We have a whole wall of maths to look back on this year: number, measures, shape and space, data and chance, and algebra. Which of these five do you remember the most clearly? Was it the one you found easiest, the one you enjoyed, or the one that finally made sense one day?
Today we take a quick tour back through one big idea from each one.
Take three hands-up answers, not open call-outs. Keep it to a quick warm-up: you are surfacing which strand feels strongest before the tour starts, not running a discussion yet.
For each strand we will look at its key example. A key example is the one example that sums up a strand, the one you go back to when you want to remember the big idea.
Watch as we build 0.345 on the place-value mat. Look at the three columns after the point. What does each digit stand for? Tell me what the 5 in the last column is worth before we move on.
Now watch the conversion ladder. We start at 1 km and step all the way down to millimetres. Notice how each step is a times-ten step, the same idea we used in number. How many steps did we take?
Here is a shape with its fold-lines drawn in. This shape has exactly two lines of symmetry: one straight up and down, and one straight across. Look at where the two halves match exactly.
This bar chart shows the totals from a class survey. Which way of getting to school is the most common? Notice how each bar's height tells the story.
Last, the balance scales show 2x + 3 = 11. To find x, we take 3 off both sides, so 2x = 8. Then we halve both sides, so x = 4. Watch the beam settle level when x is 4.
Walk each strand aloud, one snapshot at a time. Point at the screen, do not drag, these are static. After each snapshot, pause for the quick question on screen and take one hands-up answer before moving on, so the watching class has a beat to absorb each strand.
This is an intentional five-snapshot tour, not five separate practice activities — keep it brisk, about a minute and a half per strand including the quick question.
Now we'll take a slower turn through each of the five strands together. A different pupil comes up to drive the tool for each strand on the board while the rest of the class predicts what it will show and calls out the answer to check, about two minutes per strand.
A pupil builds 0.345 on the place-value mat and reads each column after the point. The class says what each digit is worth, ending with the 5 in the last column.
A pupil steps the conversion ladder from 1 km down to millimetres. Predict first: each step is times ten, so how many millimetres is 1 km?
A pupil shows the fold-lines on the shape. The class counts the lines of symmetry and checks each half matches exactly.
A pupil reads the bar chart. Which way of getting to school is the most common? Read the tallest bar to check.
The balance scales show 2x + 3 = 11. Work the two moves on the board: take 3 off both sides to leave 2x = 8, then halve both sides to get x = 4. The beam settles level when x is 4.
This round is for talking it through together — pupils take turns at the board and the class agrees or corrects out loud.
One pupil per strand takes a quick go driving the display snapshot; everyone else predicts the answer before it is read off. With one driver per strand you have room for the whole-class prediction and a short revoice on each of the five strands inside the time. This is whole-class IWB delivery throughout — no small-group rotation around the room.
Listen for pupils naming a shared idea (the times-ten rule appears in both number and measures) — flag it now so it feeds the wrap.
In your maths copy, write one line for each strand with its key fact. Use these five headings, one under the other:
When you have all five, underline the strand you found stickiest this year.
Walk the room glancing at the five headings and the underlined strand — no marking, this is whole-class copybook practice. Help any pupil who has skipped a strand.
Pick three of the five strands. For each one you choose, work one challenge from that strand on paper, starting with the easier one and building to the trickier one. Show your working so you can talk it through afterwards. Every strand below has an easy challenge and a harder one.
Choose three strands and complete one challenge from each, working from the easier one to the harder one. Every strand has both.
Ways to start:
Stretch:
This round is the practice bank — pupils take turns at the board, check each answer, and the class confirms before moving on. Keep the board work brisk rather than over-explaining.
This is a year-end mixed-strand recap worked on paper at the seats. No single topical widget fits five strands, so the practice is the paper set below, also available as the Five-Strand Challenge Sheet for IWB-light rooms. Circulate and prompt; bring three or four answers up to the board for the class to confirm. Keep fast finishers working a fourth strand quietly rather than calling out.
Where did you spot the same maths idea showing up in two different strands? Did the times-ten rule from number turn up anywhere in measures? Did counting in equal parts show up in both shape and data?
Listen for pupils naming the times-ten rule as the bridge between number (place value) and measures (km to mm). Revoice a strong answer: so the very same rule that moves a digit left in place value is the rule that turns kilometres into metres. Head off the idea that each strand is its own separate world — the whole point of the tour is that the big ideas reappear.
Next we put several strands together in a big open investigation, where you choose how to combine the ideas you have collected this year.
Keep this brief. Reinforce that the strands are not five separate boxes — the ideas connect, and the next lessons lean on that.
