KG Math HD has 30 different math games designed for early school aged children (grades K – 2). It sells for $1.99 but I downloaded on a FREE day. It is cute, colorful, and easy to use. Concepts taught include counting, adding, subtracting, time, simple fractions, weight, colors, seasons, symmetry, etc. Many of the games seem overly simple for the intended age group – such as top/bottom, in/out, same, different, drag the shape to its shadow. Others games could be better with simple modifications – the time game has no numbers on the clock, the colors games and the shapes game show the word but do not pronounce it. In general I feel that this app is more appropriate for preschoolers than early school age kids. Check it out for yourself on a FREE day.
