Developing the meaning of multiplication is so important! Congratulations for insisting upon understanding. If only memorizing correct answers, children are likely to have trouble with all future math.
I’m retired now but taught for many years. Please see my four models of multiplication that I taught to my advanced first and second graders. The models promote a comprehension of various ways of understanding multiplication. They loved the exercises and did very well. These models could be used for any age involved in learning multiplication.
I also have models of addition and subtraction, if you’d like them.
