Prefix Power: Substitute Guide
100% Tech-Free
Substitute Note & Core Objective
Today students learn that a prefix is a word part added to the beginning of a base word that changes its meaning. All materials are pre-printed. Keep visual cues prominent and encourage students to use finger-tracing on the anchor chart.
Materials Needed Today
✓ Prefix Anchor Chart (1 per student/display)
✓ Prefix Color Breakdown Worksheet
✓ Prefix Cut & Paste Activity (Scissors + Glue)
✓ Blue & Yellow Highlighters / Crayons
45-Minute Lesson Pacing & Script
1. Hook & Train Visual Analogy (10 min) Whole Group
Say: "Imagine a train! The engine is in front. In word building, a prefix is like the engine—it attaches to the FRONT of a base word to give it new power!" Prefix Anchor Chart . Choral read the 4 target prefixes: re- (again), un- (not), dis- (opposite/not), pre- (before).
2. Guided Color-Coded Breakdown (12 min) Guided Practice
Distribute the Color Breakdown Worksheet . Model item #1 under doc camera or on board: color prefix BLUE, base word YELLOW. Emphasize how re + play = replay (play again).

Pass out scissors and glue sticks. Students cut the 6 prefix cards and glue them onto matching base words. Circulate to check that prefix tiles stay on the left side.
