Once upon a time Mathematics was easy to teach. A typical lesson would begin with a direction towards a particular page of the text book and would conclude with the ceremonial marking of the answers. This process was repeated over and over, year after year and in the end students would be able to repeat the required method with a satisfactory degree of accuracy.
Watching video from the Apollo space programme one can't help but notice how things have changed since those days in the early 1970s. Banks of small round rectangular screens, dot matrix printers, a myriad of switches and dials each with a specific task to perform and a design aesthetic that says functionality in mild mannered green. What is missing beside the sort of computing power we carry in our pockets today are women. In the 70s science and engineering was what men did and from a quick look at the statistics there continues to be much room for change.
According to the National Center for Education Statistics in 2003, geometry was one area of weakness among American students.
Origami has been found to strengthen an understanding of geometric concepts, formulas, and labels, making them come alive.
Thinking Skills
Origami excites other modalities of learning. It has been shown to improve spatial visualization skills using hands-on learning.
Fractions
Folding paper can demonstrate the fractions in a tactile way.
Problem Solving
Often in assignments, there is one set answer and one way to get there. Origami provides children an opportunity to solve something that isn't prescribed and gives them a chance to make friends with failure (i.e. trial and error).
Origami is a fun way to explain physics concepts. A thin piece of paper is not very strong, but if you fold it like an accordion it will be.
Researchers have found that students who use origami in math perform better.
STEAM
While schools are still catching up to the idea of origami as a STEAM engine (the merging of these disciplines), origami is already being used to solve tough problems in technology.
Additionally, the National Science Foundation, one of the government's largest funding agencies, has supported a few programs that link engineers with artists to use origami in designs. The ideas range from medical forceps to foldable plastic solar panels.
Origami, the ancient art of paper folding, has applications in the modern-day classroom for teaching geometry, thinking skills, fractions, problem solving, and fun science.
"This is a list that comprises some of the best math apps and extensions in Chrome store. We have literally gone through hundreds of apps to finally decide on the apps that would make the cut.These extensions are meant to help kids develop math skills through a wide variety of exercises, activities, games, interactive simulations and many more. Some of these apps are integrated with Google Drive and are also available for iPad, Android, and Chromebooks."
"Progressions Documents", the documents which outline specific mathematical learning progressions upon which the Common Core State Standards were based. If you're in a state that teaches these you should definitely find some time to read through them. If you are a teacher elsewhere, it can't hurt to understand these progressions.
