Help your children to answer questions involving adding and subtracting single-digit numbers to and from 3-digit numbers with this Year 3 3-Digit Numbers and Ones Modelling PowerPoint! The slideshow introduces your class to an assortment of varied fluency, reasoning and problem-solving questions, all designed to help your kids to understand addition better and apply that knowledge. Helpfully, the questions all correspond to those included on our worksheets for this lesson, so this is a great place to start before moving your class on to that work.

Answer slides follow every question, so spotting misconceptions and giving feedback is a doddle. The answer to the reasoning question is revealed across two slides, to give children a further chance to work out the reasoning once they have seen the correct answer.
