Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson plan

Lesson Plan: Introduction to Probability

Subject

Mathematics

Topic

Probability

Grade/Age Group

Year 1

Duration

30 minutes

Number of Students

20

National Curriculum Alignment

Aligned with the Australian Curriculum: Mathematics (Number and Algebra, Statistics and Probability)

Objectives

• Introduce students to the concept of probability.
• Help students understand the difference between certain, impossible, likely, and unlikely events.
• Engage students in hands-on activities to explore probability through fun examples.
• Foster collaboration and communication among students.

Materials

• Colourful counters or dice (one per student)
• Probability wheel (printed on paper or cardboard)
• Whiteboard and markers
• Worksheets with simple probability questions
• A timer for the activity sessions

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Probability	5 minutes	Introduce the concept of probability using simple language. Explain terms: certain, impossible, likely, and unlikely. Use real-life examples like weather predictions.
2	Hands-on Activity: Counters	10 minutes	Provide each student with colourful counters. Ask them to sort the counters into groups, and discuss the probability of picking a specific colour. Guide them to understand likely vs. unlikely outcomes.
3	Probability Wheel	10 minutes	Distribute the probability wheel to students. Explain how they can spin it to see which outcomes are likely or unlikely. Let students take turns spinning and discussing results as a class.
4	Worksheet Activity	5 minutes	Hand out worksheets with simple probability questions (e.g., "What is the probability of getting a blue counter?"). Allow students to complete it individually.
5	Conclusion and Homework	5 minutes	Review the lesson's key points. Assign homework (e.g., identify one likely and one unlikely event at home). Collect their worksheets for assessment without presentations.

Homework

• Identify and describe one likely event and one unlikely event that they observe at home or in their environment. Encourage families to discuss probability during homework time.

Assessment

• Review students’ worksheets to gauge understanding.
• Collect homework and provide feedback to students individually.

Notes

• Ensure to create a welcoming environment where all students feel comfortable discussing their ideas and participating in activities.
• Use examples that are relatable to children, such as games or daily life situations, to illustrate the concepts effectively.
