Successfully using reading trails in mathematics lessons. Reading competence is an important prerequisite for success in the subject of mathematics. The eight reading trail stories presented here spark interest in reading, train comprehension skills, and simultaneously convey and reinforce all curriculum content for third-grade mathematics. Your third graders follow hidden clues in the text on a reading map, apply knowledge from their math lessons, and write the correct sequence of digits to reach the goal as a reading trail. There is only one correct path. Nevertheless, reading progress is ensured, as misunderstandings or calculation errors lead to dead ends that always refer back to the last correct trail and provide content-related tips. The step-by-step approach particularly engages reluctant readers.
