Double, Double, Double

Recently, we started working on doubles addition facts in math, but practicing these addition facts are embedded in other content areas.  Randomly throughout the day, I'll say, "Double 6."  The students get excited for their turn at answering a doubles fact.  We have talked at length about how important it is to have our doubles facts as automatic knowledge.  When asked a double, we need students to be able to say the answer within a few seconds. We've also started discussing near doubles (ex. 2+3).  Finding the sums to near doubles is much easier when students have the double memorized.  To find the sum to a near double, first double the smaller number and then add one more.  Below are some links to "games" that help students practice doubles and near doubles facts.
