8. Entry : Today’s Objective
I will multiply fractions, decimals, and percents and assess the reasonableness of answers. 
HOW WILL I BE ASSESSED?
Quiz Friday with at least one of the problems from today on it EXACTLY AS IS
HW tonight with 5 problems, at least 1 of which will also be on Friday’s quiz
Chapter test where I will have to draw a model of multiplying fractions

9. Entry # Multiplying Mixed Numbers
An efficient method for multiplying mixed numbers is to convert them to fractions greater than one, find the product as you would with fractions less than one, and then convert them back to a mixed number, if necessary.

11. DURING TEAM WORK…
I work cooperatively with my team members to accomplish a particular goal by:
Performing assigned tasks/roles
Listening to my team members
Respecting the ideas of others
Being a helpful contributor to the team.

12. 5-39.  At the beginning of class, Lorna turned to her team and said, “Wow!  We have to go shopping at Daisy’s tomorrow!  Sunglasses are on sale for 70% off, and I have a coupon for 40% off!  That makes 110% off, so the store will have to pay me!  How cool is that?”  “No way!”  Mandy said.  “If sunglasses are 70% off, that means you only have to pay 30% of the original price, right?  If you have a 40%-off coupon, then you pay 60% of the price.  30% and 60% is 90%, so you would actually have to pay 90% of the regular price.  Oops, this means that the coupon makes you pay more!  That doesn’t make sense!” Tony suggested that they use what they know about finding parts of parts to figure out what the sunglasses will actually cost.

14. 5-40
As you answer the questions below, think about multiple representations of portions to help you make sense of multiplying percents and decimals. Tony thought about the sunglasses sale in problem 5-39 in a different way.  He realized that if you took advantage of the sale, then using the coupon meant you would pay 60% of 30%.  If you have not done so already, represent 60% of 30% using decimals.  Write the result of calculating 60% of 30% as a decimal.  Explain Tony’s method.   
To find 40% of 20%, Chika used decimal multiplication.  She thinks that 0.4(0.2) = 0.8.  Is she correct?  Work with your team to find a way to show whether Chika’s answer makes sense.   
What happens when you multiply one tenth by one tenth?  Use fraction multiplication to find the answer, and then represent the problem and answer using decimals. 
Multiply .  Then represent this problem and answer using decimals.
Calculate the correct answer to Chika’s product from part (b).
In parts (a) through (e), you multiplied parts by parts.  Compare the products to the numbers that were multiplied.  Which products are greater than or less than the numbers multiplied? 

15. 5-41
Ben and Connor needed to calculate 20% of   They started by drawing the generic rectangle at right. Why did they write ?
Copy their generic rectangle on your own paper and work with your team to label the missing dimensions and areas with fractions.  Find the product and then express it as a decimal.

17. DURING OPEN DISCUSSION…
I contribute my ideas to class discussion.
I listen to others when they are speaking.
I wait for the appropriate time to contribute my ideas.
I am polite in my interactions with other students and the teacher.

18. 5-43
5-43. Mohammed is multiplying 3.9(0.6).  His work is shown below. Is it correct?

20. WHEN I STAND AND DELIVER…
I go quickly to the white board when it is my turn.
I print my name on the white board neatly and complete the assigned task on the white board.
I complete the problem as a notebook entry if it is not my turn to be at the board.
I stand at attention to show my teacher when I am done and requesting permission to be seated.
I address the teacher as “sir” or “ma’am”.
I ask or answer a question in a clear, loud voice.

21. Entry : Board Work I will call out problems out loud
One person from each group at a time goes to the board, prints their name on the board, listens to the problem and copies it down and solves it
Everyone else copies the problem onto their notebook as an entry
