What to look for

Task 1 (digital skill: following an algorithm): the 5 cards are in order. A pupil who swaps Rub and Rinse can usually fix it by acting the steps out again.
Task 2 (digital skill: spotting an error in instructions): both Dry and Rinse are circled. A secure pupil can also say why: “You can’t dry your hands and then rinse them.” This is the start of debugging.
Task 3 (numeracy: before and after): all 5 circled correctly. The last 2 lines check that pupils can use before and after for their own daily routine, not just for the cards.
Task 4 (numeracy: how long tasks take): 20 bubbles coloured while counting, and the longer job ticked each time. Ask a pupil to explain one pair in words: “Sleeping is longer, it takes all night.”
