SteckLÜK - The learning game with colorful self-assessment. Featuring 30 age-appropriate matching exercises. Available with 5 card sets for kindergarten, preschool, or elementary school as an addition. It promotes careful observation, concentration, logical thinking, as well as German and math skills. Easy to use for children, with immediate solution verification, suitable for home and on the go. Here's how it works: There are two rows with 6 pictures each. One picture from the top row and one from the middle row match together. The task is to find pairs. The 6 pairs are marked with colored frames. For example, you place the blue frame on the picture in the middle row that corresponds to the blue-bordered picture in the top row. Once all pairs are found, color verification takes place. To do this, the slider is pulled down: Everything is correctly solved when the colored frames match the colored squares.
