Subtraction with Regrouping Check In
A formative assessment tool to assess where students are when working on the vertical written subtraction strategy involving regrouping. The assessment asks students to complete a series of problems involving basic subtraction, subtraction with regrouping, multiple regrouping, and regrouping when numbers contain zeros. This resource is part of a larger unit of work on Subtraction with Regrouping- Year 3.
Learning goals
- We are learning to use a range of mental and written strategies to solve simple addition and subtraction problems.
- We are learning to solve problems by using number sentences for addition or subtraction.
- We are learning to partition, rearrange and regroup numbers to 10 000 using place value groupings.
- We are learning to use number sentences and partitioning to demonstrate the connection between addition and subtraction.
- We are learning to add and subtract one- and two-digit numbers, using a variety of strategies, e.g. partitioning, doubles, near doubles, bridging to 10 and rearranging and regrouping of numbers.
- We are learning to add and subtract two-and three-digit numbers using place value groupings.
