This unit is the second of two books of games for the early years. The first book consisted of approximately 20 games focused primarily on early number sense, addition, and subtraction. This collection expands on that work by providing more games on number and operation, but it also includes games for early geometry, time, and early algebra. The two books of games were designed primarily for K-1 because in the early years math workshop often consists of a mixture of investigations and games. But the books can also be used as yearlong resources for small group work, differentiation, and intervention. Each book includes approximately 20 games that you can choose from as you consider the needs of your students. The two books of games can also be used in Grade 1.
