Keep the kit small

Blank paper, large paper marks and usual communication are enough. A local text editor can replace writing; using it does not establish spreadsheet/graph/software outcomes. No printer, ruler calibration, scissors, coins, food, paint, paid kit or trip is necessary. If children want real making/counting, an adult checks safe familiar materials, a clear surface, suitable object size and optional handling. No body data, medicine, electrical repair, wildlife handling or identifiable surveys.

Fraction parts must represent the same named whole and equal sizes/values as applicable. Repeated set items count equally; colour/shape differences are labelled so colour perception is not required. Data tables need a question, one record/unit, usable category/count rule, available records and honest unknowns. No pre-filled own response is supplied.
