Shape Identification: Bake 'N Buy
Students will be able to identify, name, and recreate one dimensional shapes.
Introduction (5 minutes)
- Begin the lesson by playing the Preschool Shapes Song for your students. Practice integrating movement into the song by having students draw out the shapes with their fingers or forming the shapes with their arms.
Explicit Instruction/Teacher Modeling (10 minutes)
- Write "Shapes can have sides and vertices. Circles don’t have sides or vertices." on the board.
- Underline the words “sides” and “vertices” and ask students to turn to their nearest partner and think of a definition for each of these two words.
- Explain to students that most shapes have sides, or lines, that create the figure.
- Write the word rectangle and draw an example of it on the board. Point out that rectangles are shapes that have two long sides and two short sides.
- Continue on to define the word vertices by drawing 4 circles around the angular points of the rectangle. Tell students that every time two lines join they create a vertex and that when you have multiple of these joined lines you call these vertices.
- Draw a circle and ask your students if the circle has sides or vertices. Continue to draw and classify the number of sides and vertices of squares, triangles, and hexagons.
Guided Practice/Interactive Modeling (10 minutes)
- Allow students to practice identifying and labeling shapes by asking them to look around the classroom for different shapes.
- When they have finished locating shapes, allow the students to come up to the board to draw and describe how many vertices and sides each of those shapes has.
Independent Working Time (30 minutes)
- Combine students into working pairs and have them play Bake ‘N Buy by distributing a sheet of wax paper, a ball of clay, and toothpick to one partner and a Fun With Shapes worksheet to the other.
- Tell your students with the clay that their job will be to "bake" the five shapes they just learned by making them out of clay and writing the name above each shape with a toothpick.
- Let the other half of the pair know that they can use the paper shapes as money to “buy” the baked shapes but only if they are able to match it with its shadow and describe how many sides and vertices it has to the baker.
- Have the partners take turns baking or creating the paper shapes.
- Enrichment: Challenge advanced students by having them create patterns with shapes based on their attributes, such as color, number of sides, or number of vertices.
- Support: Help below level students by providing them with cookie cutters that can create a more defined shape that they can then replicate and label with more ease.
Assessment (10 minutes)
- Issue a copy of the Shapes Quiz worksheet after your students have completed their independent activity. Read the instructions and the names of the shapes aloud as they draw the corresponding figures.
Review and Closing (5 minutes)
- End the lesson by asking students to create shapes with their hands, their partners, or with their crayons as you call out each shape’s name.
