Word Problems Study Guide
What are Word Problems?
Word problems are mathematical problems presented in the form of a story or a scenario. They require students to apply their understanding of mathematical concepts to real-life situations.Steps to Solve Word Problems
- Read the problem carefully: Understand the given information and what needs to be solved.
- Identify the key information: Determine what facts and numbers are provided in the problem.
- Choose the correct operation: Decide whether addition, subtraction, multiplication, or division should be used to solve the problem.
- Solve the problem: Perform the necessary calculations to find the solution.
- Check your answer: Verify that the solution makes sense in the context of the problem.
Types of Word Problems
Word problems can involve various mathematical concepts, including:- Addition and Subtraction: Problems involving combining or taking away quantities.
- Multiplication and Division: Problems requiring the use of multiplication or division to solve.
- Fraction and Decimals: Problems dealing with parts of a whole or parts of a set.
- Measurement: Problems related to length, weight, time, and other units of measurement.
- Money: Problems involving calculations with currency and finances.
Tips for Solving Word Problems
- Translate into Math: Convert the information in the problem into mathematical expressions or equations.
- Use Visual Aids: Draw diagrams or use models to help understand the problem.
- Look for Keywords: Identify words that indicate which operation to use (e.g., "sum," "difference," "product," "quotient").
- Practice: Solve various types of word problems to build proficiency and confidence.
Sample Word Problem
Timmy has 5 apples. He gives 2 apples to his friend. How many apples does Timmy have now?
Solution:
We start with 5 apples and then subtract 2 apples (since he gives them away).
5 - 2 = 3
Timmy has 3 apples left.

Number and Operations (NCTM)
Compute fluently and make reasonable estimates.
Develop fluency in adding, subtracting, multiplying, and dividing whole numbers.
Select appropriate methods and tools for computing with whole numbers from among mental computation, estimation, calculators, and paper and pencil according to the context and nature of the computation and use the selected method or tools.
Algebra (NCTM)
Represent and analyze mathematical situations and structures using algebraic symbols.
Express mathematical relationships using equations.
Use mathematical models to represent and understand quantitative relationships.
Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.
Grade 4 Curriculum Focal Points (NCTM)
Number and Operations and Algebra: Developing quick recall of multiplication facts and related division facts and fluency with whole number multiplication
Students use understandings of multiplication to develop quick recall of the basic multiplication facts and related division facts. They apply their understanding of models for multiplication (i.e., equal-sized groups, arrays, area models, equal intervals on the number line), place value, and properties of operations (in particular, the distributive property) as they develop, discuss, and use efficient, accurate, and generalizable methods to multiply multi-digit whole numbers. They select appropriate methods and apply them accurately to estimate products or calculate them mentally, depending on the context and numbers involved. They develop fluency with efficient procedures, including the standard algorithm, for multiplying whole numbers, understand why the procedures work (on the basis of place value and properties of operations), and use them to solve problems.
Connections to the Grade 4 Focal Points (NCTM)
Number and Operations: Building on their work in grade 3, students extend their understanding of place value and ways of representing numbers to 100,000 in various contexts. They use estimation in determining the relative sizes of amounts or distances. Students develop understandings of strategies for multi-digit division by using models that represent division as the inverse of multiplication, as partitioning, or as successive subtraction. By working with decimals, students extend their ability to recognize equivalent fractions. Students' earlier work in grade 3 with models of fractions and multiplication and division facts supports their understanding of techniques for generating equivalent fractions and simplifying fractions.
