Today’s Goal Is To:
•Explore importance of vocabulary and writing in the learning of mathematics
•Provide vocabulary and writing strategies
•Share and discuss students’ work samples
•Allow for collaboration among teachers
Vocabulary and Writing, Why are They Important?
• Mathematics language
•Word knowledge, oral expression
•Clarify thinking
“Student mastery of a word means they can decode,
pronounce, spell, define it, write a meaningful sentence with it, and recognize it in a
different contest.” (Calderon, 2007)
NCSCS: Collect, organize, analyze, and display data (including scatterplots) to solve problems
The scatterplot above shows the number of people at the swimming pool from 1:00 – 5:30. What conclusion can be made about the number of people at the pool during this time span? How can a manager use this information to staff the pool?
1. What would a correct response contain?
1. What vocabulary would prevent your students from being able to answer successfully?
Compare the students’ responses that follow.
1.Which response is the most acceptable? Why?
1.What role does vocabulary play in the clarity of each response?
1.Which words appear to be the issue?
Student 1
Teacher: In reading this question, it says the scatterplot above shows the number of people in the swimming pool from 1:00 -5:30. What conclusion can be made about the number of people at the pool during this time span?
Student 1: Uh. That it decreased as time passed. As it got later a lot of people started to leave.
Teacher: Ok. How can a manager use this information to staff the pool?
Student: I think that they shouldn’t need that many staff, much staff because there is not that many people there. So they could use to use fewer people, fewer staff.
Teacher: Ok. Now looking at this graph, how many people were at the pool at 2:30?
Student: About 14 people.
Teacher: Ok. At what time were there about 9 people at the pool?
Student: Uh, about 30, 35.
Teacher: Ok. What does the data pair (5:30, 5) represent?
Student: Uh. 5:30 is the hour and 5 is the number of people that were there.
Teacher: Do you see anything else, you want to say about the graph?
Student: That it’s a line graph.
Teacher: Thank you, very much.
Student 2
Teacher: In reading this question, it says the scatterplot above shows the number of people in the swimming pool from 1:00 -5:30. What conculsion can be made about the number of people at the pool during this time span?
Student: Uh. More people go at 1 o’clock and at 6:30 more people go. It lowers down at 3:00. It’s going down.
Teacher: Anything else?
Student: No.
Teacher: How can the manager use this information to staff the pool?
Student: He needs like to open early because there’s a lots of people go early. And, uh, he needs to know what time he needs to close to and when people need to leave. And that there is more people coming at 1:00.
Teacher: How many people were at the pool at 2:30?
Student: About 14.
Teacher: At what time was there about nine people at the pool?
Student: At 4.
Teacher: Ok. What does the data pair (5:30, 5) present?
Student: Uh. The number of people at the pool.
Teacher: Ok. Anything else?
Student: No.
Student 3
Teacher: I’m going to ask you a few questions about this graph. , it says the scatterplot above shows the number of people in the swimming pool from 1:00 -5:30. What conclusion can be made about the number of people at the pool during this time span?
Student: Doing, the time span? Ummm. (wait) well it’s like at 1 to 5:30 people come to the pool. Then it was at well it’s at more people at the pool at 1:30. Then when it comes 5:30 people are leaving the pool or something. That’s what I think it might mean.
Teacher: Ok. How can a manager use this information to staff the pool?
Student: So he will know how many people are there. How many people to monitor. And how many people he has to watch over.
Teacher: Ok. How many people were at the pool at 2:30?
Student: Ummm. About 14.
Teacher: At what time was there about 9 people at the pool?
Student: Um. At, I would say about 4, or 4.5
Teacher: What does the data pair (5:30, 5) represent?
Student: How many people were at the pool at 5:30.
Teacher: Alright, thank you.

Key Vocabulary Issues for ELLs
•Same Words Different Meaning
•Similar Meanings Different Precision
•Complete understanding
Why is vocabulary so challenging in mathematics?
•Signal Words (transitions and connectors)
•Cognates
•Symbols
•Homophones
•Polysemous
Teach words that are needed to:
•Understand a text
•Use in writing
•Answer a test question
•Enhance academic verbal repertoire
Signal Words
Topic Words
Addition Sum, Increased by, More than
Subtraction Decreased by, Subtract, Take away
Multiplication Product, Doubled, Times as much

Vocabulary Indicators1. Teacher says word and student repeats 3 times
2. Provide word in context from the text
3. Provides dictionary or technical definition
4. Provide definition in student friendly terms
5. Prove example(s) of word use, including multiple meanings when necessary
6. Point out helpful structures: prefix, suffix, cognate, tense, compound word, spelling, polysemy, pronunciation
7. Engage 100% of the students in the production of the word

Why write?
“Exposure to the written word and basic reading skills helps
students develop a larger vocabulary.” (Calderon, 2007)
Advantages for Students
• Helps student raise questions about new ideas
• Allows chance for reflection on what is known
• Allow students to construct mathematics for themselves
• Helps student keep thoughts organized
• Helps address issue of “math anxiety”
Writing Types to Use in Mathematics
• Journals
• Freewriting
• Learning Logs
• Note to Teacher
• Mathographies
• Formal Writing
• Expository
As teachers of mathematics, we sometimes forget that the words and phrases that are familiar to us are foreign to our students. Students need to master this language if they are to read, understand, and discuss mathematical ideas.
- Thompson & Rubenstein
Student 1
1. What does the data pair (5:30, 5) represent?
Student response: That less people swim at later times of the day.
Student 2
Student response: 1 I can conclude that more people swim in earlier times of the day, and that less people swim in later times of the day. 2 She could use this information so that she can know how many staff to hire for certain jobs.
1What conclusion can be made about the number of people at the pool from 1:00-5:30? 2How can a manager use this information to staff the pool?
