Make 10 Strategy
Teach bridging through 10 with step-by-step ten-frame visuals that show decomposition and recomposition.
Place Value Exploder
Break numbers into hundreds, tens, and ones using both digit cards and Dienes base-ten block representations.
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.
Distributive Property of Multiplication
Turn hard multiplication facts into easy ones. Students learn the distributive property the textbook way, then use it to break facts apart for mental math.
Times Table Explorer
Make the times table less scary. See any multiplication fact as dots, find its commutative twin, and read each table with skip-counts — as a single table, the full chart, or a low-stakes practice.
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.
