Grades K-2 Objective Students will be able to join pattern block pieces together to cover a region and to identify and describe numerical relationships found among pattern block shapes. Overview of the Lesson Using square tiles students begin the lesson by finding all of the different rectangles that could be made from 12 squares. Students experiment with pattern blocks to find ways to use smaller pattern blocks to cover larger ones. Using shapes from the previous lesson, students decorate colorful paper bag vests with shapes and patterns. Activity Sheets are located at the bottom of the .pdf Lesson Plan.
Procedure Begin the lesson with a warm-up activity.
Distribute a set of square tiles to each student. Ask the students to describe different ways that a rectangle could be made using 12 squares. As students use the square tiles and respond, draw a picture on the board to illustrate each rectangle. Circulate through the classroom and give each student a square, rhombus, trapezoid, or hexagon. Note the cut-outs pieces are the same size as the pattern blocks.
