We have RightStart as well as several, more homegrown maths programs...today, after a tremendous amount of research, ordered the JonesGeniuses EL set. I spent quite a bit of time working with Chris on recommendations, and absolutely loved the fact that he spent at least 30 minutes on the phone with me making sure I was getting the proper product (he is from the UK and has extensive experience!). --they also offer a 20 percent discount to BrillKid members, which was attractive

We are looking forward to working with them!
In addition, I really like the book 'Marshmallow Math' as well as there are fantastic ideas for practical maths...and we love the Early Bird Singapore Math books. They are bright, easy to work with, and very toddler friendly. A isn't really writing yet so I work with her on them, but it has provided me with a lovely basis. They also come with a nice set of corresponding readers that A loves.
