Counts vary by set: small kits can include as few as ~20 disks, many classroom sets include about 100 counters (often with ten frames), and some bundled magnetic sets list 60 counters plus an additional set of 200 counters.
Place-value dry-erase boards commonly measure around 9" × 12". Ten frames range from smaller classroom demo sizes (about 5" × 12¼") up to larger demo frames (for example, about 15" wide by 6.19" high).
Many sets include activity cards and teacher guides, dry-erase markers and erasable/writing mats, and storage solutions such as plastic boxes or carrying cases with molded trays, snap lids, or see-through panels.
Many are double-sided dry-erase or described as dry-erasable; activity cards are write-on/wipe-off, and several ten-frame products are magnetic so pieces and boards can be reused repeatedly.
Kits commonly come with storage solutions such as plastic cases or boxes with molded trays or compartments to keep pieces organized. Some base-ten and block sets also ship in a dedicated storage box to simplify classroom or home use.
