Homework and Announcements
12/9/2019
Happy Monday! We have a big week ahead of us. All classes are wrapping up the unit that they are currently working on at some point this week. Read below to see how best to prepare:
Math 6 This week, we are finishing our mini-unit on percentages. We went out of the text book for this unit as I have found in past years that our text doesn't quite dive deep enough into percentages. You will be receiving a review sheet on Wednesday and the test will be on Thursday. Your only homework is MathXL and the review sheet if you don't finish it in class on Wednesday. Math 6 - Topics Covered this week Let’s say 440 people attended a school fundraiser last year. If 330 people were adults, what percentage of people were adults? If it’s expected that the attendance this year will be 125% of last year, how many attendees are expected this year? A double number line can be used to reason about these questions. Students use their understanding of “rates per 1” to find percentages, which we can think of as “rates per 100.” Double number lines and tables continue to support their thinking. The example about attendees of a fundraiser could also be organized in a table. Toward the end of the unit, students develop more sophisticated strategies for finding percentages. For example, you can find 125% of 440 attendees by computing With practice, students will use these more efficient strategies and understand why they work. Here is a task to try with your student: For each question, explain your reasoning. If you get stuck, try creating a table or double number line for the situation.
Solution: Any correct reasoning that a student understands and can explain is acceptable. Sample reasoning:

The test is shorter than usual, so I am only setting aside one day to complete it. Your only homework is MathXL and the review sheet if you don't finish it in class. Math 7 - Topics Covered this week This week your student will work with graphs that represent proportional relationships. For example, you could make a graph that represents a relationship between the amount of square feet of carpet purchased and the cost in dollars. Say for instance that each square foot of carpet costs $1.50. The point on the graph tells us that 10 square feet of carpet cost $15. In proportional relationships, the points on the graph are arranged in a straight line. If you buy 0 square feet of carpet, it would cost $0. Graphs of proportional relationships are always parts of straight lines including the point (0,0). Here is a task to try with your student: Create a graph that represents the relationship between the amounts of grape juice and peach juice in different-sized batches of fruit juice using the recipe “for every 5 cups of grape juice, mix in 2 cups of peach juice.” (source: Open Up Resources) Comments are closed.
