Activity 01
Gallery Walk: Data Detectives
Students display the graphs they created in the previous topic. Each student has a 'detective notebook' and must visit three graphs, writing down one 'fact' (e.g., 'Blue was the most popular') and one 'surprise' for each.
What is the most common result in our data set and why might that be?
Facilitation TipDuring the Gallery Walk, post the guiding question ‘Which category is the hero of this data set and why?’ on each chart to anchor student noticing.
What to look forProvide students with a simple pictograph of classroom pets. Ask: 'What is the most popular pet in our class?' and 'If we were to get one more pet, what would be a good guess for what it might be, and why?'

Activity 02
Think-Pair-Share: The Prediction Game
The teacher shows a graph of 'Favourite Ice Cream' from a different Year 2 class. Students think about whether their own class results would be the same or different and why. They share their reasoning with a partner, using data language like 'likely' or 'more than'.
What story does this graph tell us about our classroom?
Facilitation TipFor the Think-Pair-Share, provide sentence stems like ‘I predict… because the data shows…’ to structure student reasoning.
What to look forDisplay a bar graph showing the results of a class survey on favourite outdoor activities. Ask: 'What does this graph tell us about what we like to do outside?' and 'If we planned a class picnic, what activity should we try to include based on this data?'

Activity 03
Inquiry Circle: Graph Fixers
Groups are given a graph with a 'mystery error' (e.g., the scale is missing, or the bars are not lined up). They must work together to find the error and explain how it makes the data hard to read or 'tricky' to understand.
Can we use this data to predict what might happen next time?
Facilitation TipIn Graph Fixers, assign each group a different error type so they become experts on one kind of misread before teaching the class.
What to look forGive students a small data set, for example, the number of steps taken by 5 students in one day. Ask them to sort the numbers and identify the highest and lowest number of steps. 'Which student walked the most? Which student walked the least?'

Experienced teachers start with concrete objects before graphs, using physical counters so students can literally move items to see the ‘so what.’ We avoid rushing to the abstract by building in time for students to talk through what the numbers mean in their own words. Research shows that slow, language-rich analysis beats quick answers every time.
Students will confidently name the most and least common categories, compare groups with precise language, and justify predictions with evidence from the data. They will also recognize the limits of their data set when making claims.
Watch Out for These Misconceptions
During Gallery Walk: Data Detectives, watch for students who only point to the tallest bar and declare it the ‘winner’ without comparing it to others.
Pause the walk and ask, ‘How many more people chose this than that? Show me on the graph.’ Direct their eyes to the total counts and differences.
During Think-Pair-Share: The Prediction Game, watch for students who make predictions without referencing the data they just studied.
Prompt them with, ‘Use the numbers you saw to explain why you think our next pet should be a hamster.’ Require them to cite specific bars or counts.
