On the odd numbered days in September when a “neighbor ” or ” double plus one” fact appears, children may need help seeing the more familiar double within. For example, on September 15th, when looking at 8+7 or 7+8, we can ask, ” What was the double before we added one more? ” When children recognize the “double” within each “double plus one” fact, they can use the easier “double” fact and just add one more to find the sums for harder facts like 5+6, 6+7, 7+8, and 8+9.

Other Strategies : When looking at the double ten grids, some students may suggest other ways of working with 8 and 7 to get 15. Some may suggest taking two from the seven to give to the 8, making the 8 into a full ten with five left to make 15. Others may suggest “pulling out five” from 8 and from 7 to make ten, and adding on the leftover 3 and 2 to make 15. It is exciting when children begin to develop this “friendliness with numbers”, to quote Bob Wirtz. He promoted the use of ten grids to foster number sense and fact mastery over 30 years ago.
