Practise it now

Place the layers on top of each other. Paint every square covered by either layer.

This exercise practises compose a visual transformation sequence alongside its own main skill, Overlays & ordered transformations.

It covers most of this skill rather than all of it.

A worked example

One question of the kind this skill is tested with, worked all the way through: the reasoning, and what the wrong answers are there to catch.

Working through a sequence of transformations

Take the figure through the sequence one step at a time: rotate 90 degrees clockwise, then reflect in the vertical mirror line, then rotate 90 degrees clockwise.

Each of the 3 steps acts on the picture the step before it produced, which means the sequence has to be walked in order rather than judged from the first instruction.

TransformRotate 90 degrees clockwise, then reflect in the vertical mirror line, then rotate 90 degrees clockwise

Shape picture with transform Rotate 90 degrees clockwise, then reflect in the vertical mirror line, then rotate 90 degrees clockwise made from 0 parts. Answer pictures: option 1, rotation 270 degrees, mirror x. option 2, rotation 90 degrees, mirror x. option 3, rotation 90 degrees, no mirror. option 4, rotation 0 degrees, mirror x.

  1. Option Aflipped along the diagonal from top left to bottom right
  2. Option Bflipped along the diagonal from bottom left to top right
  3. Option Cturned 90° clockwise
  4. Option Dflipped left to right

Answer: flipped left to right

How you get there

After step 1, rotate 90 degrees clockwise, the figure is turned 90 degrees clockwise. After step 2, reflect in the vertical mirror line, the figure is flipped, then turned 270 degrees clockwise. After step 3, rotate 90 degrees clockwise, the figure is flipped, with no turn. So the final figure is flipped, with no turn. Each step acts on the result immediately before it; the other options are intermediate pictures or results from changing the order.

Why the other answers tempt

Stopping part-way through the sequence gives a figure that looks reasonable but is missing a step.

If they are stuck, say this

Redraw the figure in your head after each of the 3 steps rather than jumping to the end, because one option is exactly where the sequence sits part-way through.

What this exercise is doing

Pattern Builder

Place the layers on top of each other. Paint every square covered by either layer.

This engine’s own main skill is Overlays & ordered transformations. It practises compose a visual transformation sequence alongside it, and covers most of it rather than all.

An overlay combines the covered squares from every layer. Shared squares stay covered once.

What to say if they get stuck

  1. Compare the same square in both layers.
  2. Paint it if either layer covers it. A shared square is painted once.

How compose a visual transformation sequence differs from the skills beside it

The same exercise practises several skills, and telling them apart is often the difficulty rather than the exercise itself. On this page the skill is: apply three stated rotations or reflections in order, and it stops where exactly three transformations are composed. One-step and two-step transformations have separate skills.
