Approximately How Difficult?

Being able to figure the distance from point A to point B is a task many people take for granted (or in some cases, can’t do very accurately). Everyday, people estimate how much their grocery bill is going to be at the supermarket or how long it will take to complete a list of errands. Getting your students to work on such skills now, means they will get better and better at it as time goes on. Have each student turn in his or her estimate, then at the end of the day assign a few students to determine the exact answer to the problem. Award those with the most accurate answer with a treat, or give titles for “Top Estimator of the Week” by putting their name on the chalkboard. The list of exercises below will get you started.
