Natural number

Ten fingers. What can we count on ten fingers? Most of you could count how many siblings you have, how many days until winter break, or how much money you have in your backpack. For me, I can count how many schools I've been to so far in my life, 8. It may not seem like a lot but consider they are towns, cities, and even countries apart.People say it's easier for me since I was "little" and I won't remember the friends I've made or worry about customs I had to change from moving to a different…

Dunbar’s number. Dunbar’s number is, in fact, a series of numbers that represent the number of friends a typical person has that fit varying categories of familiarity and closeness. Maria Konnikova writes about Robin Dunbar’s research in her essay “The Limits of Friendship.” Robin Marantz Henig discusses the current plight of American millennials trying and failing to adjust to the world fast enough and become adults in “What is it About 20-Somethings?” Social media allows one to expand the…

of all numbers: The dictionary meaning of prime is ‘Of first importance’ or ‘Of the best quality, excellent’ etc. What is so great about prime numbers? A number is said to be a prime if it is divisible only by 1 and itself. 5, for example, is a prime number because it is divisible only by 1 and 5. The number 4 can be divided by 1, 4 AND 2. So it is not a prime number. Numbers that are not primes are said to be composite numbers. The fundamental theorem of Arithmetic states that all numbers are…

Introduction Mathematics is a necessary aspect of my life. In my home, work, school and even social environments, numbers surround me. Over many years, I have learned how to derive meaning from them or use them to help me figure things out. During this unit, I have learnt, re-learnt and applied various areas of mathematics to help me achieve the outcomes and find solutions to each ‘Thinking Time Problem’ [TTP] presented. These relate to the Australian Curriculum- Mathematics proficiency strands…

Some ordered because they thought it would be fun to have their favorite numbers and letters on the number plates made specifically for them, when custom number plates were first introduced to the members of the general public. Of course, it is a fact that it's usually abundant and famous people with tailored plates hooked up on his or her high class cars. However, it soon turned out to become a very popular trend that not only famous individuals order custom plates from licensed plate makers.…

have to solve a problem to get the numbers out. The problem is 4(5+2x)-5=3(3x+7). First our mathematicians figured out 4 times 5 and 2x also 3 times 3x and 7 and reduced it to 20+8x-5=9x+21 then they subtracted 20-5 which reduced the problem to 8x+15=9x+21 then they subtracted 8x with 8x and 8x with 9x and written down its 15 =x+21 and then finally they -21 with 21 and 21 with 15 and got -6=x There is still no word on if the robbers are going to release the numbers but we will let you know as…

structures according to certain rules . Originally these elements would put be interpreted as numbers or quantities, so that the algebra somewhat originally was a generalization . The adjective " algebraic " usually denotes a relationship with algebra , such as in algebraic structure . For historical reasons, it may also indicate a relationship with the solutions of polynomial equations , algebraic numbers , algebraic extension or algebraic expression. It AGREES distinguishes between :…

I have found that number talks are really helpful for building number sense as well as assessing number sense. When I use number talks in my classroom it allowed me to easily see gaps in understanding with some of my students. Simply learning math facts through memorization is not very helpful. I can't count the number of times that I have memorized facts of some sort for a test and then promptly forgotten all of the facts after finishing the test. Our brain just doesn't work that way. If we…

Numbers are everywhere connected to everything we do. We use them to measure years, months, weeks, days, hours, and seconds. We count them in dollars and cents. We measure in feet, inches, meters and yards. The food we eat has a caloric number attached to it. We regard success and failure and distinguish ourselves according to the number of each. We age by ever mounting time. We calculate and distribute. We find comfort in the fact that 2 + 2 will always equal 4. Numbers have definite effect on…

During my time in my Kindergarten LAL/Math resource classroom I observed a student, who will be referred to as Ally for confidentiality reasons. Specifically, I observed Ally’s number recognition ability. Ally is currently five years old and is in her seventh month of Kindergarten. Ally lives at home with her mother, father, and older brother Mathew. Ally’s parents are very involved in her school life. They attend celebrations, meetings, and other events. Ally comes from a Russian family. Her…
