Get your class prepared for adding tens to a 3-digit number by using our Year 3 Add 10s Across a 100 Prior Learning worksheet. This resource includes a variety of questions that cover adding 2-digit numbers and ones crossing ten, which is an objective covered in year 2 and can be used as a stepping stone for the new learning in this lesson. We've included varied fluency, reasoning and problem-solving questions to test your children's skills.

Use at the start of the lesson to gain a better understanding of where your class are at and where they might need additional support. Alternatively, this can be used as a morning activity, or in a small group to help children feel more confident in this skill. A handy answer sheet is provided to aid marking too.
