JBDad, I think you're running into the multiplication conundrum. In Rightstart math for ex: 5x3 is translated to 5 taken 3 times ie 5, 10, 15 (5+5+5).
In Everyday math, 5x3 is 5 sets of 3, ie 3 taken 5 times or 3, 6, 9 ,12, 15, (3+3+3+3+3).
In Singapore math, 4x3 is represented as 4 groups of 3 rabbits ie 3 taken 4 times or 3,6,9, 12.
Whenever I bring this up, people say "but the commutative property!!" But in EM or RS for example, if they ask for an array to demonstrate 5x3, only one answer is given.
