Some good games for kindergarten students are identifying 2-D and 3-D shapes, coin recognition, identifying patterns, counting games and sorting items by color and then finding the number of items in each color group formed. Another game can be to identify simple geometric shapes like a square, circle and triangle.
Some websites that provide some of these games for kindergarten children are PBS Kids, Education and Learning Games for Kids. PBS Kids has a math game where children can differentiate between two snowflake shapes. The Education website has a very extensive selection of games that kindergarten kids can play, which are all math related. Some of these games include sorting items, finding measurements, comparing 2-D and 3-D shapes and other math topics like adding and subtracting. The Learning Games for Kids site also provides many math games for kindergarten students, such as word search puzzles of geometry shapes.
