Making Geometry Fun with Origami
Lucila Cardenas Vega
University of Texas at Brownsville
Introduction
Teachers must have an understanding of students’ mathematical thinking in order to create meaningful learning opportunities. This becomes more relevant when teaching subjects that not all students have an interest for, such as, geometry. Since geometry is the study of shapes and configurations, it is important to understand how a student thinks about the different properties in geometry including, symmetry, congruence, lines and angles.
Students remember a lesson better and the information becomes more significant when learning is accessed through hands on activities. (Pearl, 2008). Origami is the art of transforming a flat sheet of material into a finished sculpture through folding and sculpting techniques. The use of origami can be thought of as art; however, there are so many other benefits of incorporating origami in geometry lessons.
According to experts, origami teaches students how to follow directions, encourages cooperation among students, improves motor skills and it helps develop multi-cultural awareness (Weirhem, 2005). Origami activities used in geometry lessons reinforces vocabulary words, facilitates the identification of shapes and simplifies congruency and symmetry (Pearl, 2008). In origami, students take a flat piece of paper and create a figure that is three dimensional. The use of origami in geometry is not new. Friedrich Froebel, the founder of kindergarten, was the first to introduce Origami into formal education. (Tietze, 2008). Froebel recognized the value of children learning through enjoyment and discovery. He considered the use of paper as a means for children to discover for themselves the principles of math and geometry. (Tietze, 2008). Piaget, the well known child development psychologist, argues that motor activity through precise movement is important to the cognitive development of the brain (Pearl, 2008).
This case study, aside from looking into the way students think when trying to identify congruency, symmetry and shapes, is also intended to discover the benefits of the use of origami to help students realize their imagination while exploring important mathematical concepts. This study seeks to identify the benefits of using an innovative teaching tool, such as origami, in order to improve the scored of children who struggle with geometric concepts.
Method
In this study, I examined the benefits of using origami to teach geometry concepts to elementary students who have difficulty understanding geometric concepts. The purpose was to try to improve their interest in certain concepts by using an inventive instrument such as origami designs.
Participants
The participants were randomly selected at an elementary school in Port Isabel, Texas. They consisted of two boys and two girls. They are in the fourth grade and struggle with geometry concepts. They are of low socio-economic status.
Materials
The materials used in this case study were step by step instructions to specific origami designs, origami paper, scissors, pencils and vocabulary flash cards. The students were provided with paper pre-cut to the appropriate size for each origami design. A copy of the directions for the chosen origami designs for each student was provided. The classroom environment was set up so that the participants could work in a table space large enough for the individual space needed.
Procedure
First they were given a brief history on what origami is and where is originates from. Next, the participants were shown example of previously designed origami sculptures. The lesson was set-up by orally reviewing key geometry terms for example, symmetry, congruent, faces, edges, triangle, square, rhombus and rectangle. The origami paper was distributed and students were asked to work in pairs while the instructor guided them through their first origami design. The first design was a simple sculpture was of a boat. Students were taken step by step of each folding instruction. Instructor spoke slowly and emphasized vocabulary terms previously reviewed.
Instructor: Begin with a rectangular piece of paper. Fold in half as shown. Then partially fold it again, making a crease near the top.
Student: Like this?
Instructor: Exactly.
Instructor monitored constantly to ensure that all students comprehended.
Instructor: Ok, now follow the crease and line up the corners and fold down.
Instructor: Now fold each edge of the paper upwards as I’m demonstrating. Use your fingers and you will notice e that it looks like a hat! What else do you notice of the shape so far?
Student: I see a triangle.
Student: I see two triangles and a rectangle.
Student: Both sides are the same.
Instructor: awesome! It has symmetry.
Instructor: very good, now we will continue a few more steps until we make a boat. Bring the corners of the hat towards each other. The edges will be pushed outwards. It's kind of like you're "squashing" the hat into a square.
Now take one lower corner of the square and fold it upwards. Flip the piece over and do the same for the other corner.
You now have a folded triangle. Open up the folded triangle, bring the corners together and again, press the triangle into a square as I am showing you. Now pull the outer corners of the square, one in each hand. Keep pulling to unfold your boat. We like to turn the boat over and expand the hole in the bottom. This will help it balance and float better.
Instructor: Ok, now let’s talk about or boats. What geometric shapes or terms did you notice during the process?
Students: I noticed triangles, rectangles, squares, and the boat has symmetry.
As an assessment, the participants were asked to create and origami sculpture individually by following step by step instruction that were given to them. This sculpture was scored using a rubric. Participants were asked to explain the sequence of folding the sculpture and use geometry terms learned.
Results
The participants were able to recognize and use basic geometric properties of two and three dimensional figures. The participants used appropriate vocabulary to describe the two-dimensional figure. The participants will be able to use this information in order to recognize and determine patterns and simple geometrical relationships. Overall, the participants enjoyed this activity. Some expressed that it did not seem like a geometry assignment but rather art class. All improved in listening and following directions skills.
Discussion
In some instances, the participants would appear anxious and frustrated if the sculpture would not look as planned. The instructor would re-direct them if needed. The students’ strengths were their enthusiasm in trying this new approach. They were very good at following instruction when they had visuals and step by step instructions that were given at their pace. They were able to incorporate their newly learned vocabulary terms rather easily and seemed to have made those words part of their vocabulary.
Their weaknesses were that they required the steps at a very slow pace and required constant reassurance during the process. After a few guided sculptures, the students were able to work individually and create successful sculptures. Before using the origami technique, I considered the students to be at a 0 or 1 in the van Hiele level based on their lack of understanding of the basic geometric terms and concepts compared to other students. After using the origami technique over a period of several months, the students have made significant progress and could be considered to be at a solid 1 or 2.
Conclusion
The case study involved using an innovative tool to analyze how students think about a geometric concept. The innovative tool used in this case study was the use of origami to help the learners make a connection of the geometric concepts. The participants were introduced to origami. The geometry terms were reinforced during the lesson to ensure they made a connection. During the process, the students were able to recognize several shapes that were being used in the steps to creating sculptures. I learned that the students were very engaged during the lesson and seemed to enjoy the activities. The lesson encouraged the students to work cooperatively and required both hands which activates the whole brain. I would recommend that others introduce geometry by using origami in order to make it fun and interesting. Geometry can seem boring and tedious to some students but by incorporating this entertaining technique students will be initially intrigued and want to learn more.

Math 157 Reflective Paper

...Math 157 is to assist the learner with understanding day to day applications of Mathematics. This course can also be extended to students who find it challenging to grasp the basics of Mathematics. The curriculum for Math 157 consists of data analysis, application of geometry, application of measurements and last but not least, introduction to probability. To be more precise, the topic application of geometry involves solving problems related applications of two and three dimensional shapes. As an upcoming teacher, I believe that geometry can be found everywhere. To teach about two and three dimensional shapes in the classroom will be interesting because all around us exist two and three dimensional shapes. The chapter on measurements includes identification and application of tools, different techniques and formulas in determining measurements; and introduction to probability pertains to use of suitable statistical methods in analyzing data. The concepts that I learned in this course are very relevant in to the characteristic of a professional teacher. The information that I learned in Math 157 will help me to teach my students math.

Some of the assessment approaches I plan to use in my math class are rubrics, drill and practice software. I intend to use Rubrics to tell me which particular area my student is falling behind. The drill and practice software which I will be using during mock tests will give me an instant feedback, thus saving my time that would otherwise be spent in manual grading. This way I can give more attention to my students. have chosen the top ten list for integrating technology in mathematics as the subject and the technology is Google sketchup and Geometer's sketchpad for teaching geometry.

Aircraft Design

...WHITE PAPER Design faster, better and more naturally with T-Splines >The complex challenges of aircraft design illustrate the revolutionary benefits of modeling with T-Splines. Introduction Schuyler ‘Sky’ Greenawalt is a designer and the owner of School Street Design Company, which specializes in custom and prototype tooling and production of composite structures for the homebuilt and experimental aircraft community. One of his recent projects was a conceptual model for a Formula 1 Reno Racer, a small competitive aircraft designed to compete in the Formula 1 class of air races at speeds of over 200 mph. Aircraft design poses unusual challenges for surface modelers, since the wings and tails need to be very accurate representations of airfoils, but the rest of the surfaces—fuselages and other secondary structures—need to be very smooth and fair. The blends between the two can be particularly difficult to edit and modify. The reason for the difficulty in modeling these surfaces is not the complexity of the design. Airfoil and fuselage profiles and shapes are well understood. Rather, the challenge comes from the inherent difficulty in creating complex shapes using traditional NURBS surfacing; specifically surfaces with varying level of detail, high accuracy requirements and complex blend transitions. Almost every surface and solid modeling application on the market today is based on a technology called non-uniform rational BSplines (NURBS). Not until the availability of T-Splines...

Leonardo Da Vinci

...The Renaissance was the period of time when artists put significance on learning and understanding the natural world before drawing a picture or creating a sculpture. A painter wasn’t strictly a painter any longer; he was also a writer, mathematician and musician. A lot of time was devoted to observation and people watching, as trying to understand the world and society on deeper levels. Mathematical knowledge was used for creating more realistic pictures then previously. Researching the relationship between geometry and proportions was necessary the integration of science and art in order to construct buildings and sculptures. One of the greatest artists, scientists and researchers at that time was Leonardo Da Vinci, who was convinced that "a man - is the model of the world". He was the first artist to open a human body and create images of its organs. Artists of the Renaissance were more open to experimenting with new drawing techniques and themes than their Medieval counterparts. One of his most remarkable scientific works is a diagram of a human body in a circle and a square. The drawing was part of Leonardo’s personal notes and was unknown to exist until three hundred years after his death. The diagram was never officially titled, but because of its nature it received names such as: “Vitruvius man”, “Proportional study of a man” and “Man of proportions”. Leonardo’s drawing of Vitruvian man is beyond anything that was done preciously by any other scientist or artist not...

...Running head: Adolescent Literature in the Content Area Classroom Adolescent Literature in the Content Area Classroom Kimberly O’Brien Grand Canyon University SED 523N Adolescent Literacy August 3, 2010 Abstract Knowing how to increase student’s literacy skills in math, science and social studies is to teach student’s meaning of the words, historical information, and formulas the teacher instructs the student to learn. If all of the students are to figure out math equations whether in a story or numeric form, the student needs to read for the meaning, and just not the words or numbers. Adolescent Literature in the Content Area Classroom Teachers should always question themselves regarding the student’s ability to comprehend, complete the task, and whether the student’s are retaining the vocabulary instruction objectives.

Klein’s photographic style is ‘in your face’ and close up often having a theatrical look with many being harshly framed or blurred. His images are grainy and satirical often exploring the more abstract parts of a location like in New York where he shot images showed ‘The big apple’ as a kind of slum. Many American publishers were against this and didn’t believe it showing New York in a good way. His passion for exploring the unexpected can evidently be unappealing but his documentation of New York is considered one of the most revolutionary publications of street photography making him a pioneer of 20th century photography and an inspiration for many modern day photographers.

Physics 1

...Galileo Galilei Introduction It is no question that Galileo was an influential scientist in his time and still is today (picture located on page 6 from google.com). Though his most notable discoveries were in the field of astronomy, we cannot label him simply as an astronomer. He authored many important works including, Sidereal Messenger (also known as Starry Messenger), but unfortunately, due to the power of the Catholic church in his native Italy, his work in astronomy was widely rejected by his countrymen. His contributions to physics also place him in the ranks of the greatest scientists of all time. Without Galileo’s contributions to astronomy, mathematics, and physics, we would lack many basic understandings of the universe and our world. Body Galileo Galilei was the son of a musician born in Pisa, Italy in 1564. He studied medicine, but his interests laid in mathematics and physics. At age twenty-five, he became a professor of mathematics at Pisa. In 1591, he moved to Padua and lived there for many years. During his time in Padua, he had a twelve-year long relationship with a Venetian woman named Marina Gamba. The couple never married, but they had three children, two daughters and one son. Later, he moved to Florence where he lived for the remainder of his life. He died in 1642, coincidentally, the year of Sir Isaac Newton’s birth (“Galileo, Galilei (1564 - 1642)”). Galileo’s discoveries contributing to the fields of astronomy are what he is most famous for though...
