Create an Anchor chart for the following: Introduction to Scaled Copies Objective: Define scaled copies, identify corresponding parts, and understand proportionality. Activity 1: Warm-Up Review fractions and multiplication/division. Question: A rectangle has sides 4 cm and 6 cm. If scaled by 2, what are the new side lengths? Activity 2: Draw & Scale Draw a triangle with sides 3 cm, 4 cm, 5 cm. Create a scaled copy using a scale factor of 2. Label corresponding sides. Activity 3: Check P...
This resource introduces the concept of scaled copies, focusing on defining what they are, identifying corresponding parts, and understanding the principle of proportionality. A scaled copy maintains the same shape as the original figure but differs in size, determined by a scale factor. Key terms such as scale factor, corresponding parts, and proportional relationships are explained clearly, along with formulas for calculating new dimensions based on scaling. The document includes warm-up exercises, worked examples, and activities that encourage students to apply their knowledge by creating scaled copies themselves. Real-world applications like blueprints and maps illustrate the relevance of scaling in everyday life.
