Headu designs fun, high-quality games, toys, books and apps to help teach children essential skills using an innovative teaching method. Lay everything out on the table. Ask the children to look at all the subjects featured on the pieces, saying what they´re called out loud. “Horse! Tractor! Cat!...” and so on. Leave them to assemble the puzzles themselves, aided by the self-correcting pieces. If they find it difficult, give them some clues to help find the right piece, without doing it for them.
