Writing charts for Japanese children

[Emma]

I've heard of writing charts that Japanese children have that they use half the time for reference when learning katakana/hiragana and the other half of the time they use it to lean on when writing. They normally have pictures on them - Anime/Manga characters, pop stars, etc.

But what are they called?!?

Thanks a lot!
