AIM: How can we decide whether a situation about a circle requires area or circumference?
Announcements: The NYS Math Assessment for 7th Grade will be May 4-6. Please begin your preparations now.
HW: 1. Test Reflections 2. Goat Problem Below 3. Schoology Probability and Statistics Assignment
About how many cheese puffs can fit on the plate in a single layer? Be prepared to explain your reasoning.
Students were presented with a variety of circle situations. They sorted cards into categories of "area" or "circumference" problems. From there, partnerships were randomly assigned a problem in which they estimated values to base their circle calculations on. We finished the lesson with an activity that allowed students to critique the responses made by two students on three mock problems. Good mathematical discussion ensued.
THE GOAT PROBLEM
A goat (point ) is tied with a 6-foot rope to the corner of a shed. The floor of the shed is a square whose sides are each 3 feet long. The shed is closed and the goat can't go inside. The space all around the shed is flat, grassy, and the goat can't reach any other structures or objects. What is the area over which the goat can roam?
