This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit introduces pupils to shape tranformations: enlargements, rotations, reflections and translations both by hand and with technology.
Lesson Summary
You will learn to investigate transformations using dynamic software.
Key Notes
- Dynamic software is a tool that can be used to explore transformations.
- There are many benefits to using this tool.
- Different transformations can be carried out quickly.
Vocabulary To Learn
- Object: The object is the starting figure, before a transformation has been applied.
- Image: The image is the resulting figure, after a transformation has been applied.
- Vector: A vector can be used to describe a translation.
- Polygon: A polygon is a flat (2D), closed figure made up of straight line segments.
Common Mistakes To Avoid
- Pupils may struggle with only being able to rotate anticlockwise on Desmos.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Dynamic software is a tool that can be used to explore transformations. There are many benefits to using this tool.
2. Use this key word in a maths sentence and explain it clearly. 'Object'
The object is the starting figure, before a transformation has been applied. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may struggle with only being able to rotate anticlockwise on Desmos. Correction: Turning clockwise x degrees is equivalent to turning anticlockwise (360 - x) degrees.
