1. Look at the picture in Part 1. How many groups of balloons are there?

   Show Answer Hide Answer

   3 groups of balloons.

2. How many balloons are in each group?

   Show Answer Hide Answer

   4 balloons.

3. How can we complete the multiplication statement?

   Show Answer Hide Answer

   3 groups \times 4 in each group = 12 total

4. Look at Part 2. Which expressions are equivalent? How do you know?

   Show Answer Hide Answer

   6\times 8 = 8\times 6 (commutative property);
   4\times (5\times 2) = (4\times 5)\times 2 (associative property);
   (2\times 3)\times 4=2\times3\times 4​(associative property);
   9\times 10=9\times 10\times 1
   (identity property).

5. Now, look at the model in Part 3. What fraction does each part of the rectangle represent? How do you know?

   Show Answer Hide Answer

   Each part is \frac 18, since there are 8 equal parts in the whole.

6. How many eighths are shaded?

   Show Answer Hide Answer

   6 eighths.

7. How can we write \frac 68 as a collection of unit fractions? How many unit fraction "groups" are there?

   Show Answer Hide Answer

   There are 6 groups of \frac 18: 

   \frac 68=\frac 18+\frac 18+\frac18+\frac18+

   \frac 18+\frac18.

8. How else can we write \frac 68 as the sum of fractions that have the same numerator and denominator as each other?

   Show Answer Hide Answer

   \frac 68=\frac 28+\frac 28+\frac 28, or \frac 68=\frac 38+\frac 38.
