Cindie,

Hello thank you for your message! We are excited for your family to get a RightStart in Mathematics! :)

You are right on track with your plans to have a Level B and a Level A child. Great job at deciding that! As far as the easiest way to know what to get for the children, and the most cost effective, I would advise doing the following:

Level A Starter Kit
with
A to B Add-on Kit

you will also need an additional AL Abacus.

With this you should have everything you need for a very successful school year! :) If you need anything else please let us know, we are here to help!

Make it a great day!

Cassie :)
