Logic
Finding continuation, line patterns, repetition, the missing number, circle, triangle, square, numbers and pattern, relationship, opposites, find middle part, note differences.

Word problem

The pupils learn to implement different thought processes, to develop ideas step by step, to understand different solutions and to try them again and again, to consider mistakes as clues and to ask exact questions.

• They acquire strategies to solve problems independently and to ask exact questions again and again.
• We have printed interesting solutions for children for each task so that you can see what ideas the pupils can come up with when solving the tasks before you start using them.
• For each task, you will receive more tips on how to get even weaker pupils to successfully complete the puzzles without anticipating the solution.
• Other variants offer the opportunity to differentiate.
