Missing addend worksheets for 1st grade
A missing addend problem like 8 + _ = 15 asks a child to think about addition and subtraction at the same time. It is a key 1st grade step because it shows the two operations are connected.
Our Addition & Subtraction Within 20 pack has 20 printable pages in order: addition, subtraction, mixed practice, then missing-number problems. Working through it in that order means children have the facts before they meet the missing numbers. Every page has room for a name, date and score, and the full answer key repeats each page with the answers filled in.
It is a PDF on US Letter paper and one of five packs in the 1st and 2nd Grade Math Worksheet Bundle.
