Puzzle pieces are large enough to have words printed on them. Matching pieces have matching words from different languages, for example, French and English. The better you know the words, the quicker you can find the matching pieces. To make memorization less onerous.

Not so practical in cardboard because number of words limited, but computerized version of jigsaw puzzle allows you to easily switch to new sets of words, to as many as needed.

See link for screenshot of program I wrote to do this.
