Triangular Numbers Eli Nazarian Ms. Ramson H Algebra 2A October 21, 2014 A triangular number is a number that counts the amount of objects that form when they are put together to form an equilateral triangle (a triangle with all equal sides). The most common object used to form a triangle are dots. When the dots create an equilateral triangle, the number of dots seen in the triangle represent the triangular number. Overall, the sequence is generated from a pattern of dots which form a triangle

Fractions can also be used to represent ratios or even division equations and all rational numbers. While fractions come in many different forms such as mixed numbers, improper, vulgar and proper fractions, the function of a fraction is generally the same—to represent parts of a whole. To simplify the matter further—if you can solve a division problem, then you are able to use

The Codification uses a hierarchy to organize its subject matter. Area is the largest collection, and then comes topic, subtopic and section. Each topic, subtopic and section is identified with a number and a title. The numbers provide a simple way to find specific accounting guidance. A three-digit number and a title identify topics. The first digit of the numerical identifier resembles the area of the topic. Subtopics are either exclusive or shared. Exclusive subtopics have unique content and shared

granted using calculator for the past decade. There are downsides to relying more on the calculator than relying on “old-fashioned” mind. “Patterns as Aids” becomes a problem when a student follows rules without understanding and calculates large numbers mentally using tricks but fails to understand the purpose of the processes or steps. Therefore it is better to understand less but thoroughly, than to be an expert in memorizing tricks and rules without any understanding. Principles must be taken

Identify his strengths and error pattern. Describe why you think that way. • He is excellent in his addition skills. He understands how to add numbers together, but he is just confused about this set up of addition. His error pattern is that if he has a two digit number in the first column he will put both numbers in the answer instead of the number in the ones place. For example, in the first problem he adds 6 + 7 correctly (13) but he puts both the ones and the tens in the answer. Then he brings

Apparatus This experiment used an instruction sheet which indicated the relevant instructions for each condition. (This is included in Appendix 1). The experiment also used an identical clock for all the conditions with roman numerals depicting the numbers, where four was shown as IIII. (This is included in Appendix 2). The rest of the apparatus included paper, pens and a stop watch. Procedure In this experiment the participants were split up into three conditions. The

Francis Galton was born into a wealthy quaker family, their fortune coming from his banker father. Of course, his mother wasn 't a nobody; she was the daughter of the Erasmus Darwin, a man of many things, one of which was medicine. At an early age, Francis was expected to become a doctor by his father, which didn 't leave him with much of a choice, since his father could cut him off at any time. So he went to Trinity and studied medicine and mathematics, until he had a nervous breakdown from the

of the Number 3 in Fairy Tales Numbers do not exist. They are creations of the mind, existing only in the realm of understanding. No one has ever touched a number, nor would it be possible to do so. You may sketch a symbol on a paper that represents a number, but that symbol is not the number itself. A number is just understood. Nevertheless, numbers hold symbolic meaning. Have you ever asked yourself serious questions about the significance, implications, and roles of numbers? For example

The fraction lesson that we worked on in class has given me a deeper understanding of fractions that I did not have before. Fractions have never been a topic of math that I have took a liking to. They have intimidated me for as long as I can remember. I did not imagine in my wildest dreams that there was going to come a day that I could understand fractions. Being enrolled in the math for educators course has contributed significally to this newfound understanding. This class has taught me a lot

in 400 AD. This was first used as legal matters such as commerce, education, literature, and science. This type of math was mostly used by Egyptians, but there numbering was different than ours today. Instead of them using numbers they would use pictures to illustrate the numbers. It is said that hieroglyphics were created by the Egyptian god Thoth. He is said to be the god of the moon, magic, and writing. Hieroglyph comes from the root word hieros which is Greek meaning sacred, and the root word
