The DASH 80 was the nick name of Boeing Aircrafts demonstration Jet Liner built in the mid 1950s that set the standards for the modern jet airliners. This super game requires you to use your math skills (no matter what level they) are to their utmost just like the pioneering designers of the DASH 80. Each round you try to use all ten dice in math equations to reach the target number for that round. Kids can start with low numbers, adults can start with 10 or higher. Roll all ten dice, 6 of which are specially numbered. 5+5=10 take off the 2 dice, then you have 2 and a 3 and a 4..... so 2x3+4 equals 10! take off those dice. Goal is to use all ten dice each round and that is where the thinking comes in! Next round you go for 9s 6+6/3 + 6 = 9 so you eliminate all 4 dice! The 6 special dice make the odds interesting and keeps one thinking of the best dice to eliminate. What is amazing is to see the kids use their math skills and come up with mathematical ideas you would not suspect and did not see yourself! Highly recommended.
