We have assigned the tasks into 3  age levels of students:

  • task A for 6-10 years olds;
  • task B for 10-14 years olds;
  • task C for 14-18 years olds.

These are only suggestions,  the usage depends on the knowledge level of the students.

Feel free to download, try them out and adapt them to your own practice!
