Put addition and/or subtraction skills to the test with this fun and simple center!
This center has 2 sets of directions, one for adding 2-digit numbers, one for subtracting.
-Roll two 2-digit numbers and write them down.
-Add or subtract the numbers together in the standard way.
-Have their partner do the same problem, but with a drawing.
-If they get the same answer, they both get a star!
-If they did not get the same answer, they need to find out what went wrong and fix it.
-Then students switch jobs. Students continue until center timer runs out to see how many stars they can get!
For advanced students, have them roll two 3-digit numbers.
