Subtraction Pirate

This visually appealing and vibrant game has been designed to provide students with an engaging way to practice two digit subtraction with regrouping. This resource includes a reproducible recording sheet, which makes it a great formative assessment tool. It could be used as an extension activity or during mathematics rotations.

Learning goals

  • We are learning to solve problems involving modelling addition, subtraction, equal sharing and grouping, using different strategies.
  • We are learning to recall addition facts to 20 and apply to related subtraction facts using a range of strategies.
  • We are learning to use a range of mental and written strategies to solve simple addition and subtraction problems.
  • We are learning to add and subtract two-and three-digit numbers using place value groupings.
  • We are learning to partition, rearrange and regroup numbers to 10 000 using place value groupings.
  • We are learning to recognise and explain multiplying and dividing by 10 using place value charts, numeral expanders or sliders and to use a calculator to understand the relationship between the place value of digits when multiplying and dividing by 10.
  • We are learning to partition, rearrange and regroup numbers to at least tens of thousands using place value groupings.
