Take three hands-up ideas, not open call-outs. Steer the class toward a question with a small tidy set of answers (favourite season, how you got to school, favourite school lunch) rather than open questions like 'favourite animal'.

Settle on one question with the class here and write it up in a corner of the board with its three or four answer options. This is the question you will type into the interactive in the Try It Together step.

Point from the summer tally row across to the summer bar so the class sees the count of 11 become the bar height of 11. Ask which bar is tallest and revoice: so summer is the mode — the answer chosen most often.

Hold out for the difference between the two pictures: the tally counts as we go along; the chart lets us compare at a glance. Then read the chance sentence in the last paragraph aloud together, stressing likely. Do not proceed until a pupil can name the mode from the chart and say the likely sentence for the next person.

Talk this one through together — pupils take turns at the board and the class agrees or corrects out loud.

Before tallying, type the question the class agreed in Getting Started into the interactive title, and type the three or four answer options over the placeholder labels so the question is captured on screen. Then take the count one answer at a time with a quick show of hands rather than reading each pupil one by one — a pupil at the board adds the tally marks in fives with the gate stroke as you count each raised-hands total. When the tally is complete, draw the bar chart on the board by hand, setting each bar height to its tally count; point from each tally row across to its bar. Watch for the gate-mark fifth stroke going across the group of four. Keep this class tally on the board and on the printed tally template — pupils will copy it and use it in the Class Challenge, so there is no need for anyone to re-survey the class on their own.

This is the practice round — pupils work on paper on their own, using the class tally they copied in the last step, while you circulate. There is no fresh survey here: the data already exists, so pupils focus on turning the tally into a bar chart, reading the mode and writing the chance sentence.

Take the steps in order, each a step harder. For the chance sentence, revoice a strong answer: most of us chose summer, so the next person is likely to choose summer too. Head off the slip of saying 'certain' — a mode makes the next answer likely, never certain.
