Students learn to add efficiently by building on known doubles. This strategy reduces the number of facts to memorize and strengthens mental math. Once students know their doubles, they can quickly solve any near-double fact.
How Teachers Can Use This Worksheet
- Doubles review: Warm up by reciting doubles (1+1 through 10+10) before introducing plus one.
- Counter model: Show 6 + 6 with counters, add one more, and discuss how 6 + 7 relates.
- Exit ticket: Ask students to solve one near-double and explain the double they used.
How Parents and Homeschoolers Can Use This Worksheet
Practice doubles aloud first (3+3, 4+4, 5+5), then ask "what is 5+6?" and help your child see it as 5+5 plus one. Use small objects to make the +1 visible. Keep sessions short; this strategy clicks quickly once doubles are solid.
