Number Bonds Visualizer
Explore how a whole breaks into two parts with symbolic chips or ten-frame counters, plus missing-part practice for fluency.
Doubles & Near Doubles
Show the doubles-based strategy for addition facts. Students see how to anchor on a known double and adjust by one or two with symbols and ten-frames.
Multiplication Array Maker
Build a solid foundation for multiplication. Students see each fact as a rectangle of dots on a 10 × 10 grid — turning abstract multiplication into something they can see and understand.
Teacher tip: Start with concrete visuals, then switch to symbolic form. These tools are designed so students can see the same idea in multiple representations without changing context.
