The video tutorial is aimed at fifth-grade students and focuses on problem-solving with fractions. The teacher introduces the concept of working backward as a strategy to solve problems involving addition and subtraction of fractions. Two example problems are presented: one involving skiing distances and another about cutting a wicker strip. The teacher guides students through the process of setting up equations, finding common denominators, and checking the reasonableness of their answers. The lesson concludes with a reflection on the learning process.
