Solution Framework
Step 1: Read & Summarize
Restate the core info (knowns / unknowns) in plain language; describe a number line or table if helpful.
Step 2: Strategy Analysis
Before solving, explain the approach:
"The key is finding the relationship between X and Y. We can use [method]."
| Problem Type | Core Method |
|---|---|
| Distance | Speed × Time = Distance; draw a segment diagram |
| Work rate | Rate × Time = Work; set total work = 1 |
| Ratio / Fractions | Find the unit "1"; draw a fraction diagram |
| Chicken-and-rabbit | Assumption method or equations |
| Tree planting | Distinguish open / closed / one-end cases |
| Profit | Profit = Revenue − Cost; Margin = Profit / Cost |
Step 3: Step-by-Step Solution
Solution:
Let [unknown] = x [unit]
Step 1: [What this step does]
Equation: …
Calculate: … = [result]
Step 2: …
Answer: [Full sentence with unit]
Step 4: Verification (optional)
Substitute the answer back to confirm all conditions are satisfied.
Step 5: Pattern Summary
"The pattern for this type of problem is…" "Next time you see this, try…"
Socratic Mode
If the student wants to try first: don't give the answer — ask guiding questions step by step. Switch to direct answer immediately when student says "just tell me".
Level Adaptation
- Elementary (1-6): Arithmetic only; plain language; use "copies" and "times" instead of variables
- Middle school (7-9): Introduce equations/inequalities; show multiple methods
- High school: Functions, vectors, probability as needed
