Picture Graphs

Overview

This 60-minute Friday mathematics session for Year 1 students in Aotearoa New Zealand focuses on collecting simple categorical data and representing it through pictographs. Each picture in the graph will represent one unit of data, helping students understand quantities visually. The lesson also emphasises interpreting terms such as most, least, smallest, and as many as, supporting early statistical literacy and encouraging communication using mathematical language.

Curriculum Links

New Zealand Curriculum (NZC) – Mathematics and Statistics (Year 1)

Achievement Objectives:

• Statistics Strand:

  • Gathering and Sorting Data: "Collect categorical data for one variable."
  • Using Data: "Represent data using picture graphs (for years 1–3), giving one-to-one correspondence between pictures and items."
  • Communicating: "Discuss data using terms such as ‘most’, ‘least’, ‘smallest’, and ‘as many as’."

Key Competencies:

• Using language, symbols and texts: Engage with pictographs to understand and explain data.
• Thinking: Reason about data patterns and quantities using visual representations.
• Relating to others: Share observations and listen to others' interpretations of data.

These align with the Mathematics and Statistics in the New Zealand Curriculum Phase 1 documents, focusing on data handling using methods appropriate for Years 0-3, emphasising practical and visual learning modalities .

Learning Intentions

By the end of the lesson, students will be able to:

• Collect simple categorical data through a brief survey or observation.
• Construct a simple pictograph where each picture represents one unit.
• Use terms like most, least, smallest, and as many as when discussing data.
• Interpret and answer questions based on pictographs.

---

Equipment and Resources

• Prepared pictograph templates (blank charts with categories and rows for picture units).
• Stickers or stamps for marking data units (large and colourful).
• Real objects or images representing categories (e.g., favourite fruits, pets, colours) relevant to the students.
• Whiteboard and markers for collective graph creation.
• Laminated vocabulary cards for most, least, smallest, as many as.

Cultural Responsiveness

This lesson honours Aotearoa New Zealand’s bicultural foundations and celebrates multicultural classroom diversity by:

• Incorporating Māori and Pasifika examples (e.g., using te reo Māori words for categories such as āporo for apples, karaka for oranges, or referencing favourite tāngata/whānau pets).
• Encouraging students to share data relevant to their own backgrounds (e.g., favourite foods or activities), inviting multiple languages and cultural perspectives into data categories.
• Using the concept of taonga (treasures) as a metaphor for respecting data collected about people and their choices, highlighting ethical practices in simple terms appropriate for Year 1.
• Providing vocabulary support to children in their first or heritage languages to connect informal knowledge with new mathematical terms.

All these reflect the NZC call for using students’ first languages as resources for learning and ensuring mathematics is culturally significant and locally relevant .

Lesson Outline (60 minutes)

1. Warm-Up and Introduction (10 minutes)

• Engage:
  • Start with a simple question to the class: “What is your favourite fruit/toy/colour?”
  • Collect hands-up responses, tally quickly on the board.
  • Introduce vocabulary: most, least, smallest, as many as by comparing the tallies orally.
• Explain:
  • Show an example pictograph on the whiteboard where each picture = 1 unit (e.g., 🍎 for apples, 🍌 for bananas).
  • Explain how this helps see who has the most or least favourite fruit.

2. Data Collection Activity (15 minutes)

• Whole class or small groups:
  • Use prepared categories relevant and familiar to the students (for example, favourite pets: dog, cat, bird, fish).
  • Students move around or raise hands to collect data from their friends, or the teacher collects data from the class by asking questions aloud.
  • Record results visibly on a class chart, using tally marks or stickers.

3. Constructing the Pictograph (15 minutes)

• Hands-on:
  • Distribute pictograph templates and stickers or stamps for students to create their own pictographs using the collected data.
  • Each student adds one sticker per unit counted in each category, ensuring one picture equals one unit.
  • Teacher circulates to guide correct placement and reinforce one-to-one correspondence.

4. Interpreting and Discussing (15 minutes)

• Group discussion:

  • Use the completed class pictograph to ask interpretive questions:
    • “Which picture has the most stickers?”
    • “Which has the least?”
    • “Are there as many dogs as cats?”
    • “Which animal do the smallest number of us like?”
  • Encourage students to use the key vocabulary and justify their answers with pointing and counting.

• Extension:

  • Invite students to create their own ‘I notice...’ statements (e.g., “I notice more students like cats than birds.”).

5. Conclusion and Reflection (5 minutes)

• Summarise what was learned: importance of collecting data and showing it with pictures.
• Reflect on vocabulary and expressions used and how data helps us learn about others.
• Celebrate participation and encourage students to spot pictographs or graphs in everyday contexts (e.g., TV, books).

Differentiation and Inclusion

• Use visual supports and repeated modelling for ESOL learners, including te reo equivalents where possible.
• Provide physical manipulatives (stickers, stamps) for kinaesthetic learning.
• Use pairs or small groups for learners who need additional support during data collection and graph construction.
• Offer challenge by asking students to create data statements comparing categories.

---

Assessment Opportunities

• Observe students’ ability to construct pictographs with correct one-to-one representation.
• Listen for appropriate use of descriptive terms in discussions.
• Check students’ responses to interpretation questions for understanding.
• Review completed pictograph templates for accuracy and effort.

---

Reflection for Future Planning

• Note students who need more time or different contexts to grasp ‘most’ and ‘least’.
• Plan for integrating digital tools to create pictographs as technology skills develop.
• Reinforce connections between data collected from own lives and wider community data.

This lesson plan supports Year 1 students to develop crucial foundational data skills aligned with the New Zealand Curriculum and reflects our bicultural and multicultural educational context elegantly, creating engaging, meaningful, and inclusive learning experiences .
