Interactive Amplify Maths lessons for elementary school.

Midway through the unit, the teacher runs a live Kahoot on the board, with Year 4 joining on the class tablets under names from Kahoot's friendly nickname generator, so no child's real name appears. Each of the twelve questions shows a fraction-wall picture or a pair of shaded shapes, and the wrong answers come from common errors, such as choosing 3/5 as equal to 2/4 because both numbers went up by one. After each question the board shows how many children chose each answer, and when several pick the add-one answer on question five, the teacher pauses the game, brings out the fraction wall and shows that adding the same number to the top and bottom changes the amount, then carries on. The teacher uses the end-of-game report to pick a group for extra fraction-wall work the next day.

Year 5 take metre sticks and tape measures to ten rectangles around the classroom and corridor, such as a table top, the door, the whiteboard, a display board, a floor tile and a PE bench top. Each pair measures four of them to the nearest centimetre, works out the perimeter and area in their books, and types the numbers into the pair's rows of a shared Google Sheet on school accounts. On the board the teacher filters the sheet to one object at a time: where three pairs give the door as 198 cm by 76 cm and one gives 189 cm, that pair goes back to measure again. Then the teacher sorts the whole table by area and again by perimeter, and the order changes. Pairs search the pooled rows for surprises and find that the whiteboard, 180 cm by 120 cm, and the display board, 240 cm by 90 cm, share an area of 21,600 cm² with perimeters of 600 cm and 660 cm, while the bench top, 300 cm by 25 cm, has a longer perimeter than the whiteboard and about a third of its area.

The teacher builds a Desmos card sort with twelve cards: 1/2, 2/4, 3/6 and 4/8, then 1/3, 2/6, 3/9 and 4/12, then 3/4, 6/8, 9/12 and 15/20, with some cards drawn as shaded fraction bars instead of digits. Pupils join with a class code and drag the cards into three groups of equal value. While they work, the teacher watches the dashboard, which shows each pupil's groups, and notices, for example, several pupils putting 2/6 with 2/4 because both have a 2 on top. The teacher pauses the class, shows an anonymised sort with that mistake, and asks pupils to prove with the fraction bars which group 2/6 belongs in before they finish.

The teacher sets up three short Wayground (formerly Quizizz) quizzes, each of ten mixed questions from the 6, 7, 8, 9 and 12 times tables. Pupils join with their first name only and the leaderboard is switched off, so nothing ranks pupils in front of the class. After each question pupils see whether they were right and the correct fact, and between rounds the teacher checks the question report for the facts with the most misses, such as 7 × 8 or 6 × 9, and spends three minutes on a strategy for them before the next round starts. At the end the teacher notes the two tables the class will practise next week.

The teacher builds a Microsoft Forms quiz with ten word problems, each with four equations to choose from: for 'Sam has some sweets, gives away 7 and has 12 left', the options are n − 7 = 12, n + 7 = 12, 7 − n = 12 and 12 − 7 = n. The wrong options are built from real mix-ups, such as reversing a subtraction or treating the answer as the unknown. Pupils work through the quiz on their own devices while the teacher watches the live summary of responses fill up. The teacher then puts up the question where one wrong option drew the most votes, asks pupils who chose it to explain their thinking, and the class changes the wording of the problem so that option would become correct.
