UP:MA19.4.3
Vocabulary
- Operation
- Multi Step problem
- Remainder
- Unknown quantity
- Equation
- Rounding
- Mental strategy
- Partition
- Estimation
- Reasonableness
Knowledge
Students know:
- Context situations represented by the four operations.
- How to calculate sums, differences, products, and quotients.
- Estimation strategies to justify solutions as reasonable.
Skills
Students are able to:
- Solve multi-step word situations using the four operations.
- Represent quantities and operations physically, pictorially, or symbolically.
- Write equations to represent the word problem and use symbols to represent unknown quantities.
- Use context and reasoning to interpret remainders.
- Use estimation strategies to assess reasonableness of answers by comparing actual answers to estimates.
Understanding
Students understand that:
- Using problem solving strategies will help them determine which operation to use to solve a problem.
- Remainders must be interpreted based on the context, and remainders are sometimes ignored, rounded up, or partitioned.
