Addition strategies
There are many ways to add: counting on means starting at the bigger number and counting up, like solving 6 + 3 by counting "7, 8, 9"; using number bonds means knowing a number's parts, like knowing 6 is made of 2 and 4, to quickly find related sums such as 2 + 4 = 6; or making a ten, like solving 8 + 5 as 8 + 2 + 3 = 10 + 3 = 13, since 10s are easy to add. Different strategies work better for different problems.
