Addition – Mental Methods Did you: Count on from the largest number? Re-order the numbers? Partition the numbers into 100s 10s and ones? Bridge through 10 and multiples of 10? Add 9, 11, etc. by adding a multiple of 10 and compensating? Use near doubles? Use knowledge of number facts? These are all strategies that children need to be aware of when carrying out addition calculations.
