In this interactive activity, students will be led through steps to solve problems that have more than one operation. There are teaching activities as well as practice activities available. A handout that reviews the steps taught during the activity can be printed. A karaoke song with printable lyrics will help students learn and review the steps taught during the activity. After utilizing this resource, the students can complete the short quiz to assess their understanding.

Unpacked Content

Evidence Of Student Attainment:

Students: When given multi step word problems,

Solve a variety of multistep word problems involving all four operations on whole numbers including problems where remainders must be interpreted.

Explain and justify solutions using connections between the problem and related equations involving a single (letter) unknown.

Evaluate the reasonableness of solutions using estimation strategies.

Note: Multi step problems must have at least 3 steps.

Teacher 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.

Diverse Learning Needs:

Essential Skills:

Learning Objectives: M.4.3.1: Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
M.4.3.2: Solve single-step word problems.
M.4.3.3: Recognize key terms to solve word problems. Examples: in all, how much, how many, in each.
M.4.3.4: Solve division problems without remainders.
M.4.3.5: Recall basic addition, subtraction, and multiplication facts.

Prior Knowledge Skills:

Demonstrate computational understanding of multiplication and division by solving authentic problems with multiple representations using drawings, words, and/or numbers.

Identify key vocabulary words to solve multiplication and division word problems. Examples: times, every, at this rate, each, per, equal/equally, in all, total.

Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Recall basic multiplication facts.

Add and subtract within 20.

Represent repeated addition, subtraction, and equal groups using manipulatives.

Distinguish between rows and columns.

Use repeated addition to solve problems with multiple addends.

Count forward in multiples from a given number. Examples: 3, 6, 9, 12; 4, 8, 12, 16.

Recall doubles addition facts.

Model written method for composing equations.
