Time, Area, and Data

1. Start at 3:25 p.m.

Break 35 minutes into 30 minutes and 5 minutes.

First add 30 minutes:

$3:25 p.m. + 30 minutes = 3:55 p.m.$

Then add 5 more minutes:

$3:55 p.m. + 5 minutes = 4:00 p.m.$

Maya finishes reading at 4:00 p.m.

2. Relay race:

$9:10 to 9:35 = 25 minutes$

Long jump:

$9:45 to 10:00 = 15 minutes$

$10:00 to 10:20 = 20 minutes$

$15 + 20 = 35 minutes$

Snack break:

$10:20 to 10:35 = 15 minutes$

The events are 25 minutes, 35 minutes, and 15 minutes long. The long jump is the longest event.

3. The rectangle has 7 rows of 4 square units, or 4 rows of 7 square units.

Use multiplication:

$7 \times 4 = 28$

The area is 28 square units. Multiplication helps because the same number of unit squares appears in each row.

4. Find the area of each rectangle.

Rectangle A:

$5 \times 4 = 20$

Rectangle B:

$3 \times 4 = 12$

Add the areas because the rectangles do not overlap:

$20 + 12 = 32$

The total area of the rug is 32 square feet.

5. Add all the books:

$6 + 4 + 8 + 5 = 23$

The students read 23 books altogether.

Compare Carla and Ben:

$8 - 4 = 4$

Carla read 4 more books than Ben.
