Mathematics in Context: Models You Can Count on

Encycbrita, "Mathematics in Context: Models You Can Count on"

Dear Student,
Welcome to the unit Models You Can Count On.
Math students today can no longer be comfortable merely doing
pencil and paper computations. Advances in technology make it more
important for you to do more than perform accurate computations.
Today, it is important for you to make sense of number operations. You
need to be able solve problems with the use of a calculator, confident
that your result is accurate. When shopping in a store, you need to be
able to estimate on the spot to make sure you are getting the best
deal and that the cash register is working properly.
In this unit, you will look at different number models to help you
improve your understanding of how numbers work. You will examine
various recipes that could be used to feed large groups of people. You
will consider how students can share garden plots. You will observe
computer screens during a program installation. You will make sense
of signs along a highway or bike trail. In each situation, a special model
will help you make sense of the situation. You will learn to use these
models and count on them to solve any problem!
We hope you enjoy this unit.
Sincerely,
The Mathematics in Context Development Team
