I can understand perimeter as the boundary of a shape. Lesson 10 Learning Goal I can understand perimeter as the boundary of a shape.

Say the multiplication sentence Lesson 10 I can understand perimeter as the boundary of a shape. Count by twos to 20. 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 1 two 2 twos 3 twos 4 twos 5 twos 6 twos 7 twos 8 twos 9 twos 10 twos Say the multiplication sentence Equivalent Counting with Units of Two

Lesson 10 I can understand perimeter as the boundary of a shape. Trista uses all seven of her tangram pieces to make a square as shown. One side of her square is 4 inches long. What is the total area of the two large triangles? Explain your answer. 4 inches Application Problem

Lesson 10 I can understand perimeter as the boundary of a shape. Trista uses all seven of her tangram pieces to make a square as shown. One side of her square is 4 inches long. What is the total area of the two large triangles? Explain your answer. 4 inches 4 x 4 = area of square 4 x 4 = 16 sq. inches 16 ÷ 2 = area of large triangles 16 ÷ 2 = 8 sq. inches The area of the two large triangles is half of the area of the square. The area of the two large triangles is 8 square inches. 4 inches Application Problem

Lesson 10 Use suggested materials and Problem Set I can understand perimeter as the boundary of a shape. Use suggested materials and Problem Set for Concept Development. Concept Development
