**68. GUESS AND CHECK**

*(*Writing)

**Description:**This is a problem-solving strategy used to solve mathematical problems by guessing, using prior knowledge.

**Application:**Use Guess and Check when students need a starting point to solve problems.

**Process:**Before using this strategy, rehearse with a simple mathematical problem. Ask probing questions such as “what is it that we are looking for in the problem”; “what are the relationships amongst the things in the problem;” and “what operations are being used in the problem?” Direct the students to make a plan by drawing a chart in order to see the relationship between the pieces of the problem. Tell them to “guess” some numbers, completing the chart as directed. Ask students to name or explain shortcuts they use to find the answer and remind them that the charts will help scaffold and organize the information. Require students to review their work by double-checking answers.
