Doubles refers to adding the same number twice, for example 5 5. generally when we refer to the doubles addition facts in elementary math, we are referring to facts from 1 1 to about 12 12. the doubles are not so much a math strategy as a set of facts that students should know. when kids know the doubles, they are able to use them as a building. Knowing their doubles facts is a key component in being able to use a variety of mental math strategies such as doubles plus or minus one, two, or three. if you have never used the doubles strategy before and aren’t sure of how it can help students, consider this: “i know that 10 12 = 22, because i know that 10 10 = 20 so i just add on. The real magic comes with “near doubles facts” or “doubles facts plus one.”. if we know 7 7=14, then when we see 7 8 we know 8 is one more than 7. so one more than 14 is 15. so, the answer is 15. we can also take it with one less than the doubles fact. we know 7 7=14. then when i see 7 6 i know that 6 is one less than 7. so one less.
