Objective: Students will learn to create patterns using squares and triangles.
Manipulative Activity: Draw a pattern on the chalkboard and ask the children to describe the pattern using the names of the shapes. Repeat with another pattern. Distribute the triangle and square blocks. Have the students create a pattern using the triangles and squares, and draw and color their patterns on paper. Repeat the activity using different shapes.
Technology Activity: Students will use a pattern block applet written by Jacobo Bulaevsky to build patterns using the different polygons.
Have students go to Making Patterns.
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 can make their own patterns using pasted shape cutouts or stickers on paper.
 Students can make a number pattern and have a partner guess what the pattern is.
 Students can write about a pattern that they use every day.
