These bite-sized lessons are an excellent, well-structured resource for teaching problem-solving skills in a clear and engaging way. The slides are visually appealing, easy to follow, and perfectly aligned with first-grade learning goals. I appreciate how the lesson explicitly models strategies for 2-digit addition. The gradual progression and student-friendly language help build confidence, especially for learners who find operations challenging.

This resource was exactly what I needed for teaching open number lines in first grade! The visuals are clear and easy for young learners to understand, and the progression from guided to independent practice helped my students gain confidence quickly. The activities really supported their understanding of how numbers relate to one another, not just how to “get the answer.” I loved that it included both addition and subtraction—great for reinforcing the connection between the two! Definitely a go-to math center and small group tool.
