Adding Doubles Plus 2: what children learn
"Doubles plus 2" facts (like 6 + 8) sit two steps past a memorized doubles fact — 6 + 8 is double-6 (12) plus two more, the same shortcut idea as doubles-plus-1 applied one step further.
Adding Doubles Plus 2: worked example
6 + 8 = 14
6 + 8 is two more than the doubles fact 6 + 6 = 12, so 6 + 8 = 12 + 2 = 14.
Adding Doubles Plus 2: a common mistake to watch for
Kids sometimes mix this up with doubles-plus-1 and add only one extra instead of two — checking the actual gap between the two numbers first avoids the mix-up.
Adding Doubles Plus 2: how to help at home or in class
Stack two towers of blocks, one two taller than the other. Ask your child to knock the extra two blocks off, double what remains, and then put the two blocks back. Compare this with towers that are only one apart. Play a toss game with two dice that land two apart. Your child is ready to move on when they can pick the right shortcut by looking at the gap between the two numbers.
