We discussed how to multiply mixed fractions and then played spin fractions. Spin fractions was an unfair game where one partner had to add the fractions and the other partner had to multiply the same fractions. The person that had the largest fraction got a point. Mrs. Arcuri gave unfair rules. The adder always won the point because adding fractions will always give you a larger fraction, compared with multiplying the. This is the opposite to whole numbers!!! Why is adding fractions always larger than multiplying? Multiplying Fractions a) convert fraction to an improper fraction if you can (with mixed fractions you can) b) multiply numerators c) multiply denominators and simplify View the Khan Academy video that helps explain how to multiply mixed fractions. We continued our discussion on "cross cancelling" when multiplying fractions. Students finished the back side of the Multiplying Fraction notes from yesterday. Click here for the Multiplying Fraction notes. View the Khan Academy video on multiplying fractions if you need a review or missed class. Today we looked at patterns between adding and multiplying. We also drew diagrams (fraction pies or chocolate bars) to help explain why 10 x 2/3 = 20/3 or 6 2/3 and why 1/2 x 1/2 = 1/4.

We will continue our conversation on cross cancelling tomorrow. Today was the grand opening of our new gym, which was a spirit assembly. Wow, look at the new paint job!
Note: Term 2 has now started. Students did some on-line practice with adding/subtracting fractions, click on Khan Academy. Also see the Math 8 page for some on-line fraction games.
