Question

Which strategies can be used when dividing? Choose all answers that are correct. A. base-10 block models B. repeated subtraction C. standard division algorithm D. comparing groups

Answer 1

All of the above are possible strategies for division.

_____

Of course, it depends on what you mean by this short description in each case.

One of your other questions involved division using base-10 blocks, so we know that can be a strategy.

Division is often referred to as "repeated subtraction". In fact, the "standard division algorithm" tends toward just that. That is, you could say 6 - 3×2 is repeated subtraction of 3 (or 2, depending on how you look at it).

Obviously, the "standard division algorithm" is a strategy for division.

When dividing cookie dough, you might compare sizes of balls of dough, taking some from the larger ball and adding it to the smaller ball. That is, you would be "comparing groups."
