Early MathDrawing hops on a number line to 100
Draw the hops on each line, then write the answer.
A number line stops being a picture the day a child draws on it themselves. These free printable worksheets give a sum and a bare 0-to-100 line, and ask for the hop that shows it.
If they get stuck

The answer key prints on a separate page.
Each question prints an addition or a subtraction and leaves the line empty. The child marks where to start, draws the hop, and writes where it ends — which is what representing a sum on a number line actually means, as opposed to reading somebody else's.
The line is ticked every five and numbered every twenty, and every hop lands on a tick. A hop that ended between two marks would ask a child to guess, so the questions are built from the same ruling the line is drawn with.
