday over Lessons 1, 2, and 3. Be able to describe a pattern from a table (As x changes _____, y changes _____). Be able to read or plot on an x-y axis graph or scatterplot. Identify rates of change from a table or graph. Write equations in NEXT=NOW format or y = a + bx format. Find the % of a number.

In Class and Homework Thurs. 11/9

Today we worked to finish the Palace Theater problem on pg. 122-124, #5, 6, and 7. We also worked with writing equations, creating and using tables and graphs to answer questions on pg. 126-128, # 1, 2, 3, and 4.

Homework Tues. 11/7

Todays homework is to finish pg. 122, # 1, 2, 3, 5, and 6. No graphs, just tables, equations and answer questions. We will produce graphs using the graphing calculators next class, to finish the Palace Theater question. In class we used the calculator to do iterative or recursive changes (each term is generated by repeating math operations), we wrote equations in Next=Now form, and we summarized patterns relating variables using rules.

Homework Fri. 11/3

Todays homework is pg. 111-112, # 1, 2, 3, and 4. In class we focused on patterns of change in variables and explored repeating patterns. We were able to write equations in NEXT=NOW form, to investigate population growth over time in Brazil and the U.S.

In Class 11/1

Today we worked on completing pg. 105, #1 using the calculator to produce boxplots and scatterplots to answer the questions and look for patterns and trends. Using a calculator, we used height and weight data to produce a scatterplot, then did a linear regression [Stat]- [Calc]- [LinReg(a+bx)] to produce a best fit line in the form of y = a + bx. After graphic the scatterplot with the line, we created a table [2nd]-[Table] to examine the data and make predictions using the equation as a model. To rapidly move around a table, on your calculator, use [2nd]-[TblSet] to set up the starting x-value [TblStart= ] in the table and [change Tbl= ] to change the x-value increment amount.
