Add and subtract fractions with unlike denominators and justify your solutions using manipulatives and mathematical reasoning.

__Lesson__

Too add or subtract fractions with unlike denominators, you must first find the least common denominator [or LCD] for the fractions. Next, you must find the equivalent fractions by multiplying the numerator as many time as you multiplied the denominator to get the LCD. After you have completed that, just find the sum or difference of the two numerators, and there's your answer.

__Example__

2/4 + 5/12 LCM=12 4*3=12 2*3=6 12*1=1 5*1=5

6/12 + 5/12 = 11/12

Use strategies to develop formulas for finding the circumfrence of circles.

In class, we figured out some of the strategies to develop formulas for finding the circumfrence of circles. We found out how to find the circumfrence of a circle with only knowing the diameter, and we learned that the circumfrence, divided by the diameter, equals pi, or 3.14. We also solved a little bit of problems for finding the circumfrence.

**Example Problem**

__Lesson__

The circumfrence divided by the diameter has the qoutient of pi, or 3.14. Also to find the circumfrence of a cirlce, you need to multiply the diameter by pi.
