Whether called regrouping, exchanging, decomposition or any term, these examples demonstrate the key is for children to have the opportunity to be playful and flexible with numbers to be able to apply their understanding to increasingly varied and complex contexts.

Buckle up and get ready for a smoother journey to multiplication success! Rachael Brown examines…. What happened to partitioning and exchanging? Why is being able to regroup so crucial? Regrouping for addition within 20 To be able to regroup increasingly more complex whole numbers, fractions and decimals, children need to experience and understand all numbers can be regrouped flexibly to help support calculations.

Regrouping to support subtraction A key feature of our ESSENTIALmaths plans is that we provide opportunities for children to experiment with, compare and evaluate different strategies, through discussion with others. Explain how regrouping can be used to solve this problem.
