Can you explain whether numerical expressions using order of operations with exponents belong in 6.EE.1 or 6.EE.2c since order of operations with exponents is discussed in detail within 6.EE.2c. For instance 5 – (3+1)^2 -2^3
The progressions seem to call out some numerical expressions and specifics about order of operations in 6.EE.2c. Should 6.EE.1 be simpler type of expressions not relying on the methods of order of operations?
Also, can the base in 6.EE.1 of a exponential number be a fraction or decimal?
Thank you!The standards set expectations for what kids should know at the end of the course; they are not markers for particular topics along the way. The sort of question you ask here comes up when people try to arrange the standards into a curriculum, but there are many cases where that doesn’t really make sense (this one, for instance). That said, assessment writers have to make decisions about what sorts of questions belong to which standards, and I think your suggestion here is reasonable that 6.EE.1 would be assessed with simpler expressions than 6.EE.2c.
As for your question about bases, I don’t see any reason to restrict the base to whole numbers.
