Find the Missing Numbers Worksheet
The Find the Missing Numbers worksheet gives first graders short counting sequences and number sentences with one or two blanks. Children practice counting forward, spotting missing numbers, and using simple addition and subtraction facts within 20.
Six-year-olds often know the counting chant, but kids can stall when a blank sits in the middle of a row. Number sense grows when children see that 16, 17, 18, 19, 20 follows a steady pattern, and that 13 take away 10 leaves 3.
Sit beside your child with a pencil and start with one row, such as 16, blank, 18, blank, 20. Ask your child to whisper-count from the first number, write the missing number, then check the matching addition or subtraction sentence out loud.
The page mixes four short sequences with four small equations, so practice feels varied without becoming a pile of problems. The missing spaces are placed in different spots, which helps children look at the whole pattern instead of guessing the next number every time.
