Word Problems - Cubes Strategy: Step-by-Step Guide
💡Taking notes during lectures shouldn’t feel like a race. Lumie’s Live Note Taker captures and organizes everything in real time, so you can focus on actually learning.
Students who get stuck on word problems often need one clear routine to follow. The word problems - cubes strategy is a simple, five-part checklist that helps you slow down, parse the text, and avoid common keyword traps. Early on, tools like Lumie AI can help you convert notes and classroom examples into practice flashcards or quick summaries so you can practice the CUBES routine more consistently.
word problems - cubes strategy: How do I use the CUBES method step-by-step?
Start by remembering what each letter in CUBES stands for: Circle, Underline, Box, Evaluate, Solve (and Show). Using a consistent five-step approach reduces mistakes from rushing and helps you break complex language into math you can calculate.
Step 1 — Circle the numbers
Circle every number in the problem, including those that show up in units (like 3 kg or 2/5). This helps you see all values before deciding which operation to use; sometimes a number is part of extra information or a later step.
Step 2 — Underline the question
Underline exactly what the problem asks you to find. Students often compute something related but not what’s requested; underlining keeps your answer focused and avoids wasted work.
Step 3 — Box key words
Box or highlight operation clues and relation words like “total,” “difference,” “each,” “per,” or “altogether.” Remember that keywords can be deceptive — they’re hints, not rules — so box them and then confirm with the context.
Step 4 — Evaluate what the problem is asking
Ask yourself: is this single-step or multi-step? Which operations connect the circled numbers? Estimating the rough answer helps catch errors early before you do detailed calculations.
Step 5 — Solve and show your work
Write the equation(s) clearly, solve, and then check your units and whether your answer actually answers the underlined question. Showing work makes it easier to find and fix mistakes later.
Many teachers provide printable CUBES templates and anchor charts to practice these steps in class or at home (Differentiated Teaching CUBES guide). Using a template for a few weeks builds the habit until the steps become automatic.
word problems - cubes strategy: Is CUBES better than other word problem systems?
Students often compare CUBES to strategies like RUCSAC, KWL, or keyword-only methods. CUBES is compact and highly visual, which makes it a fast routine for elementary and middle-school problems. That said, no single strategy is perfect for every problem type.
Strengths of CUBES
CUBES forces attention to numbers, the question, and contextual clues in a repeatable order. That reduces the tendency to jump to an operation based only on a single keyword.
Where other methods shine
More detailed frameworks (like RUCSAC) add steps for rechecking or planning multi-step solutions, which can be helpful for older students tackling algebra or multi-step tasks. For advanced problems, pairing CUBES with a planning step works well (Maneuvering the Middle problem-solving strategies).
word problems - cubes strategy: Where can I get printable templates and worksheets?
Teachers and students look for ready-made CUBES graphic organizers to use with homework and timed practice. Printable sheets help you practice the routine until it feels natural during tests.
Free and editable resources
There are many free CUBES worksheets and teacher-created anchor charts online you can print or edit for different grade levels. These templates often include space to circle numbers, underline the question, and write the boxed keywords so students can physically follow the routine (Teachers Pay Teachers search results for CUBES worksheets).
How to use a worksheet effectively
Use a CUBES worksheet as a daily warm-up or exit ticket. Time yourself occasionally to get comfortable using the steps under pressure. After you finish, compare your work with a peer or a teacher to learn alternate ways to box keywords or set up equations.
word problems - cubes strategy: How do I apply CUBES to multi-step and challenging problems?
CUBES works well for multi-step problems if you expand the Evaluate and Solve steps into sub-steps. The habit of breaking down the problem helps with algebra and real-world multi-stage scenarios.
Tackle one step at a time
For multi-step tasks, after Evaluate, write sub-goals: Step A, Step B, etc., and mark which circled numbers belong to each sub-goal. This keeps work organized and reduces errors from mixing quantities.
Example: Two-step practical problem
If a problem asks how many total pages two friends read over two weeks, circle all page numbers and weeks, underline “total pages,” and then box words that show grouping or adding. Solve the first part (pages per week per friend) then the second (total pages), checking units each time.
Teachers and curriculum writers often show how to scaffold CUBES from single-step to multi-step problems to support gradual skill growth (Jillian Starr teaching CUBES strategy).
word problems - cubes strategy: What are common mistakes and limitations of CUBES?
Students can over-rely on keywords or treat CUBES like magic: circle something, pick an operation, and get it right. That misunderstanding leads to mistakes on trickier problems.
Common pitfalls
Treating boxed keywords as absolute (e.g., assuming “more” always means “add”). Context matters and the same keyword can imply different operations depending on the sentence.
Missing implied quantities or units not expressed as numbers (like “a dozen” or “half the class”). Always translate words into numbers if needed.
Rushing through the Evaluate step. If you skip evaluating, you may combine unrelated numbers or choose the wrong operation.
When CUBES doesn’t fit perfectly
Very abstract algebra word problems or non-numeric logic puzzles may need other strategies or a planning step before CUBES. Use CUBES as part of a toolkit, not as the only tool; alternative strategies are available for higher-level reasoning (NoteGPT guide to solving word problems using CUBE).
word problems - cubes strategy: How can I use CUBES for test prep and timed exams?
Practice CUBES under timed conditions to build speed without sacrificing accuracy. The routine reduces the time spent re-reading by forcing you to mark the problem methodically.
Timed practice tips
Use a mix of single- and multi-step problems in 15–20 minute drills. Start by focusing on accuracy for the first sessions, then shave seconds off each step as you repeat the routine.
Exam-day checklist
On test day, quickly circle numbers and underline the question before doing any mental math. If a problem feels like it will take too long, mark it and come back — CUBES helps you triage problems efficiently during a test.
word problems - cubes strategy: Are there digital tools or AI that help practice CUBES?
Students increasingly want tech that gives instant feedback and adapts practice to their mistakes. Digital tools can automatically parse word problems and show how CUBES would mark them up.
What to look for in a tool
Choose tools that let you upload problems (or take photos), then highlight numbers, underline questions, and prompt you to choose operations. The best tools provide step-by-step feedback and practice quizzes to target weak steps.
Try AI-enabled practice and flashcards
A smart study assistant can turn class notes or homework problems into targeted practice sets. For example, the AI Flashcard Generator from Lumie AI can convert solved word-problem examples into quick flashcards so you can drill specific CUBES steps you find tricky. Combining digital practice with printable worksheets helps transfer routine from practice to assessment.
