Don't be afraid of tests! With this booklet all math tests can be well prepared. In the practice tests, which are closely based on realistic class tests, students can check their knowledge and evaluate themselves on a scale of points. The content is based on curricula and educational standards and includes all areas of competence in the third grade: Basic arithmetic operations, number range extension up to 1,000, factual tasks on lengths, weights and times, geometry, randomness, probability and combinatorics. Detailed and student-friendly solutions enable the children to retrace their mistakes. An overview at the end of the booklet summarizes important rules and technical terms.
