Math spook at midnight

Embedded in a lovingly told and illustrated story about the little ghost Willi, girls and boys from the age of 4 in kindergarten and preschool learn the numbers from 1 to 12 in a playful way and learn to count. An exercise book that prepares your child for school and introduces them to mathematics and math lessons in a fun way. ­ Willi, the little ghost, doesn't have it easy. Night after night he sleeps through the witching hour at midnight. And all this just because Willi doesn't know the numbers yet and can't count properly! As soon as the old tower clock in the castle starts to strike, Willi gets very excited and tries to count the strikes every time. But everything is going haywire. ­ Let's help Willi together with the clever number-spook teacher Professor Dr. Dr. Knarz to learn the numbers so that in the future he can haunt the old castle at midnight with the other ghosts and scare people.
