  1. 3-5-13 Review of 2 Dimensional Shapes EQ: How do you find area and perimeter of 2D shapes? How does changing dimensions affect the area of a two dimensional figure? What are scale drawings? BOP AND DWP Continue working on review handout for 2D Shapes.

  2. Present Graphic Organizers completed on Monday. Go over problems 1-7 on Study guide. Use whiteboards to present answers.

  3. Perimeter x 2 Area x 4 Perimeter x 4 Area x 16

  4. Perimeter = 30 units Area = 36-4-3= 29 sq units P = 29 + 10 + 23.5 = 62.5 m

  5. P = 14 + 14 + 35 + 35 = 98 in

  6. C = 3.14 (10)= 31.4 in C=3.14(56)=175.84 ft.

  7. Finish the rest of the problems on the study guide for homework tonight. PROJECT-DID YOU BRING YOUR ROUGH DRAFT?
