  • The second level contains exercises to solve a math expression of two numbers and comparison of the result with another given number.
  • The third level assumes the solving of two expressions with subsequent comparison of results.
  • At fourth level, an expression of three numbers has to be solved and the result has to be compared with another given number.
  • Fifth level assumes the solving of two math expressions – with three and two numbers respectively, with subsequent comparison of the results.
  • The sixth level is of highest complexity. Two expressions with three numbers have to be solved and the results have to be compared.

  It is recommended to start on the first level. The right pane will reflect the number of true and false answers. Once a level is passed successfully the child will strive to go ahead.
