Lesson details

Key learning points

  1. We can use double facts to solve near-double calculations.
  2. We can double the smaller addend and add 1 If 4 + 4 = 8, then 4 + 5 is one more than 8, which is 9
  3. We can double the larger addend and subtract 1 If 5 + 5 = 10, then 4 + 5 is one less than 10, which is 9

Keywords

  • Double/ Doubling - To become twice as many.

  • Near-double - A near-double is a number close to a double.

Common misconception

Children could try to apply this idea to other near-double facts that may be more easily solved using other strategies.

0 + 1 and 1 + 2 are near-doubles, but these are more easily solved using the 'one more'/ 'one less' strategy. Explore this together before leading children to the most efficient strategy for calculating.

Note, 2 + 3 (and 3 + 2) has been covered in 'adding two', but some may find it easier to relate this fact to 'near double two' rather than the 'odd number after' 3
