Bridge Builders Teacher GuideBridge Builders Teacher Facilitation Guide Subject Math: Fractions Learning Objectives Students represent fractions on a number line by partitioning 0 to 1 into equal parts. They identify the numerator (jumps from 0) and denominator (total equal parts). Materials Needed 1 Bridge Builders Board per group 1 set of Bridge Builder Cards (12 total) Game pawns (1 per student) 1 Bridge Builders Answer Key Scratch paper or dry-erase boards Quick Stats Grade: Grade 3 Group: 2-4 Students Time: 15-20 Min Focus: Number Lines Gameplay Instructions 1 Setup: Pawns on "Start". Shuffle cards face down. 2 The Turn: Draw a card. Solve the fraction problem. 3 Verify: Check Answer Key. If correct, move forward X spaces. 4 Special: "Wind" = Back 2. "Sturdy Build" = Safe space (ignore hazards). Differentiation Strategies Support Provide "Number Line Jumps" worksheet. Encourage counting spaces between 0 and 1 before identifying numerator. Challenge Name equivalent fractions (e.g., 2/4 = 1/2) for a bonus move of +1 space. Teacher Tip Students often count tick marks instead of intervals. Remind them that the denominator is the number of equal segments.
