Guess and Check
|
The skills used to Guess and Check are essential for helping students build mathematical models and write equations. Getting good and guess and check is an important step on the way to algebraic reasoning. In that regard, Guess and Check is closely related to the Make a Table and Make a Mathematical Model strategies. Plus, careful, organized conjecturing and hypothesis testing is at the heart of what mathematicians do. One other thing: when doing guess and check, never erase guesses that didn't work. If you do, how can you see patterns? Activities to Learn this Strategy
