DD is in yr 5 and is doing extea maths after school once a week. (to catch up)
She was given the 'Power of 2 Maths' book which you have to do with an adult.
The premise is that you work together on the book to improve speed on mental arithmetic.
The teacher said we had to do it every night but we haven't had time this week due to me and DS being ill(plus she has normal maths, literacy and project homework)so we only did it 3 times.
Teacher was v. cross and complained that it's an expensive book and someone else could have been using it. (in quite a rude way)
She's now taken the book away from DD and when I tried to explain that we haven't had time she said 'it only takes 2 minutes to do it!' in a totally dismissive way.

I felt quite reprimanded!
