Our child's teacher introduced this to our child and some others back in October. We're a bit puzzled as to why because this indie school otherwise runs a straight Year 2 maths curriculum and anyway it is not a requirement to be able to answer all tables in random order with 100% fluency and accuracy until the end of Year 4.
DC is very numerate and willing to have a go, but the scores aren't improving week after week and we're not inclined to put pressure on to improve them. Not when it's remotely a requirement for Year 2. We know that some children have completed the challenge, but that's because they've been doing Kumon maths for years.
I am thinking to contact her about this but before doing so wanted to find out if this is now a thing in Year 2.
