(03) Integers 3: Multiply and Divide within 100
Topic outline
-
Essential Questions
- How do multiplication and division and multiplication help us solve problems? What types of problems?
- How can we represent our thinking about multiplication and division?
- How are multiplication, division, addition, and subtraction all related? How do we know when to use each?
- How can we use one multiplication fact to determine another?
- How can we use one division fact to determine another?
- Which multiplication and division facts should be memorized? And when is it OK or better to estimate or use a strategy or a calculator?

I will..
- Play the Factor Game.
- Play Last to Zero.
- Do Leveled Drills for Remainders
- Drill solving and representing remainders in groups, rows, and jump situations. [Under construction.]
- Do JUMP Mult & Div Review, with Remainders
- Learn to use the words "multiple" and "factor" and how they relate to remainders and divisibility. I'll be able to describe all the divisibility rules and create examples to show them.
So I can...
- Explain and demonstrate with my own examples when and why remainders occur, what they are, and how to interpret them in context for all previous representation.
- Explain my reasoning using the words “multiple” and “factor”.
- Use equations to record my thinking about remainders.

2.9.2 Students will be fluent in solving division equations with and without remainders (15 solutions per minute, 95% accuracy, can do orally as teacher or tutor writes). Remainder Drills - Division Only
2.9.3 Students will be fluent in solving equations involving remainders and determine a corresponding multiplication or division statement. Example: \( 7 \div 2 = 3\ R1 \iff 2 \times 3 + 1 = 7 \)
2.9.4 Students will be able to generate examples of all of the above.

So I can...
- Count by 2, 5, and 10 up to 10 groups, without reference to ones. I use automatic recall or addition strategies instead.
- Show my thinking with manipulatives, number tracks and/or number lines, aloud, and in written sequences and tables.
- Use skip counting to solve equations and I always pick the easier skip count when possible.
