The basic four-step problem-solving procedure includes: (1) Understand the problem, (2) Devise a plan, (3) Carry out the plan, and (4) Look back and check. Understand the problem: This step is important because students need to clearly know what is being asked before trying to solve anything. Devise a plan: Creating a strategy is necessary so students have a clear path to finding the solution. Carry out the plan: This is where students put their strategy into action. Look back and check: Reflecting helps students confirm their solution and learn from mistakes. Example problem: Sarah has 3 packs of stickers. Each pack has 8 stickers. How many stickers does she have in total? Using the four steps: 1. Understand: We need to find the total number of stickers. 2. Plan: Multiply the number of packs by the number of stickers per pack (3 8). 3. Carry out: 3 8 = 24 stickers. 4. Look back: Check by using addition: 8 + 8 + 8 = 24 stickers. The answer makes sense. Teaching it in the classroom: I would model each step on the board with a different color, thinking aloud so students hear my process. Then students would work with a partner to practice the steps on new problems
