This Year 3 Add and Subtract Mass Reasoning and Problem Solving resource is differentiated into three levels to target a range of learning needs. Each worksheet includes six questions with a variety of representations, including part-whole and bar models. Pupils will be able to apply their skills on questions that are appropriately pitched with progression ranging from multiples of 100 to some measures being represented as fractions.

This resource could be used independently or in small groups. We've also provided an answer sheet for ease of marking and to save time.
