A tiling covers a whole area with tiles, with no gaps and no overlaps.
The shapes repeat in the same order.
In each new row the order shifts on by one tile.
Example: Circle, square, triangle, circle, square, triangle, ...
The row below starts one tile later, so it starts with square.
Tip: Do not look only along the row, look diagonally upwards too. The same shape sits there.
The dashed shapes show the solution.
Example
For parents
What does this exercise practice?
Continuing a pattern not just along one row but across a whole area. The child reads the missing tile along the diagonal instead of only from its row.
Common pitfalls
Children read the row from the left and count their way along. That fails when the gap is at the start of a row, because the row begins shifted. Then only the diagonal look upwards helps.
How to practice at home
Lay a tiling on the table with building blocks or tiles, each row shifted by one block. Then take one block away and let the child say which one is missing.
