CCSSM 4.NF.3b reads as follows:
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8; 3/8 = 1/8 + 2/8; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.Here's a little fraction activity that can move your kiddos in the right direction toward that understanding. Be sure to provide manipulative support (concrete) and have students record their work with a model (representational). A suggestion for how to draw the model is shown below.

Thanks for this! I will be starting my CCSS unit on fractions after Christmas...and just reading the standards makes my head hurt! I like the way you explained this one.
