Demonstrate an understanding of division through the development and application of divisibility strategies for 2, 3, 4, 5, 6, 8, 9, and 10, and through an analysis of division involving zero.
[C, CN, ME,R]
| (a) |
Investigate division by 2, 3, 4, 5, 6, 8, 9, or 10 and generalize strategies for determining divisibility by those numbers. |
| (b) |
Apply strategies for determining divisibility to sort a set of numbers in Venn or Carroll diagrams. |
| (c) |
Determine or validate the factors of a number by applying strategies for divisibility. |
| (d) |
Explain the result of dividing a quantity of zero by a non-zero quantity. |
| (e) |
Explain (by generalizing patterns, analogies, and mathematical reasoning) why division of non-zero quantities by zero is not defined. |
