Ready-to-use classroom activity
Students number off in groups, discuss a question together, and then the teacher calls a number to share the group's answer.

Example lesson context
Gather these before class.
What to have ready before students begin.
Create 8-10 equivalent fraction problems of varying difficulty. Arrange students in heterogeneous groups of 4. Prepare number cards (1-4) for each group. Set up visuals and manipulatives for fraction work.
A classroom-ready sequence from launch to follow-up.
Introduce or review equivalent fractions with visual models.
Organize students into groups of 4 (adjust as needed for class size).
Assign each student a number (1-4) within their group:
Students should remember their number throughout the activity
Consider giving students number cards to wear or place on desk
Explain the process:
Teacher poses a question about equivalent fractions
Groups discuss and ensure EVERYONE knows the answer and can explain it
Teacher randomly calls a number (1-4)
Students with that number stand and one is selected to answer
All groups held accountable for the selected student's answer
First round example:
Display question: 'What fraction is equivalent to 2/4? Show two different ways to prove they're equivalent.'
Groups discuss for 2-3 minutes, using manipulatives if needed
Each group records their answer and solution methods
Teacher calls 'Number 3'
All number 3 students stand, and one is randomly selected to present
Other groups indicate agreement/disagreement with thumbs up/down
Continue with 5-7 more questions of increasing complexity:
Finding equivalent fractions using multiplication/division
Determining if two fractions are equivalent
Creating visual models showing equivalent fractions
Real-world applications involving equivalent fractions
Group processing: After several rounds, have groups discuss how well they ensured all members understood the content.
Adjust the activity without losing its core purpose.
For struggling students, provide fraction models and reference sheets. Keep track of which numbers have been called to ensure all students participate. For advanced groups, include more complex problems involving equivalent fractions with variables or word problems requiring multiple steps.
Use these signals to assess understanding.
Monitor group discussions to assess collaboration and explanation quality. Note which students struggle when their number is called. Use final problems as formative assessment of equivalent fraction understanding across the class.
