MULTIPLODINGO
From 7 years old.
To sharpen your children's mental arithmetic, choose a concept to work on. There's something for everyone from third grade to fifth grade: multiplication, division, squares, multiples, and review of the four operations all have their own games so you'll never get bored. The rules are very simple. They come from tried-and-tested games (mistigri, bataille, rummy, belote, etc.) and fit on one page. The games are short, and the element of chance allows everyone to win. This is a great way to round out the holiday workbook with a more playful approach, especially since the game's four characters (Kata, Padbol, Dingo, and Sacréplus) are joyfully wacky.
