13. PROBLEM OF THE DAY Sarah makes soup. She divides each batch equally into thirds to give away. Each family that she makes soup for gets 1 third of a batch. Sarah needs to make enough soup for 5 families. How much soup does Sarah give away? Write your answer in terms of batches. Extension: What fraction will be left over for Sarah?

14. CONCEPT DEVELOPMENT TAKE OUT YOUR FRACTION STRIPS ARRANGE THE FRACTION STRIPS IN ORDER FROM THE LARGEST TO THE SMALLEST UNIT THUMBS UP WHEN YOU’RE DONE

16. What happens when we aren’t using fraction strips? What if we’re talking about something round, like a pizza? Is 1 half still larger than 1 third? Turn and talk to your partner about why or why not. Sharing a pizza between 3 people is not as good as sharing it between 2 people. I think pieces that are halves are still larger. I agree because the number of parts doesn’t change even if the shape of the whole changes

17. Draw 5 circles that are the same size to represent pizzas on your white board or in your notebook. Estimate to partition the first circle into halves. Label the unit fraction. THUMBS UP WHEN YOU’RE DONE 1/2 Estimate to partition the second circle into thirds. Label the unit fraction. THUMBS UP WHEN YOU’RE DONE 1/3 The more we cut, what’s happening to our pieces? They’re getting smaller! So is 1/3 smaller than ½? Yes! Partition the remaining circles into fourths, sixths, and eighths. Label the unit fractions. THUMBS UP WHEN YOU’RE DONE 1/4 1/6 1/8 Compare your drawings to your fraction strips. Talk to a partner: Do you notice the same pattern as with your fraction strips? Discuss at your table.

18. Comparing Fractions WORK WITH SOMEONE AT YOUR TABLE. Let’s compare unit fractions. For each turn, you and your partner will each choose any single fraction strip. Then decided if whose fraction is : Greater than or if your fractions are equal. THUMBS UP IF YOU UNDERSTAND.

19. THINK IN YOUR MIND WHICH FRACTION STRIP YOU’RE GOING TO CHOOSE. WHEN I PUT MY HANDS IN THE AIR. GRAB YOUR FRACTION STRIP. EACH ROUND I WILL RANDOMLY SELECT IF THE LARGER FRACTION STRIP WINS OR THE SMALLER FRACTION STRIPS WINS.
