LESSON 11.2
Hands On • Combine Three-Dimensional Shapes
Teaching for DepthWe are familiar with different three-dimensional objects because we live in a three-dimensional world. Children are in frequent contact with common three-dimensional shapes, such as balls (spheres), cereal boxes (rectangular prisms), and toy blocks (cubes). While many children can identify the shapes of these real-world objects, they may find it difficult to combine and describe three-dimensional shapes. Work with children to first identify the two shapes they will be putting together. Then ask the following questions to help deepen understanding:
•How is your new shape like the shapes you used to build it? How is it different?
•Can you put together a sphere and another shape to make a new shape? Why or why not?

How can you combine three-dimensional shapes
to make new shapes?
with the Interactive Student Edition
Essential QuestionHow can you combine three-dimensional shapes to make new shapes?
Making ConnectionsInvite children to tell you what they know about combining three-dimensional shapes. Hold up models one at a time and ask children to name the shapes.
Could you stack this shape with another shape? Answers will vary.
In what ways other than stacking can you combine shapes? Possible answer: I can put them side by side.
Learning ActivityWhat is the problem the children are trying to solve? Connect the story to the problem.
• Are there different ways to stack two of the same shape? Answers will vary; for cylinders and cubes, no; for rectangular prisms, yes.
• Describe the shapes you can make by stacking two of the same shape. Answers will vary.
Literacy and MathematicsChoose one or both of the following activities.
• Have children find three-dimensional shapes around the classroom and see how they can combine them.
• Have children use blocks to build a structure and describe how they combined the blocks to make new shapes.

8 = 4 plus what? 4
11 = 9 plus what? 2

Read aloud the problem with children. Working in pairs or small groups, have children first model the problem with same-sized cylinders and cubes.
Mandy stacks one cylinder on top of another cylinder. Carl stacks one cube on top of another cube. What new shapes did Mandy and Carl make?
• Does it matter where on the cylinder you stack the other cylinder? Why? Possible answer: Yes. They have to be stacked on their flat surfaces or they will roll.
Have children trace the dashed lines on their pages to represent the new shapes.• When you stack two cylinders, what is the
new shape you get? How do you know? cylinder; Possible answer: It has flat surfaces and one curved surface.
• When you stack two cubes, what is the new shape you get? How do you know? a rectangular prism that is not a cube; Possible answer: It has 6 flat surfaces, 2 squares and 4 rectangles that are not squares.

ELL Strategy: Restate
Direct children’s attention to the models of three-dimensional shapes. Review the names and the attributes of each shape.• Can you put two shapes together to make a
new shape? Provide time for children to explore with the models.As they explore, talk about the new shapes and their attributes until children are confident in their ability to identify the shapes.

SMARTER
Exercise 11 assesses whether children can combine three-dimensional shapes to make new shapes. Children must look for one rectangular prism and one cone in each answer choice. The first two choices each contains only one of those shapes. If children only select the third or fourth choices, remind them that the problem may have more than one correct answer.
Essential QuestionReflect Using the Language Objective Have children compose a note to a child who is at home sick today, to answer the Essential Question.How can you combine three-dimensional shapes to make new shapes? Possible answer: I can match two flat surfaces to combine shapes.

What New Shapes Can You Make?Materials models of three-dimensional shapes
Investigate Have children work in small groups. Give each group the same three shapes. For example, you might give each group a cube, a cylinder, and a cone. Then have children combine the shapes to make a new shape. Once groups have made their new shapes, have them share their shapes with the class. Then repeat the activity with a different set of three shapes, such as a cube, a non-cube rectangular prism, and a cylinder.Math Talk Use the following questions to guide discussion about ways to make new shapes.
• How can you describe your new shape? Possible answer: It has a cube, a cylinder, and a cone; the cylinder is stacked on the cube; the cone is stacked on the cylinder.
• How else could you stack a cube, a cylinder, and a cone? Possible answer: You can stack a cube on a cylinder or a cylinder on a cube because they have flat surfaces on each end. You cannot stack a cube or a cylinder on a cone because the top of the cone is pointy.
Summarize Guide children to the conclusion that a shape’s attributes, such as flat and curved surfaces, affect how it can combine with other shapes.
