Who can calculate the fastest? In this math game, players must quickly solve ten problems in the range of 10 by adding and subtracting while a sand timer runs. The task cards must be matched with the correct solution tokens. This educational math training combines fun and action. With 110 different tasks and a self-checking feature, it is ideal for preschool and elementary school students. The solution tokens fit into the holes of the task cards, providing additional stability. The game can also be played with multiple players, and afterwards, everyone compares who solved the most tasks before the sand timer ran out. Beginners can also play without the sand timer, making it perfect for preschool and elementary students who are starting with addition and subtraction. For easy self-checking, the backs of the cards are colored in the corresponding solution colors. All number tokens and task cards are securely stored in a wooden box with a sliding lid, making it easy to take along on the go.
