Counting on from the larger number is an early addition strategy, and builds on the earlier strategy of Counting On. When students count on from the larger number they demonstrate an understanding of the Commutative Property of addition, where the addends can be switched around to reduce the amount of counting needed. If a student used this strategy to solve 3 + 5 the student would switch the addends to show 5 + 3. The student might say “five”, hold up three fingers and then count on, “6, 7, 8”. They may model the counting by moving or putting down their fingers as they count.
To support students learning to count on from the larger number, provide direct instruction on the commutative property of addition where a pair of numbers can be switched around to reduce the amount of counting required, without changing the result. Consider math talks with the whole class or small groups, focused on how two equations are the same and how they are different (e.g., show the group 2+6=8 and 6+2=8). Encourage discussion about how the addends in an addition sentence can be switched and you will still get the same sum. Also encourage students to share why it's helpful to start with the larger addend (e.g., it's faster or there is less chance to make a mistake).
During this game, teachers can provide students play with a 100s Chart. Students are encourage to use the strategy counting on from the larger number (using the spinner provided). (Adapted from Lawson, pg. 164 - modified)
