Skills
- compare (attributes of a shape and its dilation on a coordinate plane) #dok2
- contrast (attributes of a shape and its dilation on a coordinate plane) #dok2
- analyze (differences and similarities between original shapes and their dilations) #dok3
Learning Targets
- I can describe the attributes of a shape and its dilation on a coordinate plane. #dok1
- I can identify similarities and differences between a shape and its dilation on a coordinate plane. #dok2
- I can compare and contrast the size, orientation, and position of a shape and its dilation on a coordinate plane. #dok2
- I can analyze how dilations affect the attributes of two-dimensional shapes on a coordinate plane. #dok3
Big Ideas
- Dilations change the size of a shape but not its shape or proportional relationships on a coordinate plane.
- Comparing and contrasting original shapes to their dilations helps understand proportional relationships and transformations in geometry.
Essential Questions
- How does dilating a shape change its attributes compared to the original on a coordinate plane?
- What aspects of a shape remain constant and what changes after a dilation?
- How can you compare and contrast a shape's position, size, and orientation before and after a dilation?
- Why is it important to analyze the attributes of shapes and their dilations in geometry?
- In what ways do dilations demonstrate proportional relationships on a coordinate plane?
