Mental Math Units: the Complete Addition Collection
Doubles are some of the most important facts to memorize. Fortunately, they are also often the easiest for students. Doubles occur all around us in real life, for example our fingers and toes are doubles (5 + 5), egg cartons are arranged in doubles (6 + 6), and the wheels on a vehicle are arranged in doubles (2 + 2).
When students know their doubles, they are more easily able to use mental math to calculate near doubles.
This unit includes everything you need to teach the mental math strategy of 'doubles,' including independent/partner based learning activities, a math center, whole-class kinesthetic learning activities and much more! Not only will students work with doubles equations such as 4+4 and 6+6, but they will also learn how to use the doubles strategy for addends that differ by two such as 5+7 and 2+4.
