Algorithms to sort and classify shapes: a week of ready-to-teach maths
Five days of lessons for Year 7 Space. Print this pack and the week is prepared.
AC9M7SP04
design and create algorithms involving a sequence of steps and decisions that will sort and classify sets of shapes according to their attributes, and describe how the algorithms work
Start here: five minutes to Monday
- Skim the week at a glance.
- Print the five days (plan + worksheet each).
- Cut out the card sheet once.
- Open the free interactive unit on your board.
- Teach from the plan.
On the board
On-screen pictures: “A classification decision tree”, “The algorithm as steps”, “Trace the algorithm step by step”, “Sorting a batch into bins”, “The order of questions matters”.

Day 1 · Teacher planDay 1 of 5
A classification decision tree
Children practise “A classification decision tree” with talk, the board picture, and a short worksheet. About 40 minutes.
We are learning to
- explain a classification decision tree in Year 7 words,
- use the board picture to check thinking,
- record an example on paper.
Success criteria
- I can show one example of today’s idea.
- I can say the idea in a short sentence.
You need
- interactive unit open on “A classification decision tree”,
- worksheet (next sheet), one per child,
Lesson flow (about 40 minutes)
| 5 min | Warm-up Ask: “What might help us today?” |
| 10 min | On the board Open “A classification decision tree”. Ask: “What changed on the screen?” |
| 15 min | Worksheet Children complete the day sheet. |
| 10 min | Share Ask: “In one sentence, what was today’s idea?” |
On the board
Leave “A classification decision tree” on screen for the main block.

Watch for
- Skipping the board -- bring them back to the picture.
- Correct answer with no explanation -- ask how do you know?
Answers and look-fors
- Meeting the idea sounds like a clear sentence about a classification decision tree.
