3-D Shapes...Create!

Explicit Instruction/Teacher modeling

• Ask, "Which one of these shapes is a 3-D shape?" Explain that 3-D shapes you can hold, while 2-D shapes are flat.
• Tell student that they are going to use clay to create 3-D shapes. Show students the Match 3D and 2D worksheet and review the 3-D shapes on the left side.
• Make a rectangular prism out of clay. As you form it, talk about how you are creating each attribute of the shape.
• When you are done, write "rectangular prism" on an index card. Tell students that they are going to label each shape they create to make a shape gallery.

Guided Practice

• Have students turn and talk about which 3-D shape they think would be the easiest to create and which would be the most difficult.
• Have students share their answers with the class, explaining why they picked the shape they did.

Independent working time

• Hand out clay, index cards, and the Match 3D and 2D worksheets to each student.
• Ask students to make a 3-D shape gallery and write the names of the shapes they create on index cards.
• As students work, circulate around the room and ask them to describe the shapes they made.
• Have students complete the Match 3D and 2D worksheets if they finish early.
