Grade 1 Math: Number unit
Students count, read and build numbers to 50 with ten frames and base ten blocks, compare and order them, guess and check, and skip count by 2s, 5s and 10s. They share fairly, make equal groups, and add and take away to 20. They finish by making a number poster that shows one number in many ways.
