Students will review introductory fraction concepts by using manipulatives to create, compare, and record halves, thirds, and quarters, reinforcing equal-part relationships through hands-on exploration.
Building a strong foundation in fractions supports future math success and real-world problem solving. This lesson’s tactile approach boosts engagement, deepens conceptual understanding, and builds students’ confidence with fraction notation.
Audience
3rd Grade
Time
30 minutes
Approach
Hands-on group exploration with manipulatives
Materials
Paper Fraction Circles, - Colored Fraction Strips, - Paper Plates, - Scissors, - Whiteboard and Markers, and - Fraction Lab Recording Sheet
Prep
Prepare Materials
10 minutes
Gather manipulatives: paper fraction circles, colored fraction strips, paper plates, scissors
Task 1: Use manipulatives to model 1/2, 1/3, and 1/4; draw and label each on your recording sheet
Task 2: Compare pairs of fractions (e.g., 1/2 vs. 1/3) using manipulatives—record which is larger and explain why
Encourage group discussion to articulate ideas about equal parts and size differences
Step 3
Cool-Down Reflection
5 minutes
Have each group share one insight or drawing from their recording sheet
Ask: “Where do you encounter fractions in everyday life?” and discuss responses
Distribute an exit ticket: draw a shape divided into 4 equal parts, color 3, and write the fraction (3/4)
Collect exit tickets and recording sheets for review
Slide Deck
Fraction Lab Fiesta
Grade 3 Math Lab Activity
• Review halves, thirds, and quarters
• Use manipulatives to explore fractions
• Record your work and share insights
Welcome students to the Fraction Lab Fiesta. Introduce yourself and review today’s objectives: modeling, comparing, and recording fractions. Point out the gradient background colors (#6BCB77 to #ABE6B9) and explain this theme represents growing understanding.
Warm-Up Discussion
• What is a fraction? (A part of a whole)
• Fold a paper plate into 2 equal parts: What fraction is each part? (1/2)
• Fold into 3 parts (1/3) and 4 parts (1/4)
• Today: Explore with manipulatives and record discoveries
Guide students through the definition of a fraction. Demonstrate folding a paper plate into equal parts at the board. Ask volunteers to name each fraction.
