Our kiddos were having difficulty conceptualizing multiplication and division (with remainders) - physically, when I was a principal. This occurred despite the fact that they had mastered their math facts and were computationally proficient with 2 x 3 multiplication and 2-digit divisor division. Many students did not connect the meaning of the mathematics beyond the algorithm computation. Hence, a simple diagram was developed that worked every single time, so both the physical meaning of larg
