Find the Missing Numbers Worksheet

Find the Missing Numbers Worksheet gives first graders a focused way to practice counting forward and number sense. The page asks children to fill blanks in short number sequences, including 1 to 5, 3 to 7, 13 to 17, and 6 to 10, then complete simple addition and subtraction facts with missing parts.

At age six, many children can chant numbers out loud but slow down when two spaces disappear from a row. Missing-number work helps children notice the number before and the number after, which supports early addition, subtraction, and mental math.

Sit beside your child and start with one row at a time. Ask your child to point to each number, whisper-count through the row, write the missing numbers, and then read the matching addition or subtraction fact out loud before filling the blank.

The worksheet keeps the work small and clear, with four short sequences and four simple equations on one page. The mix helps a parent or teacher see whether a child needs help with counting order, operation words, or reading a number sentence.
