Merryn's copy of Fractions: adding and subtracting, numerical, already with common denominator Ready to useQuestion in MESH
Fractions already have a common denominator. Addition and subtraction 50:50 split, when subtracting, the answer is negative half the time. Students shouldn't have to worry about reducing fractions by design.

Merryn's copy of Fractions/division and multiplication, different ways of presenting the same thing (non-algebraic) Ready to useQuestion in MESH
Students seem to not realise that $\frac{a}{b}\times c=c\times\frac{a}{b}=\frac{a\times c}{b}=\frac{c\times a}{b}=a\times c \div b=a\div b\times c=c\div b \times a \ne c \div (b\times a)\ldots $ etc. This question is my attempt to help rectify this.
