Introduce your children to all sorts of ways to practise and apply their understanding of adding and subtracting tens with this Year 2 Add and Subtract 10s Modelling PowerPoint! After a quick warm-up of working out ten more and ten less of different numbers, the slideshow leads you and your class through several varied fluency, reasoning and problem-solving questions, all of which can be found in our corresponding worksheets for this lesson. It's a great place to start before moving your children on to that independent work.

Every question has its own answer slide, so you'll be able to immediately spot any misconceptions and give helpful feedback. The reasoning question has its answer revealed in two stages, so children get another chance to work out the reasoning once they know the correct answer. Super helpful!
