The term “tasks or problems that can be used for teaching mathematics” is referring to activities which involve solving mathematical equations or problems. These tasks require students to use problem-solving strategies, logical thinking, and application of various mathematics concepts in order to come up with a solution. This type of instruction has been found to be effective in helping learners develop deeper understanding of the material as well as the ability to apply their knowledge to real world situations.

These tasks typically involve open-ended questions and may include multiple steps; this encourages students to think critically and take initiative when approaching the problem at hand. Additionally, they often require some degree of collaboration among peers which helps cultivate teamwork skills while also providing an opportunity for debate and discourse over different approaches towards solving the task.
