The multicultural number cards teach young children the numbers 1 to 20. At the same time, each card includes a word and an "Urban Kidz" character from the All 4 Kidz Enterprises books. This means that children can practice learning language arts and review the life lessons taught by the All 4 Kidz Enterprises "Urban Kidz" characters. Each character is from a different background, so these cards are perfect for teaching acceptance and diversity as well as math.
