Make a Million Dollars
Here is the link to my Make a Million Dollars Spreadsheet!
If I started saving money now, how long would it take me to be a millionaire?
I found that when you invest $1000 dollars at a 3% rate of change it takes 234 years, when you invest $1000 dollars at a 4% rate of change it takes 154 years and when you invest $1000 dollars at a 5% rate of change it takes 142 years.
I also found that when you invest $10000 dollars at a 3% rate of change it takes 156 years, when you invest $10000 dollars at a 4% rate of change it takes 118 years and when you invest $10000 dollars at a 5% rate of change it takes 95 years.
Finally, I found that if you invest $100000 dollars at a 3% rate of change it takes 78 years, when you invest $100000 dollars at a 4% rate of change it takes 59 years, and when you invest $100000 dollars at a 5% rate of change it takes 48 years!

Scattered Data Forms.
Here is the link to my original form
here is the link to my google spreadsheet. Earlier, I sent a form to my math class asking two questions. What family will you see for Christmas and how many letters are in your middle name. The spreadsheet has my data and a scatterplot on it. The two questions have absolutely no correlation.

Let's go Shopping
I created a google spreadsheet with the prices of a tabet computer, a 4th generation Ipod touch, computer case, Ipod case, Flip camera, and a Digital camera. The budget was $1,500 dollars and i used $1,055.63 dollars. The websites where you can find these idems are hyperlinked from the spreadsheet. You can access the spreadsheet here.
1st Trimester Reflections
1. What is one thing that you are proud of so far this year in math?
My grade and the effort that I put in to my homework and test to get that grade.
2. What is one thing you wished you had done better on?
Getting my homework notebook signed.
3. Has Algebra been a challenge for you so far this year? If yes, please list some topics that challenged you.
Algebra has been a challenge in the fact that i am learning new things. No topic has really challenged me besides mixture problems when i was first learning them.
4. List the topics in Algebra that you feel that you have mastered so far this year.
Multi-step equations, mixtures, dilations (and the other stuff on the graphs - transformation, reflection ect.), mappings, and representing an equation on a graph.
5. Pick two goals for the 2nd trimester. Then tell how you will accomplish these two goals.
I hope to get better original grades on my homework so that I can learn to be less dependent on corrections. I will accomplish this goal by spending more time on my homework. My 2nd goal is to be able to use math counts i my math homewok and regular class time. I will do this by working hard in math counts and learning all that i can to help me for later on.
