Fraction Fairness Teacher GuideFair Share Fractions Teacher Lesson Guide & Pacing Duration 25 MIN Objective Students identify if circles, triangles, rectangles, hexagons, and squares are partitioned into equal or unequal parts by folding or coloring to "prove" their findings. Teacher Prep • Print Shape Proof Activity Sheets (1 per student). • Prepare Evidence Envelopes for each table containing 6-8 sorting cards. • Label two bins per table: "EQUAL" and "UNEQUAL". Vocabulary Equal (Same size) Unequal (Different sizes) Partition (Split into parts) TimeSectionTeacher Actions0-5mThe Cookie CrisisPresent a circle "cookie" cut into very unequal pieces. Ask: "Is this fair?" Brainstorm why it isn't fair. Introduce Equal vs. Unequal.5-10mGuided DiscoveryModel folding a paper square. "If the corners kiss and no paper peeks out, it's equal!" Show a rectangle partitioned unequally to show the difference.10-20mGroup Prove It!Tables open envelopes. Students take turns folding or coloring a shape to "prove" equality. Group discusses before sorting into bins.20-25mShow & Tell WrapTables hold up one "Unequal" shape. Students explain their proof ("It didn't match!"). Hand out activity sheets for independent practice. Table Group Management Mini-Roles The Folder: Folds the paper precisely. The Inspector: Checks if the corners match. The Colorer: Colors the parts to show space. The Sorter: Places the shape in the right bin. Differentiation Scaffold: Focus only on circles and squares. Use pre-colored shapes. Extend: Ask students to draw an "Equal" partition for the triangle—challenging them to find the middle!
