Today, I will use the doubles strategy and the doubles plus 1 strategy to make easier and known sums.
Vocabulary
Teacher Resources
Doubles fact: an equation where both addends are the same. 2+2=4 Doubles plus one: when you add consecutive numbers, you can use the sum of the double and add one more.
Break apart to make a doubles + 1
2+3= 2+3= 2+3=
2+2+1 4+1 5
Considerations: This strategy is most effective when students have already memorized their doubles facts. If needed as a scaffold, students may use counters to help them solve. Math vocabulary is provided in the Student Journal.
Steps: 1. 2. 3. 4.
Identify the doubles and add + 1. Add the doubles fact. Add one to the doubles fact. Record the sum.
Application of MPs: MP1: Add the doubles
What did you do first?
MP6: How can you use the math vocabulary in your explanation? MP7: Is there another way to see the problem?
