This worksheet is designed to help students practice number bonds to 20. Number bonds are pairs of numbers that add up to a certain sum, in this case, 20. The worksheet provides part-part-whole models, where students have to fill in the missing numbers to complete the bond. For example, if 8 is given as one part, the student would need to write 12 as the other part to complete the bond to 20. The purpose of this worksheet is to reinforce students’ understanding of number relationships and improve their addition skills within the number range of 20.
