Math anxiety is contagious Nervous female teachers may hurt girls achievement… Math Gāmz are the solution!
BY TRACY CLARK-FLORY
In third grade, my class would play a game where we took turns reciting multiplication tables. If no one messed up, we were promised the grand prize of a trip to the donut shop. The pressure, the prospect of depriving my entire class of deep-friend sweets, made me so nervous I once threw up in the middle of math class.

Question: Whats an independent variable?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isnt changed by the other variables you are trying to measure. For example, someones age might be an independent variable. Other factors such as what they eat, how much they go to school, how much television they watch arent going to change a persons age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables.
Question: Whats a dependent variable?
Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.
Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in the way that makes the most sense. Then you can figure out which is the independent variable and which is the dependent variable:
Independent variable causes a change in Dependent Variable and it isnt possible that Dependent Variable could cause a change in Independent Variable.
For example:
Time Spent Studying causes a change in Test Score and it isnt possible that Test Score could cause a change in Time Spent Studying.
via What are Independent and Dependent Variables?-NCES Kids Zone.
Breaking this down further, we summarize independent and dependent variables in this way:
- Independent Variables are changes that occur in an experiment that are directly caused by the experimenter (you!)
- Dependent Variables are changes that occur due to independent variables.
- A Controlled Variable is anything else that could influence the dependent variables (you must work to prevent these other variables from influencing the results… by controlling them).
via Independent and Dependent Variables.
Controlled variables must be carefully monitored and kept equal in your experiments – otherwise they could mess up your experiment by making your results false or unreliable.
They are used to distinguish between two types of quantities being considered, separating them into those available at the start of a process and those being created by it, where the latter dependent variables are dependent on the former independent variables.

Obama should launch his own moon shot. What the country needs most now is not more government stimulus, but more stimulation. We need to get millions of American kids, not just the geniuses, excited about innovation and entrepreneurship again. We need to make 2010 what Obama should have made 2009: the year of innovation, the year of making our pie bigger, the year of “Start-Up America.”Obama should make the centerpiece of his presidency mobilizing a million new start-up companies that won’t just give us temporary highway jobs, but lasting good jobs that keep America on the cutting edge. The best way to counter the Tea Party movement, which is all about stopping things, is with an Innovation Movement, which is all about starting things. Without inventing more new products and services that make people more productive, healthier or entertained — that we can sell around the world — we’ll never be able to afford the health care our people need, let alone pay off our debts.

Teach Roamer to Hit the Bull’s Eye!
Kimiko and Sage, age six, learn about DISTANCE and DIRECTION by playing robot darts.
After each attempt they mark their Roamer robot’s place and correct their program (or their aim). On the 3rd try their robot puts a mark in the bull’s eye!
Solution: CM CM ^8 steps GO!
Key: CM = Clear Memory; ^ = Forward; 8 = Number of Roamer Steps; Go = Execute!
