Math Dice Jr. Game
For younger players, check out math Dice Jr. which only has one 12-sided die (which is rolled to get the "Target Number") and five 6-sided scoring dice which you add or subtract to reach the "Target Number."
This simple dice game is a fun way to improve mental math skills. The game includes three standard 6-sided dice, two fancy 12-sided dice, a travel bag, and an instruction booklet. Rules of the game are simple. First, you roll the two 12-sided dice and multiply the two numbers to get a "Target Number." Then you roll the three 6-sided dice and try to combine those numbers in any way (addition, subtraction, multiplication, division, powers, roots, etc) to match or get as close as possible to the "Target Number." Play solo or with as many people as desired.
