## Topic

Numerical and Algebraic Expressions

## Description

This example demonstrates solving the equation x + 3 = 5 using algebra tiles. The image shows green tiles representing the variable x, yellow tiles representing positive integers, and red tiles representing negative integers. By creating zero pairs and isolating the variable, the solution x = 2 is visually represented.

Algebra tiles are an effective tool for teaching numerical and algebraic expressions, particularly when introducing equation-solving concepts. By providing a concrete, visual representation of abstract mathematical operations, these tiles help students develop a deeper understanding of algebraic relationships. This approach is especially beneficial for visual and kinesthetic learners, as it allows them to physically manipulate the tiles and observe the outcomes of different operations.

Exposing students to multiple worked-out examples is crucial for reinforcing mathematical concepts. Each example presents a unique scenario, helping students recognize patterns and develop problem-solving strategies. This repetition and variety of examples contribute to a more comprehensive understanding of the topic, enabling students to apply their knowledge to different situations with confidence.

Teacher Script: "Let's explore how we can solve the equation x + 3 = 5 using algebra tiles. We'll start by representing x with a green tile, and 3 with three yellow tiles on one side of the equation. On the other side, we have 5 yellow tiles. To solve for x, we need to remove 3 yellow tiles from both sides. What do we have left? That's right, one green tile equals two yellow tiles, showing us that x = 2. How does this visual method help you understand the steps in solving equations?"
