Mathematical Vocabulary

Overview

This is Lesson 1 of 10 in the unit "Math Meets Language Arts" designed for Grade 6 students. In this introductory lesson, students will explore essential mathematical vocabulary, understand how precise language shapes mathematical understanding, and collaboratively create a Math Vocabulary Word Wall. The lesson ties English Language Arts skills directly with math concepts as per the Alberta Program of Studies for Grade 6 ELA and Mathematics.

Connections to Alberta Curriculum

English Language Arts (ELA) – Grade 6

General Outcome:

• 1. Students will listen, speak, read, write, view and represent to explore thoughts, ideas, feelings and experiences.

Specific Learning Outcomes (SLOs):

• 1.1 Listen to understand and respond appropriately in conversations and group discussions.
• 2.2 Read for meaning using strategies and cues to construct, monitor, and confirm meaning.
• 3.3 Use a variety of strategies to spell familiar and unfamiliar words correctly.
• 4.1 Express ideas and information in writing and other media, in a variety of forms and for a variety of purposes.

Mathematics – Grade 6

General Outcome:

• Students will create and communicate their mathematical understanding in a variety of ways.

Specific Outcomes:

• 3.1 Communicate mathematical ideas in many ways, using concrete, pictorial, and symbolic representation.
• 3.2 Use mathematical vocabulary to explain and justify solutions.

Learning Objectives

By the end of this 60-minute lesson, students will be able to:

• I can identify and explain the meaning of ten key mathematical vocabulary terms.
• I can use mathematical vocabulary words correctly in conversation and writing.
• I can collaboratively create a classroom Math Vocabulary Word Wall to support ongoing learning.

---

Success Criteria

Students will demonstrate success when they:

• Accurately match mathematical terms with their definitions.
• Use mathematical vocabulary in oral discussions and in written sentences.
• Contribute at least one word (term + student-friendly definition) to the Word Wall.
• Demonstrate understanding by explaining terms to peers.

• Markers and pens
• Printed vocabulary lists (10 key terms) with definitions (dyslexia-friendly font: OpenDyslexic)
• Mini whiteboards or notebooks for quick writing
• Visual aids: images/diagrams representing key terms
• Timer for activities

Lesson Timeline

1. Introduction (10 minutes)

• Engage: Begin with a short class discussion: "How is language important when we talk about math?"
• Prompt students: “What happens if we do not use the right words in math?” Discuss briefly to activate prior knowledge.
• Introduce the lesson objective using “I can…” statements on the board.

2. Vocabulary Exploration (15 minutes)

• Divide the class into small groups of 5.
• Provide each group with 10 index cards: 5 with vocabulary terms, 5 with definitions mixed up.
• Task: Match the word with the definition collaboratively, using dyslexia-friendly printed cards.
• Circulate and support groups, asking probing questions to deepen understanding.

3. Making Connections (10 minutes)

• Each group picks 2 words to write an original sentence or draw a simple visual representation on mini whiteboards/notebooks.
• Invite students to share sentences or visuals aloud with the class, reinforcing proper usage.

4. Create the Word Wall (15 minutes)

• Each student writes one chosen word and a short, student-friendly definition in their own words on a colourful sticky note or index card.
• Post these on the Math Vocabulary Word Wall.
• Teacher facilitates and models writing dyslexia-friendly definitions and pronounces words clearly for oral reinforcement.

5. Reflection and Wrap-up (10 minutes)

• Exit Ticket: Students write “I can…” statements about today’s lesson and one new math word they feel confident using.
• Collect tickets for formative assessment.
• Preview the next lesson focusing on applying vocabulary in math problem-solving.

Differentiation Strategies

• For diverse learners:

  • Print vocabulary cards in dyslexia-friendly fonts and with clear spacing.
  • Provide word cards with pictorial cues (e.g., symbols or diagrams)
  • Use oral explanations and peer tutoring within groups
  • Allow students to use speech-to-text tools or draw if writing is a barrier

• For advanced learners:

  • Challenge students to create their own math riddle or problem using vocabulary words.
  • Ask them to identify related synonyms or antonyms in math terms (e.g., sum and difference).
  • Invite them to explore the etymology of the words (Greek/Latin roots).

---

Assessment & Evaluation

• Formative assessment through observation during group work, oral sharing, and Exit Tickets.
• Success is measured by: active participation, correct matching of vocabulary, and appropriate use in sentences.
• Use Exit Tickets to inform reteaching or extension in upcoming lessons.

---

Additional Teacher Tips

• Encourage repeated use of vocabulary during math instruction and daily interactions.
• Keep the Word Wall visible and interactive; rotate or add new terms weekly.
• Integrate technology if available—use interactive quizzes or apps aligned with math vocabulary for reinforcement.
• To support students with dyslexia, provide audiobooks or videos explaining today's vocabulary.
