Now look back at your working. Can you find a quick way of doing these calculations in your head? Try this exercise again with different numbers.

## A Mathematics Lesson Starter Of The Day

• Transum,
•
• This is just the sort of quick activity we should squeeze into our lessons more often. It is a classic arithmetic task that leads to pupils thinking about place value and how it might help them with their mental calculating abilities. This activity won't take long and is ideal for taking advantage of the time just before the main part of the lesson starts. Did it work well for your class?
