Lesson details
Key learning points
- Compensation can be used to solve subtraction calculations.
- Equivalence can be used to solve subtraction calculations.
- Look at the numbers and decide on the most efficient strategy to use.
Keywords
Difference - The difference is the result after subtracting one number from another.
Adjust - When you adjust you make a change to a number. This is done to make a calculation easier to solve mentally.
Common misconception
Lots of children have an understanding of goal difference from experiences outside the classroom but this might be the first time some children have encountered it and it may cause confusion.
Consider pre-teaching if that is a possibility or introduce it in a PE context to begin with. You could even keep score of any playtime games for the days leading up to the lesson to give some real life context.
