Let's practice number bonds! A number bond is like a number puzzle. You can split a big number into two smaller numbers or combine two smaller numbers to make a big number. This workbook will show you how to do it. Follow along and finish all the activities!

First graders should learn that number bonds are a way of understanding and visualizing how numbers can be split into smaller parts. They should know how to apply number bonds to simple addition and subtraction problems by breaking down numbers into their component parts, such as recognizing that 5 is made up of 2 and 3 or 4 and 1.
