Play is a great way to introduce your child to a wide variety of mathematical concepts. For example, engaging in pretend play helps children practice many important pre-math skills such as symbolic thinking and problem solving. Playing with blocks is another fun way to teach your child about basic math concepts such as size and shape. Encourage her to sort the blocks using different attributes (shape, color, size), or let her create fun patterns. Letting your daughter explore the different shapes and helping her create different animals or objects out of the blocks also helps teach her geometry. You can also make everyday routines playful by counting objects, or pointing out different shapes and patterns in her surroundings.
