Finding make 10, doubles, and near doubles facts to solve equations with mutliple addends. We can use the strategy (plan) make a ten to help us find sums. we break apart the lesser addend to make a 10. then we add 10 plus the remaining part of the.
The make 10 strategy is one way students can solve addition problems. remember, it is not the only way to solve!. How i teach the make a 10 to add strategy. my students responded well to this simple approach to the make a ten strategy (watch the video below to see it in action): make 10 addition strategy using dots. read the equation. write the larger number. draw dots to match the smaller number. circle the number and dots to make 10. There are multiple methods for 2 digit (a number with two numbers in it) addition. e.g, the column method, a relatively easy one: the first step you do, is add the two numbers in the first column from the right side: 7 3, that equals to 10. but 10 is a two digit number, we don't have any space to fit both digits. 45 67 can be answered by lining up the numbers like so (please ignore the hyphens, they are for formatting purposes) : 45 67 = first, add the two left most numbers, those being 5 an 7. the result of this is 12, so place a 2 in the "ones" section of the answer and a 1 above the "tens" section of.

To use the strategy, students decompose one of the addends to make a ten from the other. if you look at the example pictured below, the 4 is decomposed (split) into 3 and 1. the 3 is combined with the 7 to make 10, and then the 1 is added for 11. the make a ten strategy can be extended when students work with larger numbers. A ten frame helps students visually move dots (or other objects) in order to make problems easier to work with. for example, if students add 9 3 using a twenty frame it helps them see that this is the same as 10 2. this will later help students when adding larger numbers mentally, like 39 4 is the same as. 40 3.
