Kūčiukai cookies are prepared and served during the winter holidays. For young people in Lithuania, they taste like Christmas. Before the start of the holiday season, German, English, Russian and Lithuanian language teachers used a recipe for this traditional dish to teach new vocabulary and improve students’ oral and written communication skills. During the technology class, learners followed the recipe to bake their own Kūčiukai cookies. In mathematics, they calculated the cost of making them. The origins of this winter tradition were discussed in civic education. Learning by doing proved to be an inclusive and engaging activity for all, including students with physical disabilities.
