For students tied to their calculators or computers, I can demonstrate three methods of multiplying two digit numbers in their heads.
I can relate estimation methods that engineers and scientists use in the work place to determine that their calculations are reasonable. Related to the final result is the initial "guesstimate" an engineer or scientist might make before starting calculations.
I can show what results one gets if one uses a base system other than our base system of 10. Modern computer systems rely heavily on a base system of 2.
My formal education consists of a bachelor's degree in chemistry (more than 160 hours) from Case Institute of Technology and graduate courses in chemical engineering from Lamar State University. I am certified (by TEA) in math, chemistry, and physics. For 13 years, I have been substituting in the Irving, TX, school district. I also substitute in the HEB (TX) school district.
This knowledge of mathematics is tied in with a life time of industrial and research activity in lubricants and polymers (polyethylene). Through me the student can learn that proficiency in mathematics leads to the ability to navigate the life stream of the world of work. In other words, academic success can mean financial rewards.
I can demonstrate how word problems convert words of a sentence into mathematical symbols.
