3-Digit Subtraction Or Addition Practice!


This activity is great for hands on practice for 2nd and 3rd graders struggling with 3 digit subtraction or addition w/ regrouping!

I split my "class" into 2 groups.  2 students vs. 2 students.  They rolled their set of dice.  Set up their problem.  I had to check (at the beginning- they ended up catching on) before they subtracted to ensure the larger number was on top- to avoid any negative numbers. :)  The groups would find the difference (or sum depending on what you are practicing).  Whichever group had the largest answer won the round!  I loved watching the teams catch on to put the biggest number on top and the lowest possible number on the bottom so they can get the largest possible difference.  So fun to see the light bulb go off in their little minds. :)
