Proportional Reasoning

The answer to last week's blog math question was that one football player's mass was 115 kg, so eleven of them would be 1 265 kg.  After reviewing the solutions I noticed that some students need to improve in the following areas:
-the question must be copied on the top of the page - the solution will mean nothing in the future without the question
-all steps of problem solving must be shown.  See the anchor charts for reference.
-we must show all steps and explain what we are doing..... since the mass of 115 kg was not in the question, you must show how you arrived at that amount
-the order of factors in multiplication sentences are still incorrect in some cases:  11 x 115 kg means eleven groups of one hundred fifteen kilograms which is correct BUT 115 kg x 11 means one hundred fifteen kilograms groups of eleven which does not make sense
-some students set up the division sentence incorrectly
-we DO NOT use commas in large numbers
-final statements must always be used

Here is the next question.  It is due Tuesday October 25 at 8:10 AM.  Please make sure the lined piece of paper has the question copied on it, the steps of problem solving are used, and your name is on it.
At Staples, 20 calculators are to be sold at a total price of $1000. How many would be sold if$\mathrm{\$}$1250 was spent?  Justify your thinking.
