In the grid each child is on the left and each number is on top.
Take one clue at a time. A clue like "Mia does not have the 14" rules out one square.
If only one square is left in a row, that is the answer - and no other child can be in that column.
There is a box at the end of each row. Write the number you found for that child in it.
Example
For parents
What does this exercise practice?
The logic grid practices pure reasoning: deriving something certain from "not" statements, with no calculation at all.
Common pitfalls
Children often want to guess instead of checking off. It helps to read each clue out loud and put it into the grid straight away before moving on.
How to practice at home
Act it out with three soft toys and three slips of paper: who gets which slip? Say the clues first, then hand them out.
