While well-intentioned, these mnemonic frameworks often inadvertently bypass actual mathematical thinking. When a student learns that "altogether" means add or "left over" means subtract, they aren't solving a problem—they are performing keyword substitution. The moment a problem introduces a subtle twist, the checklist breaks down, leaving students feeling helpless and stranded.
Moving beyond checklists requires shifting our goal from getting students to complete a task to helping them develop genuine problem-solving capacity.
Keyword strategies create a false sense of security. Consider this classic example:
"Maya has 12 stickers. She has 4 more stickers than Leo. How many stickers does Leo have?"
A student trained on word-problem checklists immediately spots the word "more" and adds the two numbers to get 16. The checklist worked as designed, but the reasoning failed completely. Real problem-solving requires students to visualize relationships, not scan for linguistic shortcuts.
So let's look at four strategies that build authentic problem solvers. It means moving past formulaic steps to encourage flexible, adaptable thinking.
1. Launch Tasks with "Notice and Wonder" Before handing students a question to calculate, strip the actual question and numbers away. Present a situation—such as "A store is holding a sale on three types of apples"—and ask students two simple questions: What do you notice? What do you wonder? This forces learners to sense-make the context and construct meaning before jumping into calculations.
2. Standardize Visual Representation Instead of hunting for procedural keywords, train students to map out the structure of a problem visually. Tools like bar models or tape diagrams help students visualize relationships between quantities:
Are we joining two parts to make a whole?
Are we comparing two unequal quantities?
Are we splitting a total into equal groups?
Once a student can represent the relationship visually, choosing the correct operation becomes intuitive rather than guesswork.
3. Shift to Collaborative, Vertical Spaces Inspired by Peter Liljedahl’s Building Thinking Classrooms, shift students away from isolated desks and paper worksheets. Having students work in small, randomly assigned groups at vertical non-permanent surfaces (like dry-erase boards) encourages risk-taking and active dialogue.
4. Ask "Keep-Thinking" Questions When a student gets stuck, the instinct is often to offer a hint that reveals the next step. Instead, offer prompts that keep the thinking on the student:
"What do you know so far that isn't written in numbers?"
"Can you draw what is happening in this scenario?"
"Does your answer make sense in the real world?"
Summed up, the primary goal is to find the correct answer by understanding mathematical relationships. Students need to scan for action words and verbs by visualizing, discussing, and modeling. These two things should lead to flexible reasoning paired with resilience. Teaching students to solve problems isn't about giving them a blueprint for every scenario—it's about building their confidence to navigate unfamiliar territory when there isn't a blueprint at all.
