Solid Shapes: Identifying 3-D Shapes
Students will be able to identify geometric shapes in objects they use in their daily lives.
Introduction (10 minutes)
- Tell students that today they are going to learn about 3-D geometric shapes.
- Show them examples of 2-D and 3-D shapes, such as a circle and a sphere.
- List all of the names of the shapes that your students will be working on.
- Ask them to name some shapes they see around them.
- Read the book Shapes in Our World by Moira Anderson.
Explicit Instruction/Teacher Modeling (10 minutes)
- Make 3-D shapes by folding paper.
- Show the folded shapes to your students, and name each shape clearly.
- Display the written name of the shape next to the corresponding shape.
- Show them some everyday objects that correspond to these shapes.
Guided Practice/Interactive Modeling (10 minutes)
- Have your students explore the premade folded shapes, everyday objects, and names of the shapes.
- Encourage them to count the number of sides of a 2-D shape and compare with its 3-D shape.
- Ask them to look at the names of the shapes and say the names.
- Give each student a copy of the Sort 3-D Shapes worksheet, and go over the worksheet with them.
Independent Working Time (15 minutes)
- Instruct your students to complete the worksheet.
- Enrichment: Have your students write the names of the shapes without referring to the name tags. Give them directions to make the folded shapes.
- Support: Help your students by writing the name of the shape with a highlighter, and have them draw 2-D shapes on paper.
Assessment (5 minutes)
- Ask questions about the shapes, their names, and commonly seen objects in the environment.
Review and Closing (10 minutes)
- Go over all of the shapes and their names.
- Give each student a turn to match the shape to its name.
- Ask your students to name common objects in a shape that you call out.
