You could contact Book Samaritan – they might be able to get it for you….
RightStart sometimes has books etc for sale at that are gently used (ie, returned and not really used, or looked at during conferences…)
If YOU are good at math – you can do the following, which works for up to about grade 4 or 5… use the “Activities for AlAbacus” and the Worksheets for AlAbacus. It is the “original program” and has a lot of good stuff in it – but isn’t nearly as scripted, so you wwould be making more descisions about when to do what….
So – what you would need
AlAbacus (1 per student…) – I actually made some for my kids with popcicle sticks, bamboo skewers, and pony beads…
“Activities for AlAbacus”
“Worksheets for Activities for AlAbacus”
“Math Card Games Book”
“Math Cards”
Probably best bought in kits… like this http://store.rightstartmath.com/mathcardgames.aspx and then http://store.rightstartmath.com/activitiesforalabacus.aspx and http://store.rightstartmath.com/worksheetsforthealabacus.aspx
I think that comes up to $90…. which I know is still a lot – but it will easily work for Kindergarten all the way up to Grade 4 or 5…. As long as you don’t need the lessons totally scripted. And maybe you can get discounted ones or used ones….
