Practise it now
Drag the track to play the cards and watch the outline move. Then say where corner C finished.
This exercise practises compose two visual transformations alongside its own main skill, Composing Transformations.

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.
Two transformations, one after the other
Follow the figure through both steps in turn: rotate 270 degrees clockwise, then reflect in the horizontal mirror line.
The second step acts on the figure the first step already produced, so swapping the order of a turn and a flip gives a different picture.
turned 270° clockwise
flipped, then turned 90° clockwise
flipped, then turned 270° clockwise
flipped, then turned 180° clockwise
Answer: flipped, then turned 270° clockwise
How you get there
The second step transforms the picture the first step made, not the original figure, so reversing the order lands the figure somewhere else; the options showing only one of the two steps stop half-way through.
Why the other answers tempt
Doing the two steps the other way round gives a different figure - the order in the sentence is the order to work in.
If they are stuck, say this
Do the first step in your head and hold that picture, then apply the second step to it; one option is what you get if you carry out rotate 270 degrees clockwise, then reflect in the horizontal mirror line in the wrong order.
Drag the track to play the cards and watch the outline move. Then say where corner C finished.
This engine’s own main skill is Composing Transformations. It practises compose two visual transformations alongside it, and covers most of it rather than all.
The programme is “Flip in the line y = x”, then “Slide 2 right, 3 down”. Taking the cards one at a time, a flip in y = x SWAPS the two numbers: (x, y) becomes (y, x), and no sign changes at all; and then a slide adds the same pair of numbers to every corner: (x, y) becomes (x + 2, y − 3). Corner C starts at (-2, 3) and finishes at (5, -5). The order matters as much as the cards do: each card acts on wherever the shape has got to, not on where it started, so playing them the other way round can leave the shape somewhere else entirely.
Step 1. Play it. Drag the fold track all the way across to play both cards, then scrub back and forth.
Step 2. Where did it land?. Now the question: where does corner C finish?
What to say if they get stuck
Scrub the track slowly, and back again. The pale outlines show every place the shape stopped.
Follow corner C on its own rather than the whole shape - it leaves a dotted trail.
a slide adds the same pair of numbers to every corner: (x, y) becomes (x + 2, y − 3).
Where compose two visual transformations sits in the 11+
The 11+ does not test these skills in isolation, and practising one in the wrong order wastes the practice. These are the skills the curriculum map connects this one to.
A two-step transformation may include a rotation component.
How compose two visual transformations 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 two stated rotations or reflections in order, and it stops where exactly two transformations; order matters.
Questions parents ask about compose two visual transformations
Answered from what the skill map records about this skill, not from a template. Every answer here is on the page, and the same questions are the page's FAQ structured data.
Apply two stated rotations or reflections in order. It is one of 22 named non-verbal reasoning skills in the 11+, in the transform strand, and this page carries 1 interactive exercise that practises it.
Doing the two steps the other way round gives a different figure - the order in the sentence is the order to work in. The wrong answers on this skill are built out of that, not out of random numbers, so it is worth naming out loud before your child meets it under time pressure.
Point at the next move rather than explaining the whole rule. Do the first step in your head and hold that picture, then apply the second step to it; one option is what you get if you carry out rotate 270 degrees clockwise, then reflect in the horizontal mirror line in the wrong order.
The skill map draws the line here: Exactly two transformations; order matters. A question past that line is testing a different named non-verbal reasoning skill, which is worth knowing before you spend a week practising the wrong one.
The skill map connects it to reflect a visual figure and rotate a visual figure. A two-step transformation may include a reflection component. A two-step transformation may include a rotation component. Each of those has its own page here.
Use The Transformation Deck, embedded on this page. It is the exercise the skill map attaches to compose two visual transformations, it runs in the browser with no account to make, nothing is scored, and nothing a child does here is recorded or sent anywhere. It also has its own link, so you can send it to a child without sending them anywhere else first.
