✓Adaptive Reasoning
Essential Understandings Being able to compute fluently means making smart choices about which tools to use and when to use them.
✓Productive Disposition
Numbers can be represented in multiple ways.
✓Conceptual Understanding
✓Strategic Competence
✓Procedural Fluency
The same operations can be applied in problem situations that seem quite different from another. Knowing the reasonableness of an answer comes from using good number sense and estimation strategies. Key Knowledge The operation of division is used to: • find how many of portions of one quantity is in another quantity. • to share equally • repeated subtraction Asking 8 ÷
1 = 8 × 2 since it takes two groups of one-half of a unit to make a whole 2
unit. Examples: 1 8 ÷ = 8 × 2 since it takes 2 one-half's to make a whole 2 3 4 8 ÷ = 8 × since it takes four-thirds of three-fourths of a unit to make one 4 3 whole unit. Key Questions When does a situation call for division? How is dividing related to multiplying? Why is knowing what the “whole” is important?
Key Skills I can recognize when a situation calls for the use of division. I can represent dividing whole numbers and fractions using multiple representations. I can divide whole numbers and fractions with fluency. After Teaching Adaptive Reasoning • Strategic Competence • Productive Disposition • Procedural Fluency • Conceptual Understanding
