This is another take on James Tanton’s Exploding dots.

In kindergarten, when students are shown 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and THEN the crowd of students should all looked shocked and say things like “WHOA, what just happened there!!!!” BUT instead this HUGE mathematical idea goes unnoticed. So, this activity will make students ooh and ahhh as they should, as well as deepen their understanding of our base 10 system which is foundational to understanding our number code, addition, subtraction, decimals and more.

A drawing/image based activity to help students understand the relationship between number multiples, prime numbers, prime factors, and division. The image-based puzzles reduce the barrier for those who struggle to memorize while helping them to continue to connect to the meaning of multiplication (whereas using a calculator does not connect to meaning). The idea is that over-time these images are meant to aid the student in memorizing their times tables in a non-stressful way. …

Check out the introduction to the Mathematical Fusion Machine first! The activities within this presentation are meant to help students explore different properties of decimals, the students are to spend time building and experiencing each activity. …
