Mental Math Addition Strategies

1. Counting On – Counting On is generally the first mental math strategy that should be taught, as it is the easiest for most students. Chances are that some or many of your students are already using this strategy without knowing it. Counting on means that you start with the biggest number in an equation, and then count up. For example, in the equation 5+3, you want students to start with the “5” in their heads, and then count up, “6, 7, 8.” This is to discourage students from counting like, “1, 2, 3, 4, 5…..6, 7, 8.” Students also need to be taught that if an equation looks like this: “2+6,” they still should start with the bigger number in this case “6” and count up “7, 8.”

Counting On is a beginning mental math strategy for addition. It is generally taught as an introductory mental math strategy and is usually very easy for students to grasp. The chances are good that some or many of your students are already using this strategy without knowing it.

Counting on means that you start with the biggest number in an equation, and then count up from there. For example, to add 5+3, you want students to start with the “5” in their heads, and then count up, “6, 7, 8.” This is to discourage students from counting like this: “1, 2, 3, 4, 5…..6, 7, 8.”

What is counting on?

Counting on is where you start with the larger number of the two numbers and count on the smaller number. This is much more efficient than beginning with the smaller number and counting on. For example: 4 + 7 =

Start with the larger number (7) and then get your students to count on 4: 8, 9, 10, 11. You could get your students to use counters, their fingers or a number line/track. Get students to first circle the larger number and then count on. You could also complete counting on using a 100 chart.
