It continues to be really hard to set a level for Beast Academy. So far the difficulty has not been entirely what I’d hoped for – although I recognize that we did do multiplication already in MEP before covering it again in BA, which has meant a lot of review. (Which did at least get Alex to the point of automaticity with her times tables. By previous arrangement, she is being rewarded for this with a toy of her choice.)
Anyway, there will be days of fairly simple and straightforward problems, and then suddenly those will be followed by this:
…in which Alex learned a stunning mental math trick for squaring numbers that end in five, accompanied (at greater length in the text than you see here) by an elegant geometrical proof of why it works. And now we’ve moved on from there to finding the difference between two adjacent perfect squares. Neither of these is all that difficult to do, if you follow the Beast Academy method – but neither one feels like “third grade math,” either.
So, I don’t know. Is BA normal third grade math, or is it breathtakingly advanced? Sometimes it’s one. Sometimes it’s the other.
