Kindergarteners build upon their number skills in this guided lesson which focuses on the numbers 11 to 20. Not only will kids learn to identify numbers, but also begin to associate them with certain values. It's an important concept for young mathematicians that requires lots of practice. You can give kids even more chances to extend learning with the accompanying numbers printables.

Multiplication is essentially repeated addition, or growing numbers by doubling, tripling, quadrupling, and so on. This unit presents mental models and strategies that help students learn and review the concept of multiplication. Students explore multiplication using arrays, partial products, doubling methods and the standard algorithm to solve numerical and word problems. Students will multiply whole numbers and simple decimals by base ten exponents (i.e. .3 x 103).
