Lesson Details

Key learning points

By looking carefully at the numbers involved, you can choose the most efficient strategy.
When numbers are close together, finding the difference is the most efficient strategy.
Sometimes, we can use known addition facts to make finding the difference even more efficient.

Common misconception

Children can often be overwhelmed by the amount of visual data they are presented with.

Expose children to graphical data as much as possible outside of maths lessons. Encourage children to make simple bar charts with cubes so they understand their formation and liken the searching for specific values to search and find books.
