1. Print and cut out the strips of varying lengths on BLM: Similarity Challenge Strips. Cut only on the solid lines; do not cut on the dotted lines.
2. Place the strips in a paper bag. Without looking at the contents of the bag, the dealer hands out eight strips to each player.
3. Each player constructs two similar figures using a scale factor other than 1. The similar figures may be triangles, quadrilaterals, or any other polygons.
4. If neither player can construct similar figures with the strips dealt, the dealer hands out two more strips to each player. Dealing continues until a player can construct similar figures. The successful player’s score is equal to 2n, where n equals the number of sides on each figure.
5. Return all strips to the bag and rotate play to a new dealer.
6. Play continues for at least two complete rounds of play. The winner is the player with the highest score.
