Just a few minutes ago, I was reminded of how much we really need this. DS was doing his homework (number bonds) at the same rattling off multiplication tables (just showing off to me that he has picked up how to multiply by 5 - which is kinda of natural I suppose since he does know how to count by 5) Anyway, he obviously bright and has a strong grasp of math but when I looked at his homework - 50% of the numbers were backwards - his 2s were backwards and looked like 5s ... he had already erased several times.
