What could we ask the whole class today? Here are two questions: What is your favourite GAA county? and How did you travel to school this morning? One of these is much easier to count than the other. Which one has only a few tidy answers, and which one could have nearly thirty different answers?
Write both questions on the board. Take two or three hands-up answers, not open call-outs. Steer the class to notice the travel question has a small, tidy set of answers (walked, car, bus, cycled) while a favourite-county question could give almost as many answers as there are pupils.
Watch as we set up a tally chart for the question What is your favourite fruit? with three answers: apple, banana and orange.
Notice how each answer gets one stroke. When we reach four strokes for apple and a fifth person chooses it, the fifth stroke goes across the first four to make a gate of five. The banana row has a full gate of five and two more, so that is seven. 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 the class question at the top and rule a tally chart with one row per answer, ready to fill as the count is read out. 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.
This round is the practice bank — 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.
