Example lesson context

Introduction to Fractions (Mathematics - 3rd Grade)

Materials

Gather these before class.

  • 3-2-1 reflection worksheet or journal template
  • Pencils/colored pencils
  • Optional: fraction manipulatives for reference
  • Anchor chart summarizing key lesson points

Preparation

What to have ready before students begin.

Create a template with sections labeled '3 Things I Learned', '2 Questions I Have', and '1 Connection I Made'. Display the lesson's key points on an anchor chart for reference.

Run the activity

A classroom-ready sequence from launch to follow-up.

1

After completing your fraction lesson (introducing halves, thirds, and quarters), explain the 3-2-1 reflection process.

2

Model the activity by sharing your own example:

3 things I learned: 'Fractions represent parts of a whole', 'The denominator tells how many equal parts', 'Fractions can represent division'

2 questions I have: 'Can fractions be bigger than one whole?', 'Why do we need common denominators?'

1 connection: 'Fractions are like sharing a pizza equally with friends'

3

Distribute the 3-2-1 template and give students 7-10 minutes to complete it individually.

4

Encourage students to illustrate their learning with fraction diagrams.

5

Optional sharing: Have students share one item from their reflection with a partner or small group.

6

Collect the reflections to inform your next lesson planning.

7

Begin the next day's lesson by addressing common questions from the reflections.

Differentiate

Adjust the activity without losing its core purpose.

For younger students, simplify to '2-1-1' (2 things learned, 1 question, 1 connection). For English learners, provide sentence frames. For advanced students, add a fourth category: 'How I might apply this knowledge'.

Look for learning

Use these signals to assess understanding.

Review reflections to assess individual understanding, identify misconceptions, and gather feedback on lesson effectiveness. Note which concepts need reteaching or extension.
