Finding the difference using a number line

Good idea, very well presented. I think that step 5 should read 'Add up your jumps'. Some students will interpret 'Count up your jumps' literally to give, in the first example, the answer 3. With this edit, I would recommend this resource with a 5 rating, without, I probably wouldn't use it.

Wow, this is fab. I have an interview with this exact lesson so this has given me some great ideas. Thank you!
