We move beyond basic drilling and focus on visualizing the "story" behind the math. You’ll learn how to teach students to hunt for "clue words" like "join," "altogether," and "take away" to immediately identify the right operation.

IN THIS VIDEO, YOU WILL LEARN:
✅ The "Math Detective" Hook: How to use storytelling to introduce addition and subtraction concepts using playground scenarios.
✅ Visual Strategies ("I Do"): Watch how I model the "Animal Addition Adventure" to draw rabbits joining a group, and the "Toy Box Take-Away" to physically cross out blocks given to a friend.
✅ Guided Practice ("We Do"): Learn how to facilitate "Partner Power" activities where students use counters and work together to solve problems.
✅ Differentiation Tips: I’ll show you how to support struggling learners with number lines and challenge advanced students with multi-step "Teamwork Time" puzzles.
✅ Fun Fact Fluency: A look at the "Hidden Animal Puzzle" and "Color by Number" activities that keep students engaged while practicing their math facts.
