Hopping mad atm. And concerned.
DC4 (Y11) proudly showed me her maths mock papers. Grade A overall
but... Question 1 on the non-calc. paper was 1.87 x 48 (or similar) and she got it wrong - worse still, she appeared to have no idea how to work it out! Says she didn't know where the decimal points went!
Same child got A*A*A in the three sciences in Y10 - generally capable of the basics in maths - or so I thought! And I'm pretty sure, if memory is correct, she could multiply decimals 6 years ago for her 11 plus exam.
She seemed not to know which method to use. I tried to butt in with helpful advice but got told off before I had even uttered a complete sentence. Not entirely sure what (half) came out of my mouth would have constituted a grammatically correct sentence anyway.
Looking through the paper it didn't seem to be a one off either.
What concerns me is that such simple maths I thought was ingrained - i.e. so well known one just couldn't forget how to do it. Obviously not.
How can a bright Y11 child just forget how to do this?
I just don't get how she could forget. (no, if you're wondering, she has not picked maths as an A level)
