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.
