This collection contains 4×4 and 9×9 Sudoku and balance-scale comparison puzzles. Choose by whether the learner can understand and check each printed condition, rather than by age. In Sudoku, fill rows, columns and 2×2 or 3×3 boxes without repeating a number. In the scale puzzles, the lower side is heavier; connect the comparisons to find the weight relationships between objects. These are practice activities, not standardized intelligence tests or diagnostic tools. The timetable activity adds preparation slots and periods when a room cannot be used.
Not sure where to begin? The Sudoku guide below walks through starting with easier grids, scanning rows and columns for the only possible number before ever guessing, and when a child is ready to move up to harder puzzles. The maze and focus guide covers a related skill — sustained attention — and how to raise difficulty as your child's patience for multi-step problems grows.
