Math Unit 5 Test: Data & Geometry
Directions for the grown-up
Give this test on a calm day, after the unit's last lesson. Sit with your child and read the directions for each part aloud. Read any item aloud if your child asks. Reading is not what this test checks. Do not time the test. The time given is only a guide, so you can plan. Take a short break between parts if your child is tired. Do not teach or hint during the test. If your child is stuck, say "Do your best, then we can move on." When you score, use the answer and the partial-credit notes for each part. Then add the points and find the level at the end. Your child may use the tools from the lessons: a ruler for drawing lines and shapes, grid paper or square crackers or sticky notes for rectangles, and crayons for shading and bar graphs. Straight lines drawn by hand are fine if they are close to equal.
Part 1: Graphs & Data (12 points)
Standards: 2.MD.D.9, 2.MD.D.10
- Rafi measured 10 pencils in inches: 5, 6, 6, 7, 5, 6, 8, 7, 6, 5. Make a line plot. Use a number line from 5 to 8. Add a title and the label Inches.Answer: 5: 3 Xs; 6: 4 Xs; 7: 2 Xs; 8: 1 X. Title and the label Inches are included. · 2 points
- Use your line plot. (a) Which length is most common? (b) How many pencils are 7 inches or longer?Answer: (a) 6 inches (b) 3 (2 + 1 = 3) · 2 points
- Favorite fruit votes: apples 6, bananas 9, grapes 4, pears 2. Make a bar graph. Add a title and label both sides.Answer: Bars of 6, 9, 4 and 2, with a title and both labels. · 2 points
- Use your bar graph. How many more children chose bananas than grapes?Answer: 5 (9 − 4 = 5) · 2 points
- How many children voted in all?Answer: 21 (6 + 9 + 4 + 2 = 21) · 2 points
- How many fewer children chose pears than apples?Answer: 4 (6 − 2 = 4) · 2 points
Scoring: Graph items (1 and 3): 1 point for correct Xs or bars and 1 point for the title and labels. Item 2: 1 point for each part. Items 4–6: 2 points for the right number; 1 point for a correct equation with a small counting slip.
Reteach: Week 25, Week 26Week 25 Days 2–4 (building and reading line plots) and Week 26 Days 2–4 (picture graphs, bar graphs and compare questions).
Part 2: Shape Attributes (8 points)
Standards: 2.G.A.1
- (a) What is the name of a shape with 6 sides? (b) How many vertices does it have?Answer: (a) hexagon (b) 6 · 2 points
- A quadrilateral has how many sides? How many vertices?Answer: 4 sides, 4 vertices · 2 points
- A cube has how many faces? What shape is each face?Answer: 6 faces; each face is a square · 2 points
- Tom says a long, skinny shape with 3 sides is not a triangle. Is Tom right? Why?Answer: No. It has 3 sides and 3 vertices, so it is a triangle. Size and shape stretch do not change the name. · 2 points
Scoring: 1 point for each part. Item 4: 1 point for "no" and 1 point for a reason about 3 sides or 3 vertices.
Reteach: Week 27Week 27 Days 1–4 (counting sides and vertices, drawing shapes, and cubes).
Part 3: Partitioning (12 points)
- Draw a rectangle. Split it into 3 rows and 4 columns of same-size squares. How many squares? Write an addition equation.Answer: 12 squares; 4 + 4 + 4 = 12 (or 3 + 3 + 3 + 3 = 12) · 3 points
- Draw a circle. Split it into fourths. Shade one share. What is one share called?Answer: Four equal parts, one shaded. One share is one fourth (or one quarter). · 3 points
- Draw two same-size rectangles. Split each one into halves a different way.Answer: Two rectangles, each split into two equal parts, with two different lines (for example, one up and down, one across or corner to corner). · 3 points
- A pizza is cut into 3 equal shares. (a) What is each share called? (b) How many thirds make the whole pizza? (c) Is one third bigger or smaller than one half of the same pizza?Answer: (a) one third (b) 3 (c) smaller · 3 points
Scoring: Item 1: 1 point for rows and columns of equal squares, 1 point for 12, 1 point for the equation. Item 2: 1 point for four equal parts, 1 point for shading one, 1 point for the name. Item 3: 1 point for each correct rectangle, 1 point for the two ways being different. Item 4: 1 point for each part. Shares should look close to equal; do not take points for small drawing wobbles.
Reteach: Week 28, Week 29Week 28 Days 1–3 (rows and columns of squares and repeated addition) and Week 29 Days 1–4 (halves, fourths and thirds).
Part 4: Extended Response (8 points)
- Mom has a square pan of cornbread. Four people will share it fairly. (a) Draw two squares. Split each one into fourths a different way. (b) Are the shares in your two squares the same size, even if they look different? Explain.Answer: 4 points: two squares, each split into 4 equal shares in different ways (for example, a 2-by-2 grid and 4 strips, or both diagonals), and an explanation that each share is one fourth of the same whole, so they are the same size. 3 points: both drawings right and a partial explanation. 2 points: one correct drawing and some explanation, or two correct drawings and no explanation. 1 point: one correct drawing only. 0: no equal fourths shown. · 4 points
- A family voted on a favorite pet: dog 8, cat 5, fish 3, bird 4. Make a picture graph or a bar graph with a title and labels. Then write one "how many more" question about your graph and answer it.Answer: 4 points: graph shows 8, 5, 3 and 4 correctly with a title and labels; a how-many-more question with a correct answer (for example, How many more chose dog than fish? 8 − 3 = 5). 3 points: correct graph and question with a small slip, or missing title or labels. 2 points: correct graph with no question, or a question and answer with graph errors. 1 point: some correct bars or pictures. 0: no graph. · 4 points
Scoring: Use the rubric in each answer.
Reteach: Week 26, Week 29, Week 30Week 29 Days 1–4 (equal shares and fair sharing), Week 26 Days 3–4 (bar graphs and compare problems) and Week 30 Day 4 (data and equal shares in one task).
