This activity comes with 16 cards that have three consecutive numbers from 1-6 on them placed on the edges of the cards. It was created to help children learn how to read and count numbers and to understand number order. The rule is to try to create as long of a chain of cards as possible by making sure the numbers are one larger or one smaller on the next card. Children match sides of them to each other so that each card is one larger or smaller than the one before it. This helps them to recognize consecutive numbers. It also helps to read and recognize numbers. The goal is to use as many sides of each card as possible. The challenge exists in the fact that the numbers are not all the same on each side. Rather than counting “1, 2, 3, 4, 5...” in a linear manner as is typical, the inconsistency in numbers helps to get children to recognize patterns within counting. For example, two edges of two cards next to each other might read from left to right “1, 2, 3… 2, 3, 4…” then, “4, 5, 6… 3, 4, 5…”, and so on.
