Make a Million Dollars

here is my spreadsheet
I saw that when you increase your money and interest rate, it takes fewer years to earn a million dollars.
$1000 with interest of 3%, 4%, 5%: 234, 177, 142
$10000 with interest of 3%, 4%, 5%: 156, 118, 95
$100000 with interest of 3%, 4%, 5%: 78, 59, 48

My Math Casts

math cast uno
math cast two
math cast three
To make a math cast you have to pick a problem and fist practice solving the problem. Next you make a twitter account because screenr uses the username. Then you go to screenr and click on record. After you do that, you open painter to write with and then you click on the green record button and start solving your problem by writing with the tablet and talking in to the microphone/headset.
I liked the math casts because they were fun to make and you had to actually understand the problem to make a math cast. I don't think they were useful for other students to go back and watch them but I think it was useful for  me to learn how to solve the problems.
