[quote=Anonymous][quote=Anonymous][quote] Understand subtraction as an unknown-addend problem. For example, subtract 10 - 8 by finding the number that makes 10 when added to 8.[/quote] The problem with this standards--other than it is a particularly difficult standard for first grade--[b]is that "understand" is not a very good standard. Hard to measure.[/b] [/quote] No. Not hard to measure. You measure it like this: 8 + ? =10 And if the student can figure out that ? = 2, then the student understands. [/quote]
