Students will be able to divide circles and rectangles into halves.
Language
Students will identify and describe halves as equal parts using content-specific vocabulary with sentence frame support.
Introduction
(3 minutes)
Gather students on the rug and draw a large circle on the board.
Say something like, "Every Friday I invite my friend over for pizza. She loves pineapple on her pizza. I think that's weird. I only like anchovies on my pizza."
Shade one fourth of the circle. Tell students, "My friend thinks that the amount I just shaded, or colored in, should have anchovies, and the rest should be pineapple. What do you think?"
Discuss with students that your friend is not being fair. The amount of each type of pizza is not equal.
