About Mathdoku
What this skill is
Mathdoku (also known as KenKen) requires filling an N x N grid with numbers 1 through N so no number repeats in any row or column, while caged groups of cells must produce a target number using a given operation (+, -, x, /).
When children learn it
3x3 addition-only grids are introduced in 2nd grade; 4x4 and 5x5 four-operation grids are mastered in 4th and 5th grade.
Teaching Tips
- Fill in all single-cell cages first: these have no math operations and give immediate free numbers. Then find two-cell cages with strict pairs (like a 3+ cage in a 1-4 grid, which can only be 1 and 2).
Common Mistakes
- Repeating digits within a row or column just to satisfy a cage operation.
- Forgetting that single-cell "freebie" cages provide automatic numbers that should be filled first.
- Overlooking division and subtraction order inside two-cell cages.
