Sorting and counting, bar graphs, pictographs, line plots, pie charts and averages, Venn diagrams, judging claims about data, and probability.
Practise sorting and counting a jumble of pictures by kind: the first step towards data and graphs. New pictures every time, with a solution video.
Practise bar graphs: build bars from a tally chart, or read a graph to answer how many more, fewer or in all. New data every time, with a video.
Read a pictograph with a key and answer questions like 'how many sold at least 3?'. New data every time, with a narrated solution video.
Practise making a line plot from measurements in halves and quarters of an inch: one X for each. New measurements every time, with a solution video.
Practise finding the average (mean) from a bar chart, then how many are above and below it, plus the highest, lowest and range. With a video.
Practise reading pie charts labelled in percentages: how many prefer soccer out of 1,200 students? New surveys every time, with a solution video.
Practise reading pie charts labelled with counts: what percentage chose an option, and how many didn't? New surveys every time, with a solution video.
Practise two-circle Venn diagrams: in a class of 30, 18 have a pet, 15 a bike and 3 neither, so how many have both? With a narrated solution video.
Practise probability: what is the chance of at least 1 five when 2 dice are tossed? Coins and dice, answered as a fraction.
Eight tails in a row: is heads due? Practise chance with coins, dice and spinners after a streak. Free, a new question every time, with a video.
Practise probability by listing pairs: pick 2 of 5 boxes, 1 with a prize. Tick the pairs that fit, count them, and write the chance as a fraction. With a video.
Practise reading survey tables critically: is each claim true, false, or not something the data can tell you? New surveys every time.
