DD has always been quite good at maths. She did well in the 11+ and is now at grammar school but it's not a super selective one.
She seemed to be coping fine with the maths but then just before Christmas she was really poorly and had a week off school. Since then she feels she is struggling more and is especially stuck on fractions.
They recently sat a mid year maths test and she only got a Level 5c. Her predicted maths level for the end of year 7 should be Level 5a. I am worried that to gain two sub levels by July will be an uphill struggle for her.
She's asked for some maths work books which she can start using, and admits she was never sure of fractions in year 6.
Could someone recommend some friendly easy to use work books?
