1.4 Tutor Time! WARM UP January 7, 2016 Circulate and see what kids have for this. Make sure that they are able to create some sort of ratio. There is no need to go over this as a class since they will be doing a similar one in the beginning of today’s lesson. Just use it as a quick formative assessment. Address student misconceptions in Problem 1, #1.

1.4 Tutor Time! Lesson Opener as a class. Read the Lesson Opener as a class.

1.4 Tutor Time! Do #1a with your group. (pg 32) You have 1 min. Problem 1: Using Tables to Scale Up and Down Do #1a with your group. (pg 32) You have 1 min. Boxes of cookies rate members Have 4 students come up to draw on whiteboard. Do this as whole class. 400 Boxes 16 members

1.4 Tutor Time! Do #1b – f with your group.(pg 32) You have 4 min. Problem 1: Using Tables to Scale Up and Down Do #1b – f with your group.(pg 32) You have 4 min. Have 4 students come up to draw on whiteboard. Do this as whole class. 200 800 600 500

1.4 Tutor Time! Problem 1: Using Tables to Scale Up and Down From our solution to 1a we have a rate of 400 boxes 16 members 400 boxes 16 members = 25 boxes Have 4 students come up to draw on whiteboard. Do this as whole class. 1 member The unit rate is 25 boxes of cookies per Girl Scout.

1.4 Tutor Time! Problem 1: Using Tables to Scale Up and Down Each Girl Scout sells 25 boxes, so 50 Girl Scouts would sell 1250 boxes in a week. Have 4 students come up to draw on whiteboard. Do this as whole class. Each Girl Scout can sell 25 boxes, so it would take 23 to sell 575 boxes. 575 ÷ 25 = 23

1.4 Tutor Time! Do #2a-b with your group.(pg 33) You have 4 min. Problem 1: Using Tables to Scale Up and Down Do #2a-b with your group.(pg 33) You have 4 min. Have 4 students come up to draw on whiteboard. Do this as whole class.

1.4 Tutor Time! Problem 1: Using Tables to Scale Up and Down a. Write the relationship in this situation as a ratio or rate. The relationship is a ratio of 13 left−handed people 100 people because the units are both people. Have 4 students come up to draw on whiteboard. Do this as whole class. Is there a unit rate in this situation? b. 130 ≈ 3

1.4 Tutor Time! Do #3a-c with your group.(pg 33) You have 3 min. Problem 1: Using Tables to Scale Up and Down Do #3a-c with your group.(pg 33) You have 3 min. Have 4 students come up to draw on whiteboard. Do this as whole class.
