Grade 2 magnet test: comparing every pair's sorted objects on a Padlet wall

Grade 2 (Year 3, age 7 to 8) · 40 min · 1 tablet per pair

Each pair gets a tray with a paperclip, a plastic spoon, an eraser, a brass key, an iron nail and a 1p coin, and the teacher has quietly given some trays a coin from before 1992 and others a newer one. Pairs test each object with a bar magnet, make two piles, and post one photo of each pile to the magnetic or non-magnetic column of a class Padlet. The teacher scrolls the columns on the board and stops at the 1p coins, which appear in both columns. Two pairs retest their coins at the front, and the class reads the dates to find that newer coins are copper-plated steel. Photos show the objects on the tray, with no faces or names.

Why this is Interactive Amplify

Children test objects and sort them by what they observe, working with given materials rather than making anything new. Padlet puts every pair's piles side by side on the board as they are posted, so the teacher can find the coin that splits the class and turn that disagreement into the next test.

Compared with

Pairs sort objects into two hoops on their table and report back by hands up.

Watch out

If the wall is scrolled without anyone comparing piles or retesting, nothing the wall adds is used, anything that records the piles could carry the task, and this is Interactive Replace.
