Number bonds, skip counting and the math facts kids learn from kindergarten to third grade.
In the Common Core State Standards, kindergartners learn to find the number that makes 10 with any number from 1 to 9, and second graders are expected to know all sums of two one-digit numbers from memory. Number Bonds explains what a number bond is, how the part-part-whole picture works and how to practice the bonds to 10 and 20 with everyday objects.
Kindergartners count to 100 by ones and tens, second graders skip-count by 5s, 10s and 100s, and third graders are expected to know every product of two one-digit numbers from memory. Skip Counting has the skip counting charts for 2s through 10s, the patterns that make each one easier and the games that turn it into practice for times tables.
