Students use estimation skills to run a business using Hot Dog Stand or Survival Math software. Students apply estimation skills to algebraic situation as they try to guess the equations to hit the most globs in Green Globs software. Determine the reasonableness of an answer by estimating the result of operations. Students estimate whether or not they can buy a set of items with a given amount of money. Calculate the exact price including tax.
Students evaluate various statements made by public figures to decide whether they are reasonable.
Students simulate estimating the number of fish in a lake by estimating the number of fish crackers in a box using the following method. Another sample is drawn and the number of tagged fish and the total number of fish are recorded. The estimate is further improved by taking additional samples, making predictions based on each sample of the total number of fish in the box, and finally averaging all the predictions. Develop, apply, and explain a variety of different estimation strategies in problem situations involving quantities and measurement. Students regularly have opportunities to estimate answers to straight-forward computation problems and to discuss the strategies they use in making the estimations.
