[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Your daughter has probably done MANY practice problems like the one you shared and should know to go to the most exact answer.  I understand where you are coming from, but she can complete 4.5 pots, not just 4.  In my class today (compacted 5/6), one question asked if a child earns $5.50 per hour babysitting, how many hours would it take to earn $52.25.  One of the children answered 10 hours with the same reasoning you gave above, so we discussed why that was not the most accurate response.  Like it or not, this is what is now expected from the children.[/quote]

I'd agree except for the way the word "complete" was used in the problem. In your example, if the question was, "Larla is paid $5.50 for each completed hour of babysitting. How many hours would it take to earn $52.25?"[b] I'd answer 10.[/b]

Answering 10 on the question given would have been incorrect, which is my point.  The OP's child has done examples like this with similar wording.  Although it might sound strange, parts of pots and parts of hours need to be considered in determining the most accurate answer.  [b]Half of a pot can be completed and should be included[/b].  [/quote]

This must be some strange new definition of the term "completed".

If I come to your place of business and give you 5 pots to glaze, please....   and you only have enough glaze to cover 4.5 pots.... have you completed 4 pots?   Or 4.5 pots?

If I come up to pick up my pots I will only be paying for the 4 completed pots.  I will not be paying you half for the half job you did on the 5th pot.  That pot was not completed.

It was glazed.  If the question were "how many pots can have glaze on them" then I can see an answer of 4.5.   But the term "completed" means something in the English language.   I don't think this is a Common Core issue.   In fact many math problems ask exactly this type of "real world" question, for example:

Jen has 38 oranges.   She needs to fill trays completely with the oranges in order to put them up for sale.   Each tray will hold 6 oranges.   How many trays can she sell?

The answer is 6 trays, not 6 and 1/3 trays.[/quote]
