Good grief, and I thought *I* was the only one who learned counting with those. They go back to Kindergarten, 1963-64 at Elmwood Elementary in Rosemere, QC. I remember the ones (white) and twos (red), but that's about it.
I also remember making a plasticene snake several tables long with a bunch of laughing classmates, but .. that's not important right now.
