So, if we're going to buy expensive schemes to teach children maths, can the providers please make sure that the activities make sense and aren't, you know, wrong or anything.

Say the number: four thousand, seven hundred and eighty-three. Ask children in their groups to write this in figures. Write it on the board to check: 4783. What is the lowest number you can add so that all four digits change? Allow 3 or 4 minutes to try this, then take feedback. (1111 is the lowest number that can be added so that all four digits change, making 5894.) Will this always be the lowest number? Can you find a 4-digit number where all four digits can be changed by adding a lower number? Ask children to explore this, starting by finding different types of number (e.g. multiples of 10 or 100) where a lower number can be added. Ask them to write some general rules (e.g. if the number ends in 9, then the lowest number that can be added to make all four digits change is 1101.)


Just.... No, don't do that! I can't even think of an interpretation that might make that make sense.

So when they say 1111, they actually mean 229? Well... probably not. Your valiant attempt to salvage some sense from this founders on the rock of its fundamental gibberishness. As does everybody else's, of course. If none of us can tell for sure what the bloody hell they're trying to get at, that does suggest at the very least that they've been a tad unclear...

Emptied of expectation. Relax.
