If you just want more practice some great free websites include:
Woodlands Junior Maths Zone: links to great games under various headings: resources.woodlands-junior.kent.sch.uk/maths/
Multiplication dot com has resources/ instructions and games to help support learning the times tables: www.multiplication.com/ - click the grey tabs and explore.
If your DD is find learning times tables tricky - we found the free downloads from Timez Attack very useful: www.bigbrainz.com/ - your child will be tested and the programme will start from where they are at (i.e. if they know x2/ x5 and x10 - it won't drill those too much but will move on to other tables). You are cast as a young ogre and search through a dungeon or a castle solving multiplication problems (presented both as multiple additions you count up - i.e. 4 x 8 is shown as 4 blocks of 8 and then counted up 8, 16, 24, 32 - and as traditional vertical multiplication problems you just type the answer in for). Every so often you have a quiz to review what you are doing with a medium-sized ogre and at the end of a level you have a quiz with the BIG OGRE. Once you've completed all tables you have a test which either sends you back for more practice and you pass. It can be very stressful - but that helps improve speed of recall I think.
There are more expensive versions with more platforms to explore - but we found the free version worked. There is also a division version (so inverse multiplication skills - 36 divided by what is 9?

If the issue is that at core the basic calculation skills are shaky and you think your daughter could benefit from more structured practice many of us here, including me, have posted our praise for various on-line tutorial programmes:
mathsfactor: www.themathsfactor.com/
Komodo maths: komodomath.com/
Mathletics: www.mathletics.co.uk/
maths Whizz: www.whizz.com/
These are subscription services of varying prices - but they do present the techniques and structure what is learned, taking some of the work of figuring that out off your shoulders.
We used mathsfactor to great success for both DDs (Y7/ Y5) and I would heartily recommend it, especially for girls. Carol Vorderman's videos explaining what to do are very clear, I like the programmes structure (some do complain it can be slow paced - but you can select which lessons and move along if it's really dragging - however I am a complete-ist and had my girls do it all). We all found Carol Vorderman's presenting of maths incredibly enthusiastic and she seemed to make maths fun, which becomes contagious.
--------
If your school uses My Maths - you can go into the programme and select topics from the level your child is working and do the lessons/ practice tests for more practice free of charge. School subscriptions run all summer - so you can keep on using it now and then over the summer to keep those maths juices flowing.

Khan Academy: www.khanacademy.org/math is entirely free and has now prepared work for primary aged pupils in the US. US grades are not = to UK. Grade 3 would be the Equivalent of Year 2, because we start school slightly later than the UK. However, at some point they do converge (?Year 5/ Grade 5 or thereabouts).
---
Later on - KS2 Upper (Y5/6) BBC Bitesize KS2 has all sorts of maths games for practice and is entirely free: www.bbc.co.uk/bitesize/ks2/maths/ - but that is likely to be too challenging now for a Y3 pupil.
------------
With all of this you need to do a bit of homework first - have an explore and see what is most helpful. I would advise including your DC in any choice of what to do - if they like the look of it they're more likely to do it/ use it.
