Monica wants to make chocolate milk for her family. Monica likes it just as much chocolate as milk. Her brother likes it REALLY chocolatey. Her mother wants only milk. Her dad likes just a little chocolate. Help Monica determine the mix for each member of her family.
What ratio of chocolate is needed to make 1 C. of chocolate milk? What ratio of milk is needed to make 1 C. of chocolate milk?What is the total ratio of chocolate and milk?MonicaBrotherMomDadSlide2

These are called:
scaling ratiosSlide5
In table groups work on p. 6 - 7Part-to-whole Ratio 1 : 4 Scale up 12 : 48 48 oz. pitcher
Double check: 1 can concentrate = 12 oz.
3 cans water = 36 oz. Total = 48 oz.A. A typical can of o.j. concentrate holds 12 fluid oz. The standard recipe is:How large of a pitcher will you need to hold the juice made from a typical can? (Show or explain your answer)Slide6
A typical can of lemonade concentrate holds 12 fluid oz. The standard recipe is:How large of a pitcher will you need to hold the lemonade made from a typical can? (Show or explain your answer)Part-to-whole Ratio 1 : 5 ⅓ Scale up 12 : 64 oz. 64 oz. pitcher
Double check: 1 can concentrate = 12 oz. 4
⅓ cans water = 52oz. Total = 64 oz.Slide7
Part-to-whole Ratio 1 : 5 ⅓ Scale up 12
: 64 oz.Slide8
1 Gallon = 128 oz. 1 : 3 (part to part) 1 : 4 (part to whole) x : 128 (scale factor of 32)32 : 128She needs 2 (16 oz.) cans!
1 : 4 (Part-to-whole) Scale up 16 : 64 64 oz. container Slide9
15 oz. of lemonade concentrate 1 : 4 ⅓ (part to part)1 : 5⅓ (part to whole) scale factor of 1515 oz : 80 ozHe needs a pitcher large enough to hold 80 oz.Slide10
