Number Relationships #1

Today, we began our investigations into "Numbers and Operations." The first task was the following prompt:

                        Question: How is each number below different from each of the others?

                                81  81  36  14

Check MTN for work, discussion and results. All were in agreement that the first three numbers have "9" as a factor. The number "14" is the "odd man/number" out in this series.

HOMEWORK: Due on Monday, 9/22:  Write two sets with 4 numbers in each set to compare as in the above problem. Use different numbers. Investigate with different symbols such as square root, powers of 2 or 3, fractions, percents, or decimals, etc. This will be a PRACTICE Grade.

The Betula Group was able to move on to the following prompt:

                 Question: The students in Mr. Mila’s class want to know how old he is. Mr. Mila told them, “My age can be written as the sum of consecutive odd numbers starting from one.” How old might Mr. Mila be?

We did not have time to complete, but will do so on Monday.

Our two day trip is tomorrow and Friday.  The next BLOG entry will be on Mon., 9/22. Have a great weekend.
