Scoring: Items 1–4: 2 points for the right answer; 1 point if the answer is off by 5 minutes or less because of one counting slip. Item 5: 1 point for 5:35, 1 point for jumps or steps shown and 1 point for a clear explanation.

Reteach if needed: Week 25. Week 25 Day 1 (time to the minute), Week 25 Days 2–3 (elapsed time within the hour and across the hour) and Week 25 Day 4 (start time, end time and elapsed time word problems).

Which holds about 1 liter: a spoon, a large water bottle or a bathtub? Explain your choice.
(2 pts)
Answer: A large water bottle. Look for: a spoon holds much less than 1 liter and a bathtub holds much more.

Scoring: Item 1: 2 points if all four are right; 1 point if two or three are right. Items 2–4: 2 points for the number and unit; 1 point for the number without a unit. Item 5: 1 point for the water bottle and 1 point for a sensible reason.

Reteach if needed: Week 26. Week 26 Days 1–2 (grams and kilograms), Week 26 Day 3 (liters) and Week 26 Day 4 (one-step mass and liquid volume word problems).

Part 3: Area

15 points

Find the area. Write square units in each answer.

11.
A rectangle on grid paper has 5 rows with 6 squares in each row. What is its area?
(2 pts)
Answer: 30 square units
12.
A card is 7 centimeters long and 4 centimeters wide. What is its area?
(2 pts)
Answer: 28 square centimeters
13.
Which unit would you use for the area of a classroom floor: square centimeters or square meters?
(2 pts)
Answer: Square meters
14.
Find the area of a 9 by 7 rectangle by splitting it into a 5 by 7 rectangle and a 4 by 7 rectangle. Show both parts.
(2 pts)
Answer: 5 × 7 = 35 and 4 × 7 = 28; 35 + 28 = 63 square units
15.
An L-shape is made of a 6 by 4 rectangle and a 3 by 2 rectangle that do not overlap. What is the area of the L-shape?
(2 pts)
Answer: 30 square units (24 + 6)
16.
A rectangle has an area of 54 square feet. One side is 9 feet long. How long is the other side?
(2 pts)
Answer: 6 feet
17.
Rosa covers a rectangle with 1-inch square tiles. There are 3 rows with 8 tiles in each row. (a) What is the area? (b) Explain why multiplying the side lengths gives the same answer as counting the tiles.
(3 pts)
Answer: (a) 24 square inches (b) Look for: the tiles make 3 equal rows of 8, so 3 × 8 counts every tile.

Scoring: Items 1, 2 and 6: 2 points for the number with the right unit; 1 point for the right number with a missing or wrong unit (for example, centimeters instead of square centimeters; the answer to item 6 is a length, so it is in feet). Item 3: 2 points. Items 4–5: 1 point for the parts and 1 point for the total. Item 7: 1 point for 24 square inches and up to 2 points for the rows explanation.

Reteach if needed: Week 28, Week 29. Week 28 Days 1–3 (area with unit squares and counting by rows), Week 28 Day 4 and Week 29 Day 4 (L-shapes), Week 29 Days 1–2 (multiplying side lengths; unknown side) and Week 29 Day 3 (splitting a rectangle).

Part 4: Perimeter

11 points

Find the perimeter or the missing side. Write the unit.

18.
What is the perimeter of a rectangle that is 8 units long and 3 units wide?
(2 pts)
Answer: 22 units
19.
A shape with 5 sides has side lengths of 5, 8, 6, 4 and 9 centimeters. What is its perimeter?
(2 pts)
Answer: 32 centimeters
20.
A square has a perimeter of 28 inches. How long is each side?
(2 pts)
Answer: 7 inches
21.
A rectangle has a perimeter of 32 feet. Its length is 9 feet. What is its width? Show how you found it.
(2 pts)
Answer: 7 feet (9 + 9 = 18; 32 − 18 = 14; 14 ÷ 2 = 7)
22.
Ty says a rectangle that is 2 units by 5 units has a perimeter of 10 units because 2 × 5 = 10. Is Ty right? Explain and find the perimeter.
(3 pts)
Answer: No. The perimeter is 14 units (2 + 5 + 2 + 5). Look for: perimeter is the distance around, so you add all four sides; 10 is the area in square units.

Scoring: Items 1–3: 2 points for the number and unit; 1 point for the number only. Item 4: 1 point for subtracting the two lengths and 1 point for 7 feet. Item 5: 1 point for "no," 1 point for 14 units and 1 point for explaining that perimeter adds the sides (10 is the area).

Reteach if needed: Week 30. Week 30 Days 1–3 (perimeter by counting unit lengths and adding sides) and Week 30 Day 4 (finding an unknown side from the perimeter).
