MATHEMATICAL PRACTICES (See Mathematical Practices in GO Math! in the Planning Guide for full text.) MP1 Make sense of problems and persevere in solving them. Materials MathBoard, Two-Dimensional Shapes (to combine) (See eTeacher Resources ), tape FCR Focus: Common Core State Standards 1.G.A.2 Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. Language Objective Partners explain to the class and demonstrate how acting it out can help them make new shapes from combined shapes. Make New Two-Dimensional Shapes LESSON 12.5 Learning Objective Make new shapes from composite two-dimensional shapes using the strategy act it out.Children can also look for composite shapes in cars, toys, packages, and clothes. Ask children to look at houses and other structures between home and school to find where shapes may have been put together to form a design. Understanding of shapes is needed to plan structures so people can work and drive safely.

Explain that if architects did not know how to put shapes together and take them apart, they could not make plans for buildings or bridges. Using an understanding of how shapes may be composed or decomposed is an important skill in life and in many careers. Tell children that real-life problems are solved with all kinds of mathematics.
