Hi nonicknames:
DD2 was much the same. Found Level 1 stuff (which is where most Y1 pupils will be at this point) very straightforward and just did the quizzes.
At some point (maybe Level 2/ Maybe Level 3) there will be a 'crunch' where the lessons will help to explain the concept. We waited until a quizz went badly wrong (shreeks from child usually good indication) - and then went to review the lessons.
The my maths lessons are good but very dry - really a series of prepared slides (some are animated) but pretty low tech compared to what is available out there.

apologies if this is repeating the obvious but there are some great free websites out there to support maths through games/ resources:
Woodland Junior school Maths Zone: resources.woodlands-junior.kent.sch.uk/maths/
Cool Maths for Kids (lessons & games): www.coolmath4kids.com/
Multiplication dot com: www.multiplication.com
Maths Champs: www.mathschamps.co.uk/#home

As you've said tons of games on my maths - sinking fast (memory game) and snaky sums (timestable practice) are great fun. You can explore games by NC Level (to help determine if they're appropriate).
