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.

Build a New Shape | Build a New Shape is a lesson for building composite shapes from triangle(s), square(s) and trapezoid(s). This lesson uses a story and certain pattern block manipulative to help students to gain this skill. |
Puzzled by Pattern Blocks! | In this lesson, the students will use two-dimensional pattern blocks to compose new shapes and fill in composite outlines of shapes. |
Life Jackets | In this MEA the students are to decide what criteria is the most important for a company to consider when choosing life jackets. Students will use data tables of qualitative information to solve the problem. Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom. |
Fun with Shapes | In this lesson students explore the composing of new shapes from other two-dimensional shapes. The students will utilize math benchmarks as they analyze math solutions and explain their solutions. Since the lesson uses composing, it is also a good lesson to use to show decomposing (taking a shape apart). |
Quilt Squares | Students will use pattern blocks to create a quilt square for the Quick Quilters Society. They will have to consider information on a data chart to help them create their squares. They will have to add up the cost to make their square, too. Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations.

Composite Creature | The students will use pattern blocks to build and draw new composite geometric shapes, ultimately using composite shapes to form a creature. |
Shape Detectives | In this hands-on lesson, students will become Shape Detectives as they identify the two-dimensional shapes, such as triangles, squares and rectangles, needed to build three-dimensional figures including rectangular prisms, square pyramids and cubes. The students will gain an understanding of how two-dimensional shapes are joined together to form three-dimensional figures as well as creating an edible example! |

Shape Tool | This virtual manipulative allows you to create, color, enlarge, shrink, rotate, reflect, slice, and glue geometric shapes, such as: squares, triangles, rhombi, trapezoids and hexagons. |
Shape Cutter | This virtual manipulative allows students to draw geometric shapes and then decompose and recompose them into other shapes, using slides, turns, and flips to cut and move pieces around. |
