How to adapt them to each age

Ages 4 and 5

Let your child use fingers and objects on the table. Repeat the clue, speak slowly and cheer every guess, even when they need help.

Ages 6 and 7

At this age children like adding in their heads. After the answer, ask: «How did you figure it out?». Explaining the path matters more than answering fast.

Age 8

Older kids love a challenge. Ask them to invent a number riddle for you, with two clues, and guess it out loud.

Tips for playing in the car and at the table

In the car: count signs, windows and trees along the road and turn each count into a riddle: «I am the number of wheels on the car, not counting the spare. Who am I?». Great for long trips.

At the table: use grains, cutlery or little pieces of fruit. Set up a tiny problem with the food and ask for the total, always with your child seated and with no rush.

Star chart: every right answer earns a little star drawn on paper. When your child gets it wrong, celebrate the try and give a new clue.

Swap roles: after a few rounds, your child becomes the «teacher» and asks you the riddle. That is how they really learn.

To keep the fun going

After the riddles, the free coloring pages to print make a lovely break: your child can color and count how many flowers, stars or paws appear. If they like thinking while playing, Pigúiça's free game runs in the browser, with no sign-up and no ads. And for bedtime, the book Dogavios, by Lucas dos Reis Arieme, takes Pigúiça and Fofuxo to the Magic Garden, see it here.
