I noticed that on standard 3.NF.A.3.C that the examples of 4/4 = 1 and 3/1 = 3 are given, but do 3rd graders need to also be able to express 2 as 6/3 at this point? I didn’t see that given as an example and wanted to be sure sure I was clear on what they had to know at this point. Thanks for any information!
