If your children begin to think about the next problem for them selves, then enjoy it together with them Solve the following: until they tell you what they want to do next (Figure 2). We would like you continue until the children come up with expectation. If the children expect that "555" comes next, then you just ask them: "Really?" In the mathematics classroom, the task is usually assigned teachers but, through the questioning by Figure 2 by the teachers, it becomes the children's problems. It is only then that it is regarded as being problematic by the children.
