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 translate objects from information given in a variety of forms.
Key Notes
- It can be helpful to choose a vertex and translate that.
- Once all the vertices have been translated, the image can be drawn.
- The image and the object should be congruent.
Vocabulary To Learn
- Vector: A vector can be used to describe a translation.
- Translation: Translation is a transformation in which every point of a shape moves the same distance in the same direction.
- Congruent: If one shape can fit exactly on top of another using rotation, reflection or translation, then the shapes are congruent.
- Vertex: A vertex is the point where two or more line segments meet. The plural is vertices.
Common Mistakes To Avoid
- Students may translate vertically before horizontally.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
It can be helpful to choose a vertex and translate that. Once all the vertices have been translated, the image can be drawn.
2. Use this key word in a maths sentence and explain it clearly. 'Vector'
A vector can be used to describe a translation. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Students may translate vertically before horizontally. Correction: Remind the students that the column vectors work in the same way as coordinates.
