A number line turns adding into moving: the child puts a finger on the first number, hops forward one step at a time as many times as the second number says, and the number they land on is the answer. Every row on this sheet has its own number line with a dot on the first number and the sum written next to it, like 3 + 2. The first row shows the hops drawn in as an example, so the child sees what to do before starting.

Set Sums to Sums to 10 for a line from 0 to 10, or to Sums to 20 for a longer line with answers from 11 to 20. Choose four, five or six rows on a page. Every sum on a page is different, and the hops are always small enough to count.

Press New sheet for new sums. The answer key prints on a second page only when you ask for it. Every sheet prints in color or black and white, on US Letter or A4. Nothing to sign up for.
