1/26/18- We started Math Challenge this week. We are working on the strategy of

*Using a Table/Chart.*2/6/18- The students have been working on the strategy

What is the greatest amount of money you could leave for a tip if....

-No paper money is left

-With the coins that are left, change cannot be made for a quarter of for a dollar

Mr. Baker has 22 vehicles. Some are bicycles and some are cars. These vehicles have a total of 68 wheels. How many bicycles and how many cars are there?

2/15/18- This week we are working on a new strategy

Twelve talkative teenagers decided to create their own telephone system. Telephone lines were set up so that every person could call each of the other 11. How many lines are needed altogether?

How many blocks would be needed to make a staircase like the one shown 10 steps high?

*Using a Table or chart*. They are doing a good job problem solving with their partners. Here is an example of the problems:What is the greatest amount of money you could leave for a tip if....

2/15/18- This week we are working on a new strategy

*Look for a Pattern*. When we are using this strategy we are looking at how a pattern may help us solve the problem. Here are some sample problems:Twelve talkative teenagers decided to create their own telephone system. Telephone lines were set up so that every person could call each of the other 11. How many lines are needed altogether?

How many blocks would be needed to make a staircase like the one shown 10 steps high?

3/9/18- We are finishing up Math Challenge with the strategy of

Example:

A lady has a certain number of dollar bills in her purse. She has no other money. She spends half the money on a hat and gives $1 to a beggar outside the store. She spends half the remaining dollars for lunch and tips the waiter $2. She then spends half the remaining dollars for a book, and just before she goes home she spends $3 on a hot fudge sundae. She now has $1 left. How many dollars did she begin with?

*Work Backwards*. When we use this strategy, we start by using what we know at the end and work our way backwards.Example:

A lady has a certain number of dollar bills in her purse. She has no other money. She spends half the money on a hat and gives $1 to a beggar outside the store. She spends half the remaining dollars for lunch and tips the waiter $2. She then spends half the remaining dollars for a book, and just before she goes home she spends $3 on a hot fudge sundae.

4/5/18- Math Challenge has ended for the year.
