A double is a number added to itself, like 6 + 6 = 12. Children usually learn doubles early because they are easy to say and to picture. Near doubles use that knowledge to solve harder facts: 6 + 7 is one more than 6 + 6, and 5 + 6 is one less than 6 + 6. This worksheet mixes doubles with near doubles, eighteen facts on one page, so your child has to look at each fact and notice whether the two numbers are the same or one apart.
A grey example at the top of the page shows the thinking in a chain. Ask your child to say the double they know first, then say how much more is left to add, and write the sum on the line.
What your child will learn
Recall doubles up to 15 + 15
Find a near double by adding one or two to a double
Say the strategy out loud before writing the sum
Common Core standard: 2.OA.B.2
Worked example
For 3 + 4, the double 3 + 3 is 6, and one more is 7. So 3 + 4 = 3 + 3 + 1 = 6 + 1 = 7.
Common mistake
Adding the double correctly and forgetting to add the extra one or two.
