These flashcards from the RETRO collection show that educational materials can be beautiful, too. The 28 cards gently illustrate the numbers from 1 to 20 and the tens from 30 to 100. On the reverse, each card shows as many elephants as the number indicates, along with adapted lyrics from the song “One Elephant Swayed.”

Children can use the flashcards to:

Arrange numbers or tens in ascending or descending order
Find the numbers that come before and after a given number
Put the elephants in order
Practise simple addition, counting the elephants to check their answers

The flashcards help improve memory and develop vocabulary, making them a highly effective educational tool. Each box contains 28–32 flashcards, along with a booklet of activity suggestions.

Children will not only learn their numbers, but also have fun singing “One Elephant Swayed.” Learning won’t feel like a chore—it will become truly enjoyable!
