“The editable file is why we renewed.”

Being able to change two questions for the child who joined us in January, without rebuilding the whole sheet, is worth the subscription on its own.

“Good value, and the answers are actually on it.”

Small thing, but half the free sheets online expect you to work the answers out yourself. My TA can run a group on this without a briefing first.

“Fine, though the font is small for my class.”

The maths is right and the sequence is sensible. Several of my children needed it enlarged to A3, which is easy enough but worth knowing before you print thirty.
