Pictograms where each picture stands for 2
Statistics and probability
CCSS 2.MD.D.10England: Y2 Statistics
Objective and success criteria
Students will: Pictograms where each picture stands for 2.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Read a pictogram where each picture is 1; Count in twos
Leads to: the next skill in this area.
Materials: Squared paper for charts, Class survey data, Sticky notes for a live chart, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Read a pictogram where each picture is 1; Count in twos). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Today's weather in different towns (☺ = 1 child) sunny: ☺☺☺☺☺☺ rainy: ☺☺☺ cloudy: ☺☺☺☺☺☺☺☺☺ How many children chose rainy? → 3Prompt: Find the row for rainy.
- Count in twos. What is missing? 6, __, 10, 12, 14 → 8Prompt: Each number is 2 more than the one before.
- Today's weather in different towns (☺ = 1 child) sunny: ☺☺☺☺ rainy: ☺☺☺ cloudy: ☺☺ Which was chosen the most? (sunny / rainy / cloudy) → sunnyPrompt: Look for the longest row.
Hook · 5 min
- Take a quick class survey (favorite fruit, travel to school) and ask what the results tell us.
- Share the objective: Pictograms where each picture stands for 2. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Favourite fruit (★ = 2 children) apple: ★★ banana: ★★★★★★★★ grapes: ★★★★★ How many children chose apple?
- Step 1: 2 × 2 = 4
- Answer: 4
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- How we get to school (★ = 2 children) walk: ★★★★★★★ bus: ★★★★★ car: ★★★ How many children chose walk? → 14Prompt: Each star is worth 2, not 1.
- Today's weather in different towns (★ = 2 children) sunny: ★ rainy: ★★★★ cloudy: ★★★★★★★ How many more children chose cloudy than rainy? → 6Prompt: Work out each row in children first (each ★ is 2).
You do: independent practice · 10 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Favourite fruit (★ = 2 children) apple: ★★★★ banana: ★★★★★★ grapes: ★★★ How many more children chose banana than grapes? → 6Prompt: Work out each row in children first (each ★ is 2).
- In a pictogram, ★ = 2 children. How many stars show 10 children? → 5Prompt: Each star stands for 2 children.
Watch out for
- Forgetting to put data in order before finding the median.
- Reading a bar's height wrongly when the scale goes up in 2s or 5s.
Support and stretch
Support
- Review first: Read a pictogram where each picture is 1.
- Use concrete materials: squared paper for charts.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
