1. One of the key things that I learned from Developing Whole-Number Place-Value Concepts is that place value is an important concept for students to learn. This is so because students need to know the meaning of a number, especially when they are older. For example, when students are in 4th grade, they will need to know larger numbers, like 100,000. They will also need to know how to divide and multiple with larger numbers. So if students do not know the place value of these larger numbers, then

Math has changed quite a bit in past several decades, more so than stayed the same. Some things that have changed include math strategies, jobs, prices, and entertainment. For example, my grandma told me back in the day there were no calculators or other devices to help you solve difficult math problems. She said you had to do everything on paper and pencil while showing your work. When you were done, you would hand in your paper to the teacher. Here are some other ways math has changed from the

Problem 2) Sol: “By taking the reference of the example problem (page-223) in textbook (Algorithm Design - Jon Kleinberg and Eva Tardos ) we solve this problem.” We solve this problem in a similar way to the example problem in the text by using divide and conquer algorithm. Let a1,a2,…..,an be the sequence of n distinct numbers and returns N inversions and a sequence of numbers which are sorted in an increasing order a1’,a2’,a3’….an’ In this problem we sort the sequence first and then merging

Most soap box cars cost upwards of $300 but our soap box car cost half that at $150. Our soap car provides top of the line quality and performance for a low price. At SC inc we are committed to giving you the most fun, and reliability for the lowest price possible. To do that we went to many different stores and price compared. At SC inc we are able to do this by using cheap but reliable and good products. In my essay I will talk about using math in the real world and in our project and why people

I remember when I was younger, I used to have trouble adding and subtracting. It constantly confused me on where the "1" came from and why it's "carried". Something about it I just didn't understand and it frustrated me. I recall crying in the back seat of the car complaining to my mom about not having enough fingers to solve a complicated subtraction equation in a mathematics workbook my mother bought from family dollars. Then I would sometimes use my younger sister's fingers to cheat, in order

highlight different strategies. For example, it was helpful to me to see the adding-up strategy highlighted by a number line. I often use this strategy myself with subtraction (only because I took MA 316). I believe there is a great need in every elementary class for number talks. I took MA 316 and in doing so it was very eye opening. Growing up, I was taught math through standard algorithms. I was always amazed how other people just seemed to be good at computing numbers in their head. If I tried

Multiplicative thinking, fractions and decimals are extremely important areas of mathematics children are required to develop. The concepts within these three areas are related and it is critical for educators to support these relationships in the classroom. Multiplicative thinking involves recall of basic facts, the relationship between multiplication and division and underpins the development of fractions. Comprehension of fractions includes the division of objects, fractions as numbers, the multiple

rolling of the dice for fun. Base Ten Blocks has been the most used manipulative numerical system in just about every classroom all over the world. They help elementary students visualize the base ten system while working on basic or a more advance math lesson. One advantage of using Base Ten Blocks; when introduced early in elementary education it helps students learn to develop their counting skills at a quicker pace and provides a solid strong foundation for advanced mathematics. Another advantage
