I recently taught my class Year 2 two- digit subtraction, which began with a lesson where the children used manipulatives such as Base Ten sticks, ten strips and counters, Slavonic abacuses etc in pairs to subtract one two-digit number from another.
The next lesson was an individual task, which is where my worksheets came in. They are differentiated 4 ways and I put a fair bit of effort into making them, so I thought I’d share them (download link is at bottom of post).
The questions are different on each sheet, so once a child completes one level they are free to ‘move up’ and try something a bit more challenging. Before moving up, a child could either come to the teacher or a TA for a quick check, or you could have the pupils self-check their answers (though this does take some coaching to discourage copying! I mean, my pupils are only 6/7!)
The progression on the sheets is:
1. Base ten already drawn of the larger number, for child to subtract by crossing out. There is no bridging here (just questions like 54-21).
2. They have to draw the numbers from scratch as base ten, but there is still no bridging.
3. They are not yet bridging across a ten but they are answering the questions using just a written/mental method. There is a final challenge question which has a modelled version of bridging.
4. Children are bridging through a ten to find the answer. (eg 53-28). There is a final mastery question about subtraction.
NOTE: The sheets are labelled with the differentiation terminology used at my school: Base Camp, Hill Climber, Mountaineer and Everest.
NOTE: I’ve included an answer sheet for the worksheets to save you time!
LEARNING TO DO BEFORE YOU APPROACH THIS: Subtracting a single-digit number from a two-digit number (eg 25 – 4) and in particular examples of this where children have to bridge through ten (eg 36-8).

I have a wide range of maths abilities in my class and these are beautifully differentiated. Thank you!
