With differentiated questions, this Year 3 Add Two Numbers (Across a 100) Varied Fluency resource helps you to teach every child in your class how to add together numbers where the calculation crosses the hundred. To make things simpler for you, and to cut down the time you spend marking, we have included an answer page with this resource.

Use in class, as part of an intervention, or send out as homework; the choice is yours. Don't forget to check out our other resources for this lesson, too, which include a modelling PowerPoint, reasoning and problem-solving worksheets, and much more!
