5 minutesSorting a toy box into a pictogram
Computers and tablets sort things all the time. A photo app can put all the photos of dogs in one group. Today you are the computer.
While the register is called: write your name and the date on your page. Look at the class toy box picture at the top.
Starter question: What do we sort at home or at school? Think about socks, recycling, or tidying the classroom.
Slide 2 of 7 · Sorting with one rule and key words · Maths · Year 1
8 minutesWe sort with one rule at a time
A rule could be what kind of thing it is. Another rule could be its size. Watch your teacher sort 6 things. What rule did they use?
Sort
Put things into groups. Every toy goes in one group only.
Rule
How we choose the groups: kind of toy, or size.
Pictogram
A chart made of pictures. 1 square for each toy.
Slide 3 of 7 · Task 1: sort the toys · Maths · Year 1
10 minutesTask 1: sort the toys into balls, teddies and cars
Make one straight mark for each toy. Then count your marks and write the number.
| Toy | A mark for each toy | How many? |
|---|---|---|
| Balls | | | | | | | 5 |
| Teddies | ? | ? |
| Cars | ? | ? |
Slide 4 of 7 · Task 2: make a pictogram · Maths · Year 1
12 minutesTask 2: make a pictogram on the pretend tablet
A pictogram is a chart made of pictures. A tablet can make one for us, but today we make it on paper.
1. Tick the rule we used: kind of toy.
2. Colour 1 square for each toy. Start at the left and do not leave gaps.
Balls row: 5 toys, so colour 5 squares.
How many squares will you colour for the balls? How do you know?
Slide 5 of 7 · Task 3: read the pictogram · Maths · Year 1
8 minutesTask 3: look at your pictogram
Circle the toy there is most of. Circle the toy there is fewest of. Write how many toys there are altogether.
Which row is longest? That toy is the most.
Which row is shortest? That toy is the fewest.
All the toys: count every coloured square.
Slide 6 of 7 · Task 4 and self check · Maths · Year 1
10 minutesTask 4: change the rule and sort again by size
Sort the same toys by size: big or small. Make a mark for each toy, then write how many. Are there more big toys or more small toys?
- I can sort toys into groups using one rule.
- I can make a mark for each toy and count my marks.
- I can make a pictogram with 1 square for each toy.
- I can use my pictogram to say which group has most and which has fewest.

5 minutesA computer sorts with a rule, just like you did today
Answer these together before the pages are collected.
| Question | Correct answer |
|---|---|
| Which toy is there most of, and which is there fewest of? | Most: balls (5). Fewest: teddies (3). |
| When we changed the rule to size, did the number of toys change? | No. The groups changed (7 big, 5 small) but there are still 12 toys. |
| Why is a pictogram useful? | You can see which group has most and fewest by comparing the length of the rows. |
