Definition of an Estimate: A
guess of the actual value or number of something with some thought
or mathematical calculation involved. Example: I guess there are 80
gumballs shown in the picture at the top of this page. I based that
on multiplying 10 (column) times 8 (row). You can count them, if you
wish, and see how close I came to this estimate.

Lesson Idea for Teachers:
Estimating with Dinosaurs: Provide a set of 8 different
pictures of dinosaurs, and place one set on each student's desk.
Individually the students will examine the picture and estimate the
size they think the dinosaur are if they were real. Each student
will write down his or her answer. Afterwards students will check an
Encyclopedia to find the actual measurements of the dinosaurs. Lesson
