Today's class we worked on number of the day, 1269.584

Then Ordering Fractions Strategies.

1. Using landmarks, landmarks are things everybody should know.

eg. Let's meet at polo park.

I live near the forks.

bold words are landmarks

Fraction landmarks include:
1/10, 1/5, 1/4, 1/3, 1/2, 2/3, 3/4, 1/1

Practice: which is larger 11/15 or 7/10

Using our second strategy finding common denominators we see that 11/15 equals 22/30 and 7/10 equals 21/30. There for 11/15 is greater.

Third startegy is converting to decimals. Decimals are always over or out of one. So we follow the same steps as equivalent fractions only this time our equivalent fraction must be over 1.

For example: 3/5 converts to 0.6/1. We must divide 5 by 5 to have a denominator of 1. Therefor we must also divide the numerator by 5. So we get 3 divided by 5 equals 0.6

Things to remember a fraction is a part of a whole.

The line seperating the numerator and denominator means divided by.

I choose Jazzy as the next sribepost!
