1 EXERCISING
Our Goals:
Calculate percentages of a total
Given a percentage of a total, calculate the
corresponding value
Discuss in your group
Do you exercise? How often? Which
activities do you do?
If I ate a brownie (132 calories) and I want
to burn 75% of its calories, how many
calories should I burn?
Loren wants to be healthy and decides to
work out. During an 50 minute interval, she
runs for 41 minutes. What percentage of
the time did she run?

2 SUGARY DRINKS

2 SUGARY DRINKS
Our Goals:
Practice conversions using ratios, and compare different ratios
Use ratios and proportionality to generate new information
Discuss in your group
Which things you notice when you drink too much of a sugary drink?
If a drink has 10g of sugar in a 16 oz cup, how many grams of sugar
does it have in a 12 oz cup?
Which has a smaller concentration of sugar: a 12 oz cup with 18g of
sugar, or a 8 oz cup with 14g of sugar?

2 SUGARY DRINKS
According to the American Heart Association (AHA), the
maximum amount of added sugars you should eat in a
day are (7): Men: 150 calories per day (37.5 grams or 9
teaspoons). Women: 100 calories per day (25 grams or 6
teaspoons).
Sugar is bad for you a because it has calories, and
because if you have diabetes or a diabetes-related
condition — like high blood fat levels — then having sugar
will increase your blood sugar and your triglycerides, a
risk factor for heart disease. (Triglycerides are a type of
fat in the blood.)
When we look at the types of foods that are high in added
sugar, they often are not high in nutrition. So eating a lot of
sugar is a general indication that maybe you aren't eating
as healthy of a diet as you could.
Sugar does one of two things. It either displaces more
nutritious foods in your diet, which means you're screening
out nutritious-dense foods, or it adds calories to your diet.
So if you're adding calories on top of an already nutritious
diet that puts you at risk for weight gain.

3 A BALANCED DINNER
UCI Math CEO
• Meeting 4 (MAY 3

3 A BALANCED DINNER
Our Goals:
Set up expressions representing real-life quantities, using variables
Use sum and multiplication to compute quantities in a real-life context
Discuss in your group
Can you give examples of fat, protein and carbohidrates?
If A represents the number of grapes I ate and B represents how
many calories each grape has, what does A x B represent?
If A represents the total of pistachios in a Jar before we ate some,
B represents the total you ate, and C represents the total I ate, how
can we represent the number of pistachios that remain?

same amount. What percentage of the total did each kid bring?
Of the recommended 50g daily protein, I ate 15% of it in the morning
and 55% of it in the afternoon. How many grams should I eat at night
to get to achieve the Daily Take recommendation?
