We have used this series for several years now and could not be more pleased with the results. Each week, my two oldest children work through one puzzle in their current level. Our oldest son is using B-1 and our oldest daughter is using A-2. Both workbooks are filled with 15 puzzles. Each puzzle has a grid and clues. The child must read all the clues and fill in the grid to discover the solution. For my family these workbooks are a hit. Typically, when the children complete one puzzle, they ask to do another. I'd say that means they are enjoying this 'mind bending' activity!
