Objective: Students will learn to identify a square, triangle, rhombus, trapezoid, and hexagon.
Manipulative Activity: Distribute squares to all the children in the class. Hold up the square and ask the children to describe the shape. Write the students' responses on the board. Say the name of each shape and have the students repeat it, following the same procedure for each one: square, triangle, rhombus, trapezoid, and hexagon.
Technology Activity: Students will use a pattern block applet written by Jacobo Bulaevsky to reinforce the identification and naming of each geometric shape. Depending on the availability of computers for your students, this activity could be done individually, with partners, in groups, or as a class.
Have students go to Describe the Shape.
Paper/Pencil Activity: Depending on the level of your students, you can have them complete this activity individually or with assistance. Here are some possible activities:
 Print this triangle grid paper to use to make a pattern block design.
 Students color and list the shapes used.
 Students draw their own design using pattern block shapes and write a story about it.
