Just an FYI - although dice are referred to as number generators along with many other kinds of number generators, in my experience the term "number cube" is used for cubes with actual numbers written on them rather than as a substitute for the "dice." Depending on the game you are using them for, a six sided cube might have each of the numbers 1 - 3 twice, or it might have the numbers 3 - 9. It simply enables you to have more options than only using dice to play games. Typical math tool kids have tons of different kinds of number generators. Dice, number cubes, cards, spinners, etc. Maybe some of you live in areas that are anti-gambling and it really is a big stink, but my opinion is people are probably making a big argument out of something that is simply a misunderstanding about the math games their kids are playing. People just love to jump on the "schools are evil" bandwagon. One parent may be saying "how dare they force them to call dice number generators!" Another parent may be saying "they're teaching our kids to gamble!" And yet another parent might say "they were just playing a math game and a bully told my child that he was going to DIE!"
