We ALL could use a little basic skill brush-up. Over and over again I (and my students) get caught with wrong answers because of some stupid negative sign or a hiccup in a math fact.
So … try this!! Drill the basic skills! You can even include negatives by setting the parameters to go from -20 to 20 (or whatever!). You can also roll back the multiplication to just cover through the 12’s … unless you REALLY want to challenge yourself!
Or another approach: here!
Have some fun … and start a memo on your phone to keep track of your scores (but remember, you can’t compare scores unless you keep the parameters the same!).
