Your task today is to add multiples of ten. Just like we do in school, start with the Tricky task and work your way through to check you can do each level. Most children should be able to get to Trickier and some of you may even be able to do Trickiest! You do not have to do all levels if you find them too difficult but every child does need to complete at least Tricky.
Helpful hint: remember what we learnt - it's only the tens value which is changing. For example, if there are 2 tens and you add 4 tens then there will be 6 tens and the ones haven't changed.
