We will also learn how to solve and evaluate Fractions and Proportions in word problems.. Lesson plan goals. We are constantly using fractions everyday. Most of the time not really even noticing that we are using fractions. Have you ever checked the clock or a watch for the time? Guess what the time is a fraction of a day so any time you use a watch, clock. .

He showed that the human body is built with each part in a definite golden proportion to all the other parts.. Remember to Silence Your Cell . Phone and Put It In Your Bag!. Proportional Variance.
