Making a Pictogram of a Street Traffic Survey

Class 3 at Ysgol Pen y Bryn have a big question. Is the road outside the school busy enough to ask the council for a crossing?

While the register is called: write your name, class and date on your sheet. Look at the picture key. Find the 6 kinds of vehicle.

Starter question: How many minutes did Class 3 count for? How many vehicles are on the strip?

Your job: sort, count, draw, tell the council

You will tally the 30 vehicles, count them in a table, draw a pictogram and write 2 sentences for the council.

Tally

A mark for each vehicle. Draw 4 lines, then the 5th line across them to make a gate of 5.

Pictogram

A chart that shows data with pictures. Our pictogram uses circles.

Key

Tells you what 1 picture stands for. Today 1 circle = 2 vehicles.

LNF: Numeracy → Statistics and probability → Representing data Steps 1 to 4 are the work that gets marked

Slide 3 of 7 · Steps 1 and 2: tally, then count · Geography · Year 3

15 minutes

Step 1: sort and tally. Step 2: count and check

Start at vehicle 1. Put 1 tally mark in the right row, then cross the vehicle off. Keep going to vehicle 30. Then count each row.

Vehicle	Tally marks	Number
Vans	`\|\|\|\| \|` (a gate of 5 and 1 more)	6
Buses	`\|\|`	2

Add up all 6 numbers. The total should be 30. If not, check your tallies again.

Step 1: 10 minutes · Step 2: 5 minutes Cross off each vehicle as you tally it

Slide 4 of 7 · Step 3: draw the pictogram · Geography · Year 3

12 minutes

Step 3: draw a pictogram. 1 circle stands for 2 vehicles

How many circles? Halve the number in your table. If the number is odd, end the row with a half circle.

Cars: 12 ÷ 2 = 6 circles.

Bikes: 5 is 2 twos and 1 more, so 2 circles and a half circle.

Title: Vehicles outside Ysgol Pen y Bryn in 10 minutes. Key: 1 circle = 2 vehicles.

Draw 1 circle in each box. Start at the left so the rows line up.

Step 3 on your sheet · 12 minutes Odd number? End with a half circle

Slide 5 of 7 · Steps 4, 5 and 6: read, record, report · Geography · Year 3

13 minutes

Step 4: read your data. Step 5: record card. Step 6: tell the council

Use your table and pictogram to answer (a) to (e). Show your sums. Then fill in every field on the record card. Last, write 2 sentences for the council.

(c) model answer: 12 − 6 = 6. There were 6 more cars than vans.

Record card: Date, Tuesday 3 March 2026. Start time, 9:15 am. Minutes, 10.

Council sentence: “In 10 minutes, 30 vehicles went past our school gate.”

Step 4: 5 minutes · Step 5: 4 minutes · Step 6: 4 minutes Use numbers from your table

Supply teacher script (no subject knowledge needed)

Say aloud: “Step 4 first: answer the 5 questions and show your sums. Then Step 5: each box on the record card is called a field. Use the survey box at the top of your sheet for the date, times and place. Then Step 6: write 2 sentences for the council using your numbers, and 1 thing the survey cannot tell us.”

Quick check: (a) most: cars (12). (b) fewest: tractors (1). (c) 6 more cars than vans. (d) big vehicles 2 + 4 + 1 = 7. (e) bikes and tractors, because 5 and 1 are odd. Record card: end time 9:25 am, place the high street outside the gate of Ysgol Pen y Bryn, total vehicles 30. The card needs the date and time because traffic is different at other times, so surveys can be compared. Cannot tell us: how busy it is at home time or on other days.
