We are a huge fan of learning through play. The 123 flashcards by Wildebras introduce your child to learn about numbers and number sequences in a playful way. The cards are also a handy tool for you as a parent to do math games. Addition and subtraction, for example, but it is also nice to have your child search for items in the house: can they find something of which there are three? Or have your child copy the numbers – on paper or in a container of kinetic sand, for example.
