Clarifying Activity Students discuss the different strategies for computational estimation involving rounding. Each student selects a strategy that he or she prefers to use and finds another student who prefers a different strategy. The two students compare their results as they do whole number and decimal calculations. The student estimates to determine reasonable results. Clarifying Activity Students use a Texas road map to create problems involving mileage and population that must be solved using estimation.
Students trade and estimate solutions to one another's problems.
