Is the number line still the main thing standing between your class and confident negative-number calculations? This substantial 36-slide interactive lesson gives pupils extensive, self-marking practice adding and subtracting negative numbers, with nothing to prepare beforehand.
Pupils work through adding and subtracting negative numbers step by step, building the fluency within the Year 6 National Curriculum area of number and place value. The substantial slide count means pupils get repeated exposure to different calculation types — not just one worked method repeated — before moving on to more complex problems.
A strong addition to any Year 6 number topic, whether used as the main teaching input or as a longer independent practice session. The generous slide count also makes it a natural resource to return to for revision closer to any end-of-topic assessment.
