Overview

In this interactive activity, students will be led through steps to estimate numbers by rounding in order to make problems easier to solve. There are teaching activities as well as practice activities available. A handout that reviews the strategies taught during the activity can be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.

Mathematics (2019) Grade(s): 3

MA19.3.8

Determine and justify solutions for two-step word problems using the four operations and write an equation with a letter standing for the unknown quantity. Determine reasonableness of answers using number sense, context, mental computation, and estimation strategies including rounding.

UP:MA19.3.8

Vocabulary

  • Unknown quantity
  • Mental computation
  • Estimation
  • Variable
  • Reasonableness
  • Rounding
  • Expression
  • Equation

Knowledge

Students know:
  • Characteristics of addition, subtraction, multiplication, and division.
  • Strategies for addition, subtraction, multiplication, and division.
  • Strategies for mental computation and estimating sums, differences, products, and quotients.

Skills

Students are able to:
  • Use a variety of strategies to solve two-step word problems involving all four operations.
  • Write an equation to represent the problem context, and use a symbol for the unknown quantity.
  • Justify strategy and solutions using mathematical vocabulary.
  • Determine and justify reasonableness of solutions using mental computation strategies and estimation strategies.

Understanding

Students understand that:
  • Mathematical problems can be solved using a variety of strategies, models, and representations.
  • Contextual situations represented by multiplication and division.
  • Reasonableness of solutions can be evaluated by using estimation strategies.
Mathematics (2019) Grade(s): 4

MA19.4.3

Determine and justify solutions for multi-step word problems, including problems where remainders must be interpreted.

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.
Mathematics (2019) Grade(s): 4

MA19.4.9

Round multi-digit whole numbers to any place using place value understanding.

UP:MA19.4.9

Vocabulary

  • Round
  • Place value
  • Ones
  • Tens
  • Hundreds
  • Thousands
  • Ten thousands
  • Approximately
  • Halfway point

Knowledge

Students know:
  • The relationship among positions of digits in a number and place value. They can use that knowledge to round numbers to nay place.

Skills

Students are able to:
  • Use place value strategies to round multi-digit whole numbers to any place.

Understanding

Students understand that:
  • rounding multi-digit numbers is an estimation strategy used when writing the original number as the closest multiple of a power of 10.
