Confused about Math with Bigger

[thehergatts]

If I use Bigger with Singapore 2b/3a, do I need to buy the textbook for 3a or just the workbook? Thanks!!!

Textbook and workbook go together, so if you plan to do 3A during Bigger you need both text and workbook. Each day's assignment includes work from both.

For 2A/2B you would not need the textbooks. You can use only the workbooks with Bigger's daily lesson plans for the hands-on activities that take the place of the textbook for 2A/2B. For 3A/3B (and every level above), you do need the textbooks plus workbooks, and there is a schedule in the appendix of Bigger (and the higher level guides) for that.
