Week #1

Week #1 

Done and boy am I whipped!

 

This is an activity that I found on Eberopolis' blog--the kids loved working on it and I think it took a lot of perseverance for the beginning of the year when brains are still a little mushy.

 

I had to front-load the students with 4! (4 x 3 x 2 x 1 = 24) and we had to discuss the square root of 4, but after that they were off and running.  It was a good opportunity for me to walk around and see who was contributing to the conversation and who was struggling with basic equations.

Rules:

Using some arithmetic combination of four 4's, can you write an equation for each of the numbers from 1-100? Here are the rules:

• You may use any combination of addition, subtraction, multiplication, and/or division
• You may combine numbers, e.g., use 2 of the fours to make the number 44
• You may insert decimal points
• You may use a four as an exponent
• You may use square roots
• You may use factorials, e.g., 4! is equivalent to 4 x 3 x 2 x 1 = 24
• You may use overbars to make a decimal repeat
• You may NOT use any digit other than a four
• You MUST use all four 4's in each solution
