Develop the strategy of near double addition, adding one more than double 6, 7, 8, 9.
Prior knowledge of double bonds 6, 7, 8, 9 and the commutative property of addition is needed.
- double bond
- near double
- one more
- addition as “add”
A little easier
Use Bond Blocks organised with part-part-whole to calculate the double, plus one more. For example,
A little harder
Activity 62 near double one less
Develop the near double strategy of subtracting one from double 6, 7, 8, 9.
