These doubles plus two worksheets tackle the trickiest near-doubles for older students—I’ve watched 2nd and 3rd graders who could handle 10+10 and even 10+11 get completely stuck when they hit 10+12, but these activities break down that mental barrier beautifully. The ten frame activities let kids physically see how two more dots changes everything, and the themed worksheets keep them engaged when the concept gets challenging. Perfect for those moments when students need to bridge from concrete counting to mental math, and the progressive difficulty ensures they’re building real understanding, not just memorizing patterns. Whether you’re working with struggling learners or pushing advanced students, these worksheets give everyone the foundation they need for more complex addition strategies.
