Teachatot

Teachatot is designed to help children learn simple spelling and arithmetic. Select a picture card and asking the child, whose turn it is, to find and identify the letters making up the word for the picture. Similarly, you could select a number and the child must find the numbers needed to make that total. Get the most right after an equal number of turns, and you win

All the 144 pieces interlock with each other to provide lots of word combinations and arithmetic sums.

The game was first produced in Britain in the 1950's but sank without trace. However, it has now resurfaced in Australia/New Zealand, and has been available there for some time.
