Cody is learning patterns within 5

Cody has been learning that 5+0=5, 0+5=5, 5-0=5, 5-5=0.  This week Cody has been learning that 4+1=5, 1+4=5, 5-4=1, 5-1=4.  Next week Cody will be learning that 3+2=5, 2+3=5, 5-3=2, 5-2=3.  I am hoping that by breaking down these family of facts and presenting each combination in separate weeks will help Cody remember.  Each week we go over what we have done the previous week.  Cody will continue to do activities that help reinforce this learning.
