Sommaire

This 1st grade graphing data test answer key covers organizing and reading data (Common Core 1.MD.C.4), with a free PDF to print.

Key takeaway: This answer key helps Grade 1 teachers score the data test and learn where students need more help.

Topic: Organizing and Reading Data (1st grade)
Content: Worked solutions and a scoring guide for 8 questions
Standards: 1.MD.C.4
Answers: Every step shown, with the method to review
Format: Free printable PDF, US Letter, black and white

This answer key helps Grade 1 teachers score the data test and learn where students need more help. It gives the correct answer for every part and shows how points are earned on each of the 8 questions.

Tally counts, graph reading, and comparing have one correct answer each. Question 2 and question 6 involve drawing, so the key describes what a correct drawing includes. Scoring takes about ten minutes for a small class, and the notes point to the skill behind each question.

Use this answer key to score the test out of 20 points. Each answer shows the number sentence and a scoring guide. Give part points when the work is right but the answer has a small counting slip.

1st grade graphing data test answer key: worked solutions

1 – Weather tally [2 pts]

8 sunny days.
3 rainy days.

Scoring: 1 point for each correct count.

2 – Draw tally marks [2 pts]

Twelve is two groups of five and 2 more lines.

\(5 + 5 + 2 = 12\). So, there are 2 groups of five.

Scoring: 1 point for a drawing with 12 lines. 1 point for 2 groups of five.

3 – Recess toys [3 pts]

Chalk (7 is the biggest number).
\(7 – 4 = 3\). 3 more
\(6 + 4 = 10\), then \(10 + 7 = 17\). 17 children

Scoring: 1 point for each part.

4 – Pizza toppings [3 pts]

7 children.
\(5 – 3 = 2\). 2 fewer
\(5 + 3 = 8\). 8 children

Scoring: 1 point for each part.

5 – Crayon box [2 pts]

\(5 + 7 = 12\). Then \(18 – 12 = 6\).

6 green crayons

Scoring: 1 point for a correct number sentence. 1 point for the answer 6.

6 – Vehicle graph [3 pts]

A correct picture graph.

\(6 – 4 = 2\). 2 more cars

Scoring: 2 points for 4, 6 and 3 circles in the right rows (1 point if only two rows are right). 1 point for the answer 2.

7 – Library books [3 pts]

True: \(9 – 4 = 5\).
False: 6 is more than 4.
False: \(9 + 4 + 6 = 19\).

Scoring: 1 point for each correct answer.

Question 8 and after

8 – Playground votes [2 pts]

\(5 + 4 = 9\), then \(11 – 9 = 2\). 2 children chose the seesaw.

Swings have 5, slide 4, seesaw 2. Swings got the most.

Scoring: 1 point for 2. 1 point for swings.

Key facts behind this 1st grade graphing data test answer key

Key facts

Data is information we collect, such as votes.
Next, a tally mark is one line for one vote, and every fifth line crosses four lines.
In a picture graph, each picture stands for one vote.
Then, in a bar graph, a taller bar means more votes.
Add to find the total. Take away to find how many more or how many fewer.

Common mistakes with this 1st grade graphing data test answer key

Marking a drawing correct only by the total number of marks misses the grouping. Also, check that question 2 uses groups of five with a slash.
In question 6, the counts 4, 6, and 3 must match the bars or pictures. Do not give full credit for a graph with the right title but wrong counts.
Also, on question 7, a true or false item with no matching evidence may be a guess. Then, look at the child’s work for the numbers they compared.

How to learn from your test

Sort missed questions into reading tally marks, reading graphs, drawing graphs, and comparing. Reteach the skill most students missed.
Next, return the test and ask each child to correct one problem by counting again. Recounting is the best fix for most graph errors.
Parents should look at the type of error. A child who counts well but adds instead of subtracting needs help with the words how many more.

1st grade graphing data test answer key: frequently asked questions

How should a graph the student drew be scored?

Give credit for each correct part: a title or labels, the right count for each category, and neat equal-sized pictures or bars. A graph with all counts correct but a missing title can earn most of the points. Next, keep the same rule for every student.

What if a student gives the right number but leaves out the label?

In Grade 1, a number is usually enough unless the question asks for a word or unit. If the question asks which toy, the name is needed. Also, check the question carefully, and use the same rule for the whole class.

What should I teach after students finish a data test?

Start with the skills most students missed. If drawing graphs was weak, collect real data in class and graph it together. If comparing was weak, practice how many more with objects. Then connect the work to word problems, since graphs often supply the numbers for them.
