The Doubles Rap

Today our friends practiced “the doubles” addition facts ( 2+2=4, 3+3=6, etc).  We learned a rap that could help us remember the facts quickly without having to clap and count on.   Today your child will be coming home with doubles flashcards to practice at home and they would LOVE to sing the rap for you too :).

We used our doubles facts to help us with facts that are close to doubles too.

Math Update

Today we learned about the doubles strategy when we add or subtract numbers, as well as doubles plus or minus one.  Look for a cool ipod to be coming home this week to practice our doubles facts.  See the example below for how we use the doubles +/- 1 strategy when we add.
