String Activity Discuss in small groups: –What was the purpose of this activity? –What did we learn about our students?

Art Class Task Complete task independently Read the scoring guide In small groups review student work and score their work and compare the scoring that was done. How would this activity help students make sense of area?

Break

Measurement Concepts with Tangrams Work on handout with small group What are the mathematical concepts being developed? How would this activity help students make sense of area?

Triangle Areas Make as many different triangles with 6 square units on your 10 x 10 dot grid paper. If you were not restricted to the 10 x 10 grid, what is the largest perimeter possible?

Lunch

Angle Measurement Activity Look at the two angles. Which angle is larger? Independently answer these questions: –What is an angle? –What does it mean for a triangle to have 180˚? –What does it mean for a four sided figure to have 360 ̊ ? –What does it mean to say a line has 180 ̊ ? –What does it mean to say a circle has 360 ̊ ? What is the purpose of this activity?
