Texas Instruments Little Professor (1976)

Complete and in very good condition, this Texas Instruments Little Professor dates from 1976 and was a colourful attempt to make maths more fun. Despite looking like a calculator, these early models rather bizarrely lacked that functionality, instead solely providing mathematic puzzles which vary from simple arithmetic to number finding games, led by the included activity cards.

This one is in fully working order, has the complete set of cards, and the box isn’t in bad shape either.
