Lesson Plan: Geometric Shapes (Circle, Square, Triangle)

Preschool Homework Lesson Plan on Geometric Shapes

This is the first part of a series of lesson plans involving math and shapes that can be done with preschoolers.

## Learning About Geometric Shapes such as Circles, Squares, and Triangles

Lesson Objectives:

• Learn to locate shapes within other objects/shapes.
• Cut a circle out of a square shape.
• Visualize space/use spatial logic.

Materials Needed for this Lesson:

• Scissors
• Sticks (Popsicle sticks work great)
• A bag
• Print-outs of the shape pictures (click the pictures to print them out at full-size)

### 1. Organizational Movement

What is the name of the pictured figure (it is a square?

Do these squares have the same number of sides (Yes, they are equal?

How can we compare the sides of each square (we can fold each one over from corner to corner so that the left, right, top, and bottom sides all are the same, plus if folded diagonally they are the same too? (1)

Picture 1. To print these pictures simply click on each desired picture and then print it once it loads at its full-size!

### 2. Creating a Square Out of Sticks

Make squares out of sticks. Discuss which is larger and smaller as well as where they are relative to each other.

### 3. Transforming a Square Into a Triangle

Cut an image of a square diagonally and observe what it looks like (it now is two triangles). Next, make a large triangle and a small triangle out of both squares via folding them. Observe how if the sticks have a diagonal one through them they too turn into triangles.

### 4. Creating Figures

Build a house out of multiple triangles recombined into squares and individual triangles. Then, stack the triangles on top of each other like a little Christmas tree (2).

Picture 2.

### 5. Transforming a Square into a Circle

Cut a circle out of square. Ask what shape it is (it is a circle). Now you try to cut a circle out of a square.

### 6. Draw the figure that is missing.

Look at the picture (3, The first and the second row show three figures (circle, triangle, square in different orders) There are only two shapes in the bottom row. Draw the figure that is missing.

Make your own activity out of the above images (4,5).

Pictures 3,4,5.

### 7. Take a Break

Do a physical activity for a break (jumping jacks, dancing, whatever you want!

### 8. Coloring the Figures

Color in this drawing so that there is a red triangle on top, a yellow circle underneath that triangle, and a blue circle at the bottom. Use visualization to accomplish this. (6)

Picture 6.

### 9. Arranging the Figures

Take three circles, triangles, and squares of different colors (red, yellow, and green). (4)

Arrange the figures an assortment of ways:

• Take a red circle. Place a yellow triangle to the left and a green triangle to the right.
• Take a red triangle, put a yellow triangle to the left of it.
• Take a green triangle, put a green circle underneath it and a yellow circle above it.

### 10. Touch the Shapes

Put different sizes and shapes of the geometric shapes pictured in a bag. (7)

Touch the shapes and identify what they are before pulling each one out of the bag.
