Challenge your child’s number sense by embarking on a number safari! Call out a number and ask your child to find an object or set of objects that represent that number. For example, the number four might be the kitchen table with four legs. The number two might be a set of salt and pepper shakers. Extend the safari throughout the house and have him find an example of three in each room. The more he plays the game, the stronger his math skills become as he associates abstract numbers with concrete objects.
