Maths word problems are where mathematics meets the real world. They require learners to read a scenario, identify the relevant information, choose the correct mathematical operation, and calculate the answer. For many South African learners, word problems are the most challenging part of maths — not because the calculations are harder, but because the translation from words to numbers is a skill that needs to be explicitly developed. This guide covers both the teaching side and the learning side of word problems.
Selecting Quality Word Problems
Not all word problems are equal. The best word problems are relevant to your child's life, appropriately challenging for their level, and connected to concepts they are currently learning. Problems that are too abstract or too easy do not build skill.
Choose problems that require genuine thinking rather than simple plug-and-play calculation. Good problems often have multiple entry points, allow for different solution strategies, and connect to real South African contexts — shopping, cooking, sport statistics, travel distances.
Fostering Conceptual Understanding
Before jumping into solution techniques, make sure your child understands the mathematical concept behind the word problem. If a child does not truly understand what multiplication means in context, no amount of keyword-spotting will help them solve multiplication word problems reliably.
Use physical objects, diagrams, and real-life demonstrations to build conceptual understanding. If the problem involves fractions, cut an actual pizza. If it involves measurement, take out a ruler or tape measure. Concrete understanding must come before abstract problem-solving.
Enhancing Collaboration
Word problems are excellent for group work because they generate discussion about different approaches. When children talk through their reasoning, they strengthen their own understanding and learn from each other's strategies.
Encourage your child to solve word problems with a sibling, friend, or study partner. After each problem, compare strategies: "How did you approach it? Did we get the same answer? Why or why not?" This collaborative approach builds both mathematical reasoning and communication skills.
Guiding Through Effective Feedback
When checking your child's word problem answers, focus on the process rather than just whether the final answer is correct. If the answer is wrong, identify where the error occurred — was it in reading the problem, choosing the operation, setting up the equation, or the calculation itself?
Ask guiding questions rather than simply correcting: "What did the problem ask you to find?" "How did you decide to use multiplication?" "Does your answer make sense in this situation?" This type of feedback builds self-correction skills that transfer to exam situations where you are not there to help.
Making Word Problems a Daily Habit
Like any skill, word problem ability improves with regular practice. Work through one or two word problems daily rather than doing a large batch once a week. Create word problems from everyday situations: "If electricity costs R2.50 per kWh and we used 480 kWh this month, what is the electricity bill before VAT?" Ask your child to write their own word problems for family members — creating problems deepens understanding even more than solving them.
A Step-by-Step Guide to Solving Word Problems
This five-step process works for word problems at any level, from Grade 1 addition to Grade 12 calculus applications.
Step 1: Survey the Problem
Read the entire problem through once without trying to solve it. What is the story about? What information is given? What is being asked? On the second read, underline key numbers and circle the question being asked. Identify any unnecessary information that is there to distract.
Step 2: Break It into Parts
Many word problems involve multiple steps. Identify each step before trying to calculate anything. For example, a problem might require you to first calculate a total and then find a percentage of that total. List the steps in order before starting the calculations.
Step 3: Work Through One Step at a Time
Solve each step separately and write down your working clearly. This earns method marks in CAPS and IEB exams even if the final answer is incorrect. Do not try to do multiple steps in your head — write everything out.
Step 4: Know Where to Find Help
If your child gets stuck, teach them strategies for getting unstuck: draw a diagram, try a simpler version of the problem, work backwards from the answer, or look for a similar problem they have solved before. Platforms like iRainbow provide grade-appropriate word problems with worked solutions that show each step.
Step 5: Check Your Results
After solving, ask: "Does this answer make sense?" If the problem asks how many sweets each child receives and the answer is 3.7, something has gone wrong. Estimate the answer before calculating to give yourself a benchmark. If your calculated answer is wildly different from your estimate, recheck your work.
Strategy 1: The CUBES Approach
CUBES is a structured approach that gives learners a consistent process for attacking any word problem. Each letter represents a step.
C — Circle the key numbers. U — Underline the question being asked. B — Box any action words (total, difference, each, shared, remaining). E — Evaluate what operations are needed. S — Solve and check your answer.
CUBES Example
Problem: "A school has 342 learners. If 156 are boys, how many are girls?" Circle: 342 and 156. Underline: "how many are girls?" Box: "how many" (indicates subtraction of a part from the whole). Evaluate: 342 minus 156. Solve: 342 - 156 = 186 girls. Check: 186 + 156 = 342. Correct.
Strategy 2: The RUNS Approach
RUNS is another structured method that works well for multi-step problems.
R — Read the problem twice (once for understanding, once for detail). U — Underline important information and the question. N — Number the steps you need to take. S — Solve each step and show your working.
RUNS Example
Problem: "Sipho earns R150 per hour and works 8 hours on Saturday and 5 hours on Sunday. How much does he earn for the weekend?" Read twice. Underline: R150 per hour, 8 hours Saturday, 5 hours Sunday, weekend total. Number the steps: (1) Calculate Saturday earnings, (2) Calculate Sunday earnings, (3) Add both days. Solve: Saturday = R150 x 8 = R1,200. Sunday = R150 x 5 = R750. Weekend = R1,200 + R750 = R1,950.
