Perimeter, area and volumes: changes in scale
Perimeter, area and volumes: changes in scale
What you'll learn
- Calculate the new perimeter and area of a 2D shape when its dimensions are scaled by a given factor, and verify the results through measurement with at least 80% accuracy.
- Explain the relationship between the scale factor and the change in perimeter, area, and volume of similar figures, using mathematical reasoning and providing at least two concrete examples.
- Solve real-world problems involving changes in scale, such as scaling up a recipe or designing a miniature model, demonstrating the correct application of scale factors in at least 3 out of 4 problems.
- Predict how the volume of a 3D object will change when its linear dimensions are altered by a specific scale factor, justifying the prediction with appropriate calculations and achieving correct predictions in at least 75% of cases.
