About this worksheet

A number line turns adding into counting on: start at the first number and hop forward once for each number you add. On this grade 1 worksheet each line shows an addition sentence and a number line with the hops already drawn, and your child counts along the line to find where the hops land and writes the sum on the line.

The number at the landing spot is hidden, so your child has to count the hops, not read the answer. Support and standard sheets use a line to 10, and challenge sheets use a line to 20. Point at the start number and count each hop out loud together.
