Learning Outcome(s)/Content Objectives

• Pose questions of interest and collect, display, and critically analyse data in a range of ways for a range of purposes and communicate the findings, as per the Primary School Curriculum (DE, 1999).
• Use tally marks to record data and create frequency tables based on collected information.
• Understand and apply the concept of mode in analysing simple datasets.

---

Learning Objectives

1. The child should be enabled to construct and interpret tally marks and frequency tables from gathered data.
2. The child should be enabled to use data to identify the mode (most frequent item) from a frequency table.

---

Assessment

1. Method: Formative assessment through observation during group data collection and completed worksheets analysing mode.
2. Assessment of: Accurate recording of tally marks, completion of frequency tables, and correct identification of mode.
3. To be recorded: Teacher checklist noting participation, accuracy of tally recording, and understanding of mode from worksheet responses.

Teacher Questioning

Lower Order Questions (Closed Questions)

1. How many tally marks do we add for each person/response? (I)
2. What does one group of 5 tally marks look like? (I)
3. Can you point to the mode in our frequency table? (D)

Higher Order Questions (Open Questions)

1. Why do you think tally marks are a helpful way to record data quickly? (C)
2. How can you tell from the frequency table which weather condition happened most often? (C)
3. What other ways could we display this data? (C)

Language Development Opportunities in this Lesson

• Introduction and repeated use of vocabulary: tally marks, frequency table, mode, mode value, data, survey, collect, record, most frequent, sample, question.
• Encouraging pupils to describe their data in sentences, promoting sentence structure skills related to explanation.

---

Literacy Development Opportunities in this Lesson

• Writing questions clearly and neatly for survey purposes.
• Reading instructions and questions on the worksheet related to mode.
• Oral language skills developed through group discussion and explanation of findings.

---

Teaching Methodologies

• Using cognitively challenging tasks (designing survey questions and interpreting data)
• Promoting Maths Talk (group work discussion, explaining mode and data findings)
• Emphasising mathematical modelling (data collection from real-world, weather-related questions)

---

Lesson Structure

Introduction (10 minutes)

• Stimulus: Begin with a short review worksheet from previous lessons focused on mode. Display an example frequency table and ask children to identify the mode.
• Elicit Prior Knowledge: Ask pupils to explain what tally marks are and how they are written. Recall previous use of mode.
• Share Learning Intention:
  • Today we will learn how to collect data using tally marks, organise it into frequency tables, and find out which answer comes up most often (the mode).
  • We will also work in groups to plan our own survey questions related to weather or other topics of our choice.

---

Development (35 minutes)

• Step 1 (10 minutes): Teacher gives ideas for survey questions (e.g., weather today, favourite season, types of clouds seen, number of rainy days last week). Pupils discuss in small groups (4-5 children) and choose or create their own question.
• Step 2 (15 minutes): Groups circulate around the classroom or designated area to collect answers using tally marks on clipboards or sheets. Teacher monitors and supports accurate tallying.
• Step 3 (10 minutes): Back in class, pupils transfer tally marks to a frequency table template provided by the teacher. Teacher supports the creation of frequency tables from the tallies. Pupils identify the mode and write a sentence describing their findings.

---

Conclusion (15 minutes)

• Cognitive: Groups share their data and findings with the class, explaining what question they asked, how many responses they recorded, and what the mode was.
• Social: Encourage respectful listening and questions between groups.
• Transition: Recap key vocabulary and why tally marks and frequency tables are useful in real life (e.g., weather forecasts, surveys, polls).

Universal Design for Learning

Pupil(s)	Reason(s)	Method(s)	Additional Comments
Visual learners	Need to see concrete examples	Use physical tally demonstrations; visual charts	Use coloured markers for tally groups (sets of 5)
EAL learners	May struggle with maths vocabulary	Use word walls, repeat key terms, paired talk	Scaffold sentence structures when explaining mode
Pupils with fine motor difficulties	Difficulty writing marks quickly	Allow group scribes or use tally stickers	Provide pre-made tally cards for data collection

---

The Learning Environment

Resources:

• Hard copies of the mode worksheet for stimulus activity
• Pencils, clipboards, tally mark recording sheets
• Whiteboard and markers
• Pre-prepared frequency table templates
• Chart paper for group presentations
• Weather-related images or flashcards for question inspiration

This lesson plan aligns with the Irish Primary School Curriculum (DE, 1999) and supports the development of statistical and data handling skills recommended for 3rd Class pupils. It uses an investigative and collaborative approach that values pupil voice and real-world contexts, empowering pupils to pose questions and communicate data critically.
