Translation | I Do, We Do, You Do | Year 8 Maths | Print Free

Teach translation with this editable, 71-slide Year 8 maths PowerPoint. Pupils identify corresponding vertices, apply horizontal and vertical movements, describe translations and recover original coordinates. Every vertex moves by the same amount, preserving size, shape and orientation.

Designed for print-free teaching: pupils write coordinates in exercise books or on mini-whiteboards. They do not need to copy grids, draw transformed shapes or use printed worksheets. Projected diagrams support understanding, and visual answer checks show the original shape alongside its image.

WHAT IS INCLUDED?
• One editable PowerPoint containing 71 slides.
• Six retrieval questions with grouped answers.
• Six prerequisite questions with grouped answers.
• Illustrated vocabulary covering translation, object, image, vertices, corresponding vertices and orientation.
• Teaching examples showing what a translation preserves.
• Six matched I Do/We Do examples with worked answers.
• Twenty AFL questions, each immediately followed by its answer slide.
• Twenty-four minimally different practice questions, with coordinate answers and visual checks.
• Eight Developing, eight Secure and five Greater Depth questions, plus a two-part Super Challenge, on one page.
• Answers for every differentiated question and both challenge parts.

MODELLING AND GUIDED PRACTICE
The six examples form three matched pairs: (1) with (4), (2) with (5), and (3) with (6). Pupils begin with horizontal translations, combine horizontal and vertical movements, then undo a translation to recover the original vertices. Worked examples show the changes and resulting coordinates.

PRACTICE AND PROGRESSION
The main practice page contains 24 questions using one displayed triangle. Controlled changes connect rightward and upward movements with leftward and downward movements. Pupils return to the original triangle for each question and list the new coordinates in the same vertex order.

Developing uses a different triangle and eight translations. Secure includes describing a translation from coordinates, recovering originals, transferring a movement to another point, combining translations and checking an image vertex. Greater Depth asks pupils to explain inconsistent movements, incomplete vertex checks, preserved area, the order of translations and fixed points.

SUPER CHALLENGE
Pupils find a translation that places a triangle against both axes without crossing them, then justify why it is unique. A second condition places two vertices on the axes and the remaining vertex in the third quadrant. Worked solutions explain how the coordinate constraints determine the movements.

CLASSROOM PRESENTATION
Grids use square cells, stronger grid lines and coordinate numbers beside the axes. Practice answer diagrams show one image at a time alongside the original. A divider separates the Super Challenge from the other levels.

Suitable for Year 8, KS3 consolidation, tutoring and revision. Topic reference: M139.
