Provide students with a set of 5" x 8" index cards (approximately 10 cards each). Give each student a set of pictures. Ask students to glue one picture to the front of each card using a Crayola® Glue Stick. On the opposite side of the card, instruct students to write the digit that represents the number of animals in the picture on the front of the card. Students can use Crayola® Crayons to write the digits.
