Give children the opportunity to apply their addition and subtraction skills with this Year 3 3-Digit Numbers and Tens Reasoning and Problem Solving resource. We've given you both choice and challenge in this resource, as it has been differentiated three ways. Each worksheet includes two different reasoning style questions, and finished off with a problem-solving style question. We've included two of each question type of question to ensure children are confident at the skills needed to answer each style.

Use this as an independent task, after a number of varied fluency questions, as a way to incorporate mathematical discussion into your class or as a small group activity too. The handy answer sheet will have you whizzing through your marking too!
