You've never seen flash cards as good as Baby Einstein's before! and with these cards you can introduce your child to numbers and shapes in a baby- / toddler-friendly way. You may not realise it, but babies already have a firm grasp on simple mathematical principles (they know when their plate is full and when it is empty and they certainly know when a play-mate has more toys then they do!). Babies also have a developing appreciation of shapes and patterns. 'Numbers and Shapes' flash cards were created with these two things in mind and will support your child's ability to develop the building blocks of maths and geometry.
