IIM 2016 Lesson Plan / Allison Cyr
Creating Composite 3-D Shapes Grade Level First Duration 45-60 minute lesson Overview In this lesson, the class will review characteristics of 3-D shapes using a 3-D shapes poem/song. The teacher will then introduce combining these 3-D shapes to make a new, composite structure using the design website Tinkercad. After watching a video of Peg and Cat, students will have the chance to create their own structures using 3-D objects from around the classroom. Subject Matter Math Lesson: Geometry – 3-D Shapes Learning Objectives • •
I can identify 3-D shapes. I can use 3-D shapes I know to make new shapes.
Standards CCSS 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.
Technology Components •
Tinkercad: Teacher and students will use Tinkercad on the interactive whiteboard to combine 3-D shapes to make new shapes: https://www.tinkercad.com/
•
PBS Kids & PBS Learning Media video: Students will watch the short video about using 3-D shapes around you to create new structures: Math in the Bath: Building a Rocket with Shapes | Peg + Cat *

Materials •
Computer, projector, interactive whiteboard, 3-D objects in the room students can use to build composite shapes (kickballs, boxes, cans, etc).

Prep for Teachers •
• • •
Download 3-D shapes poem/song Create a Tinkercad account and learn the basics to use with students. Have Peg and Cat video clip ready for viewing. Gather (or think of) some objects around the room students could use when creating their 3-D shape creations.
Introductory Activity Ask students: Have you ever been to a 3-D movie? How is it different than any other movie you’d see? Students should say something about things “popping out” of the screen instead of it just being flat on the screen. Explain: This is exactly like the two types of shapes we’ve been learning about. 2-dimensional shapes are flat on our papers, like triangles and squares. 3-dimensional, or 3-D shapes are solid figures that seem to “pop out” at us. Both types of shapes are all around us. Today we are going to learn more about 3-D shapes and use them to do some building.
Cross-Curricular Integration Activity Project or display the 3-D shapes poem and recite it once for the students. Repeat the poem, having the students join you. Optional: create actions for each object in the poem. Have students brainstorm some familiar objects that look like these shapes. Learning Activity Tell students that today you are going to be doing the work of two very important careers in our community: architects and builders. Architects design homes and other buildings by drawing or using a computer. Builders like engineers and construction workers bring the architect’s sketch to life. First, we are going to use a program called Tinkercad to design with some of the different 3-D shapes we just learned about in our poem. • • •

Review the names of the 3-D shapes (and teach any that weren’t in the poem) within the Tinkercad program. Using your interactive pen, drag and drop some 3-D shapes onto the work surface Explain to students that we can use these basic shapes and combine them to make new shapes. These are called composite shapes. Composite shapes are shapes that are made from two or more basic shapes. Putting the shapes together helps us make new structures. For example, if we combine a cone and a sphere, it now looks like an ice cream cone. Have students take turns coming up to the board and creating composite shapes. Ask them to identify the shapes they used and what they built. Do this until everyone has had a chance to use Tinkercad.
Culminating Activity Now that we’ve been architects using Tinkercad to design some composite shape creations, it is time to be the builders. Show students the Peg and Cat video. Discuss: What 3-D shapes did Peg and Cat use? What did they make with their shapes? Split students into groups of 3 or 4. Tell them that their group will have 10 minutes to gather 3-D shapes from around the room and use them to create a composite structure of their own. It can be one we deigned in Tinkercad or something new. After student groups’ creations are complete, have each group briefly share what they built and the shapes they used to create it. Students may want a notebook and pencil to sketch out their structures or to list the different 3-D shapes they use. If your students keep poetry books, give them a copy of the 3-D shapes poem to put in their books for future review and reading.
3D Shapes 3D shapes are fat not flat,
A cone is like a party hat!
A sphere is like a bouncy ball,
A prism is a building tall!
A cylinder is a can of pop,
A cube is like the dice you drop.
3D shapes are here and there! 3D shapes are everywhere!
