In many cases, they memorize the rules without fully understanding them, and they sometimes even manage to squeak by a course. Why waste their time on these archaic entities; they are never going to see them again. Maths Maps I am excited to introduce you to my new project idea that I hope will result in some engaging content for our classes. It is collaborative in the same way the Interesting Ways resources are and I will need your help to make it a success. Elevator Pitch

Solving Exponential Equations by Using Logarithms {*style:<i><b>Solving Exponential Equations: Most exponential equations do not solve neatly; in solving these more-complicated equations, you will need to use logarithms. For instance: If this equation had asked me to "Solve 2 = 32 ", it would have been easy, because I could have converted the 32 to 2 5 , set the exponents equal, and solved for " = 5 ". But 30 is not a power of 2 , so I can't set powers equal to each other. I need some other method of getting at the , because I can't solve with the equation with the variable floating up there above the 2 ; I need it back down on the ground where it belongs.

One of the big things we talked about however was privacy and keeping all personal information and images off of their blogs. So I had them create an Avatar to represent them online. At first my students seemed genuinely bothered by the fact that they could not place their own pictures on their blog but after some conversation about safety and the purpose of the blog most agreed that using an Avatar would be just fine. The following list seemed to be the most popular avatar creators among my students.

Plants 'do maths' to control overnight food supplies Plants have a built-in capacity to do maths, which helps them regulate food reserves at night, research suggests. UK scientists say they were "amazed" to find an example of such a sophisticated arithmetic calculation in biology. Mathematical models show that the amount of starch consumed overnight is calculated by division in a process involving leaf chemicals, a John Innes Centre team reports in e-Life journal. Birds may use similar methods to preserve fat levels during migration. The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. 'Astonished'
