Counting in 2s is the earliest multiplication skill taught which also helps children when dividing. It is usually practiced regularly, in order for the skill to be fluent, and children are also taught to recognize that multiples of two are even. Once the 2 times table is familiar, children will learn how to use the multiplication facts to solve division questions. For example, if they know that 2 x 6 = 12, then they may also recognize that 12 ÷ 6 = 2 or 12 ÷ 2 = 6
Use this quiz to practice multiplying and dividing by 2.
