16. Examples of Inequalities = Greater ThanLess Than Equal To ><

17. Examples of Greater Than 6 2 1510 2322 4 + 32+2 10+812+2 25-611-5

18. Examples of Less Than 910 2125 1418 20 - 921-8 6+910+5 5-25-1

19. Examples of Equals To 12 = 1215 + 6 = 19 + 2 25 = 25 20 - 6 = 18 - 4 4 = 4 13 + 8 = 11 + 10

20. Play The Game! Each student is going to play the Inequalities Game individually. Make sure to work quietly and raise your hand if you need assistance.
