Grade 1
Translation of shapes
- Lesson Aims
The pupil will identify the properties of the translation transformation.
- Name of Model
A car
- The lesson structure
First Stage: A prepatory lesson on the topic of the reflective transformation, reflection and line symmetry,the line of symmetry in quadrilaterals, and rotational symmetry.
Second stage: The measuring tool,a prepatory lesson on the topic of the reflective transformation, reflection and line symmetry, opposite and adjacent vertices,the diagonal as a line of symmetry in quadrilaterals,rotational symmetry and translation of shapes.
- Lesson content
Translation as one of three transformations-Reflection,Translation,Rotation as studied in elementary school. In this lesson pupils will fold the model of a car and investigate the properties of translation, congruency of shape, the same distance in each translation of the shape and the same direction for each translation of the shape.
