Hate Math? These Mental Tricks Will Have You Multiplying Faster Than Einstein Ever Could! Hate Math? These Mental Tricks Will Have You Multiplying Faster Than Einstein Ever Could!

The Geometry and Mathematics of these lenses is very involved, and they cannot be simply mass produced and tested by computer robots. Lots of effort required to manufacture these lenses results in their very high price tags. Here is a diagram showing how the zoom lens internal arrangement changes as we zoom from 18mmm wide angle to 200mm fully zoomed in: Image Source:
#TMC14 GWWG: Talking Points Activity – cultivating exploratory talk through a growth mindset activity This activity is the one I am most excited about bringing to #TMC14 and to the Group Work Working Group.

Difference Between a Percentage and a Rate (as explained by medical field) Often we hear the question, "What is the difference between a percentage and a rate?" They are both calculated using a numerator and a denominator. However, the relationship between the numerator and denominator makes the difference. Percentages Indicators which use percentage are the most commonly used indicator type in healthcare. Mathematical Mindset Teaching Guide, Teaching Video and Additional Resources We have designed a Mathematical Mindset Guide to help teachers create or strengthen a growth mindset culture. This guide contains five Mathematical Mindset Practices along with links to teaching videos. The videos all show Jo and Cathy teaching middle school students. There are different stages described in each practice to help capture the journey of a mathematical mindset classroom and the evidence teachers may collect along the way for their own reflection or for discussion with colleagues. The guide has been designed for teachers to use in the process of self-reflection, or for coaches or administrators to use to encourage a mindset teaching culture.
