Ratios, Pet Survey, and ACE 1.2 Targeting an Audience

Today we did more work with ratios, as well as fractions, percents, and differences. Groups compared their results on their ACE homework, and we had a few more presentations of Stretching and Shrinking unit projects.

The small group started working on additional practice problem looking at ratios and comparisons with number of years spent doing different activities during your lifetime.

The large group worked on problem 1.2, deciding whether or not statements accurately reflected survey results, and judging whether the statement was effective or informative. Class notes for the large group can be downloaded here.

Both small and large groups in both classes participated in Pet Surveys.
7A had 15 cats, 7 dogs, 0 hamsters, 10 birds, 5 fish, and 1 snake/lizard/turtle.
7B had 7 cats, 7 dogs, 0 hamsters, 10 birds, 38 fish, and 1 snake/lizard/turtle.

Homework for both small and large groups is to complete the handout, which you can download here.
