Mathepillar is an outrageously fun and very challenging game in which players have to order falling numbers on a number line by positioning their caterpillar in the correct place to catch the numbers. There are nine stages to the game, and each requires students to count by different numbers. For example, in the first stage, players simply have to order 1-10 on the caterpillar segments. In the next stage, it progresses to counting by two, then threes, fours, and so on. Each stage presents a new setting and new challenges.
