Der Igel der wissen wollte, wie viele Stacheln er hat

When the hedgehog wakes up from his winter sleep and starts to groom himself, one of his spines falls out. Startled, he wonders, "How many spines do I still have on my back?" In the forest, he encounters various animals, including a rabbit, a fox, and a deer, and asks them for advice – but can anyone count all his spines? This picture book introduces a number from 1 to 10 on each page. Through diverse counting opportunities, it supports children aged 3 to 5 in acquiring counting skills – the first mathematical learning content. It also addresses the decomposition of numbers, an important learning step in the development of number concepts.
