Per request, we developed 18 new Lessons for Pre-K kids. These Lessons expand on Lessons 6, 7 and 14 in Mac's Abacus Basic workbook, and they use the same Legends.
Lessons are laid out at 3 per page, and include Teaching Guides with answers to all Lessons. All 18 new Lessons are in this file.
If you would like certain Lessons expanded, please send us your request.
