What are number line jumps?

Each problem, like 7 + 4, comes with a number line. Children start at the green dot, draw one jump for each one they add or take away, and write where they land.

Which ranges are there?

0 to 10, up to 20, and tens up to 100.

Are answer keys included?

Yes. The key draws the jumps and the answer.

Seeing addition and subtraction

A number line shows adding as moving forward and taking away as moving back. It is the bridge from counting objects to mental maths.

NCF and NCERT links

Class 1The NCF-FS (C-8.3) has children counting forwards and backwards from any number between 0 and 99.
Class 2Children skip count on a marked number line, and add and subtract up to 99 by breaking numbers apart and joining them again (C-8.6).

The NCF-FS asks for concrete work before pen and paper. Draw a number line on the floor or verandah with chalk and let children jump the problem before they draw the jumps on the sheet.

The tens line to 100 is a good bridge to Class 2 sums like 47 + 30: three jumps of ten instead of thirty jumps of one. Ask children to say where they will land before they jump, then check, so the line becomes a tool for estimating as well as counting.
