Doubles and Near Doubles

        What are doubles facts?? A double is an addition fact where both numbers being added together are the same, like 2+2 or 5+5. Memorizing your doubles facts can help you to add other number sentences more easily. If you know that 3+3=6,  when you see 3+4, you can see that it should be just one more, because four is just one more than 3, so you can take the sum of the double (3+3=6) and add 1 more (3+4=7).  We have introduced the concepts of doubles and near-doubles to our students and we will be continuing to practice addition using doubles in the next few weeks. Here are some resources to help your child practice their doubles.
        We have been singing the doubles rap to help us memorize our doubles facts:

0+0=0: Oh!

1+1=2: Ooh!

2+2=4: More!

3+3=6: Kicks!

4+4=8: Great!

5+5=10: Again!

6+6=12: That’s swell!

7+7=14: Let’s lean!

8+8=16: You’re a queen!

9+9=18: Jelly bean!

10+10=20: That’s plenty!
