Topic

Numerical and Algebraic Expressions

Description

This example demonstrates the addition of 7 and 12 using algebra tiles. Two groups of yellow tiles, one with 7 tiles and another with 12 tiles, are combined to show a total of 19 tiles. This visual representation helps students understand the concept of addition with positive integers.

Algebra tiles are an effective tool for teaching numerical and algebraic expressions. They provide a concrete, visual representation of abstract mathematical concepts, making it easier for students to grasp addition, subtraction, and more complex algebraic operations. By manipulating these physical or digital tiles, students can develop a deeper understanding of mathematical relationships and problem-solving strategies.

Exposure to multiple worked-out examples is crucial for students to fully comprehend mathematical concepts. Each example reinforces the underlying principles and demonstrates different scenarios where the concept can be applied. This repetition helps students recognize patterns, develop problem-solving skills, and build confidence in their mathematical abilities.

Teacher Script: "Let's look at how we can use algebra tiles to add numbers. In this example, we have 7 yellow tiles in one group and 12 yellow tiles in another. When we combine these groups, we can easily count the total number of tiles. This visual method helps us see that 7 plus 12 equals 19. Can you think of other numbers we could add using this method?"
