About this worksheet

A number pattern follows a rule: it goes up or down by the same amount each time. Spotting the rule is an early step toward algebra, and it makes skip counting and addition strategies much easier. On this grade 1 worksheet each line shows five numbers in a pattern with one missing, and your child works out how much the numbers change by and writes the missing one on the line.

Every pattern goes up by 1, 2, 5 or 10 from a friendly starting number such as 5, 10, 20 or 35. Support sheets use steps of 2, 5 and 10, standard sheets add steps of 1, and challenge sheets also count down. Ask your child to say how much the numbers change by from one to the next before filling in the gap.

Worked example

The pattern is 20, 25, ____, 35, 40. The numbers go up by 5 each time, so the missing number is 30.

Common mistake

Adding 1 to the last number instead of finding how much the pattern really changes by.

Helpful hint

Look at the first two numbers. How much did it change by? Use that for the gap.
