Today we learn how to pose a data question the class can tally. A good question has only a few tidy answers, not dozens.
Watch one worked example. We want to know about morning travel. A weak question is What is your favourite thing about the journey? because answers could go on forever. A strong question is How did you travel to school this morning? with only a few answers: walked, car, bus, cycled. That small set is easy to tally.
Now look at two questions on the board: What is your favourite GAA county? and How did you travel to school this morning? Which one has only a few tidy answers, and which one could have nearly thirty different answers?
Board the weak vs strong pair first and talk it through as the worked example: favourite-thing-about-the-journey (endless answers) beside How did you travel (walked, car, bus, cycled). Point out we chose the travel wording on purpose so the answer set stays small.
Then write the two lesson questions. Take two or three hands-up answers, not open call-outs. Steer the class to notice travel has a tidy set while favourite-county could give almost as many answers as pupils.
Slip to watch: pupils may still offer wide questions (favourite animal, favourite colour). Nudge them back to few fixed answers before moving on.
Look at this tally chart for the question What is your favourite fruit? with three answers: apple, banana and orange.
Notice how each answer gets one stroke. The apple row shows four single strokes. The banana row has a full gate of five and two more, so that is seven. The fifth stroke goes across the first four to make a gate of five. Counting in fives makes the rows quick to read.
This is a static display snapshot — point at each row and count aloud rather than tapping. Walk each row slowly:
Emphasise the fifth stroke goes across as the make-or-break move so the count stays in fives.
Today we explore one real question together: What is your favourite school subject? with the answers Maths, English, PE and Art. We go round the room and each pupil says their one pick out loud. As each pupil names their subject, we add one mark to the matching row on the board, making a gate-mark every fifth stroke. Let's check our rows count up in fives.
This round is for talking it through together — pupils take turns at the board and the class agrees or corrects out loud.
Go round the room so every pupil states one subject; with the whole class spread across four rows, the popular rows will pass five several times, so each rotating pupil is likely to draw a fifth stroke. Watch for the fifth-stroke slip: many pupils draw five separate strokes instead of crossing four. Pause at every fifth mark and ask does this stroke go across? Rotate four pupils through adding marks so several get a turn at the gate.
In your maths copy, write 'How many of us...?' at the top and rule a tally chart with one row for each question (Brought a lunchbox, Has a sister, Likes brown bread, Walked to school), ready to fill as the yeses are counted. Leave plenty of space along each row for your marks, and remember to cross every fifth stroke to make a gate.
Walk the room glancing at whether each row has a clear label and enough space — no marking, this is whole-class copybook practice. Help anyone who has squashed the rows too close to count later. Pupils who find ruling their own rows tricky can use the pre-ruled tally template printable instead, so they can focus on the marks rather than the lines.
Today we run quick whole-class tallies. Each question is a how many of us...? question, and the count of yeses fills one row on our chart:
For each question, every pupil who answers yes adds one to that question's row, so each question gives us one row. As the rows fill across the whole class, our gate-marks really earn their keep.
These are the practice questions — pupils take turns at the board, check each answer, and the class confirms before moving on. Keep the board work brisk rather than over-explaining.
All four questions are parallel whole-class yes-questions, and each adds exactly one row of yeses to the chart. With the whole class answering, the yes-counts will often pass five, so the gate-marks matter most — keep stopping to count rows in fives so pupils feel why fives are faster than ones. Rotate a different pupil to record each round.
Why is What is your favourite animal? harder to tally than Do you have a pet — yes or no? What makes a question easy or hard to count?
Listen for pupils naming the number of possible answers as the deciding thing — a yes/no question has two tidy rows, a favourite-animal question could need a new row for nearly every pupil. Revoice a strong answer: so the fewer the answers, the fewer rows, and the easier it is to tally.
Next we turn our tally marks into numbers in a frequency table, so we can see at a glance which answer won.
Recap the gate-mark as the day's big idea. Flag forward to frequency tables without going into detail.
