Blog #1 - Due Friday, December 18, 2009
Choose one of the following problems to solve and write an explanation for. This assignment is due no later than Friday, December 18th!
Problem 1
You count from 1 to 100 and you clap while saying the multiples of the number 3 and the numbers that are not the multiples of three but have 3 as the last digit. How many times will you clap your hands?
Problem 2
A doorman works according the following schedule: he works for 4 consecutive days and has the fifth day off. Last Sunday he had the day off, and on Monday he started work according to his schedule. After how many days, including that Monday, will he have a day off on Sunday again?
Assignment - In your comment remember to include the following:
Your name (first name and last initial)
Your class
The answer to the problem you solved.
An explanation that includes the strategy you used to solve.
Is there another way to solve this problem?
Would you be willing to use the same strategy if the numbers were much larger?
Any additional thoughts you have about the problem(s)
Remember when you "publish the comment" it will not appear on the blog until Mrs. DaSilva has a chance to read it and approve it.

Express Yourself in Words!!!
Often times in math, once you've solved the problem and have an answer, you move on without giving an explanation as to why your answer makes sense. Sometimes we get too caught up in just the numerical answer that we are looking for.
It's not very easy to show your work on the computer screen. So, when you are assigned a problem on the blog you'll have to be able to communicate your answer in words. You should include the math language and skills that we've been learning and practicing in class recently. As always see if you can make connections to other situations where the same math could be used.
You will be scored on a 3, 2, 1, or 0 scale.
Example of what’s expected for these assignments:
Problem –
Field Trip – The 7th grade math classes are going on a field trip. The field trip will cost $7 per student. Write an expression to find the cost of the trip for s students. What is the total cost if 26 students go on the trip?
To earn a “3” on this problem, I would expect…
Let s = number of students on trip.
Let 7s = total cost in dollars of trip.
7s; s=26
7*26 = $182
The total cost of 26 students to go on the trip would be $182.
I started with the variable that was given to build the expression. Then I substituted in for the variable into my expression the number of students who were going on the trip. I then was able to solve the expression to find the total cost.
To earn a “2” on this problem, I would expect…
Let s = number of students on trip.
Let 7s = total cost in dollars of trip.
7*26 = $182
The total cost of 26 students to go on the trip would be $182.
I wrote the expression and then substituted in for the variable the number of students who were going on the trip and got my answer.
To earn a “1” on this problem, I would expect…
Let 7s = total cost in dollars of trip.
7*26 = $182
The total cost of 26 students to go on the trip would be $182.
To earn a “0” you have not completed the assignment.
