Numerical and Algebraic Expressions

Description

This example illustrates the subtraction of 5 from 14 using algebra tiles. The image shows 14 yellow tiles representing the initial value, and then 5 tiles are removed, leaving 9 yellow tiles. This visually demonstrates that 14 - 5 = 9.

Algebra tiles are an effective tool for teaching numerical and algebraic expressions, particularly when introducing subtraction concepts. By providing a concrete, visual representation of abstract mathematical operations, these tiles help students develop a deeper understanding of number 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.

Presenting multiple worked-out examples is crucial for students to fully grasp mathematical concepts. Each example offers a new perspective on the topic, allowing students to see how the same principles apply in different scenarios. This repetition and variety help reinforce the underlying concepts, improve pattern recognition, and develop problem-solving skills. As students encounter various examples, they become more adept at applying their knowledge to new and unfamiliar situations, building confidence in their mathematical abilities.

Teacher Script: "Now, let's see how we can use algebra tiles to subtract numbers. We start with 14 yellow tiles, representing the number 14. To subtract 5, we simply remove 5 tiles from our group. Count how many tiles are left. You should see 9 yellow tiles remaining. This shows us that 14 minus 5 equals 9. Can you think of another subtraction problem we could solve using this method? How might this visual approach help you understand subtraction better?"
