Hi Natasha, I'll give you two that I like to use, and you can decide if either of them fits your needs. 1) Use each of the digits 4,5,6,7,8 once. Find which factors give you the greatest product: ___ ___ ___ x ___ ___ 2) Five Steps to Zero...a 2-player game Player A enters a 3-digit number less than or equal to 900 Player B must make the number 0 in at most 5 steps, using any of the 4 basic operations and a single digit number at each step: for example---Player A enters 703 Player B: 703 - 3 = 700 / 7 = 100 / 5 = 20 / 5 = 4 - 4 = 0 Hope these help, -Ralph, for the T2T service Thanks for visiting our online community.
