The Problem Of Mental Multiplication

Benchmarking numbers 5 and 10 focuses on middle numbers and breaking apart numbers to get the

When you are multiplying fractions you multiply the numbers on top as well as the numbers on the bottom. For example:

We can use this information for simple division, multiplication and even when multiplying and dividing larger numbers. This information can be used when cooking, grocery shopping, building things etc..

In an Op-Ed by Andrew Hacker “Is Algebra Necessary,” he explains why math is a difficult over glorified subject, that must be removed from high schools and universities. However, Through the power of education, the language of numbers helps us make important decision and preform everyday tasks (learner.org). Math, for many is a challenging subject, but as technology advances, classrooms tailor lessons for students who prefer to engage hands on. Therefore, numbers, symbols and letters are not only for the classroom, but also the real world. I believe math is an important subject, removing it from high schools and universities is not the answer, instead it is necessary to implement technology because math will always be used.

Include expressions that arise from formulas used in real world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).

Even if you do the Math equation the same, the symbols can cause the answer to shift, and make it so the two aren’t the same.

of the technology U.S. teachers take for granted, and therefore especially in math and science

These are the two basic steps for rounding decimals to a place value to the right of the decimal point

Have you ever wondered what are the correct steps to take when adding and subtracting decimals?

In order to precisely evaluate an expression involving the division of decimals, there are certain steps to ensure success:

Completing algebra problems can be difficult if you don’t understand the properties of real numbers. There are several properties in algebra dealing with both integers and real numbers; one that will be the focus of this report will be the distributive property. We use this property when we are combining addition and multiplication in an algebraic expression. Let’s say that you are presented with the expression 6x(2 + y) = 9x + 5xy, now with this problem the order of operation would have you to add the terms in parenthesis first, by using the distributive property it allows to simplify the problem by multiplying all

For example, if this rule did not exist, you would have gotten a lot of questions incorrect on a wide variety of things; homework, quizzes, tests, standardized tests, and classwork. This rule is important to me because math is one of my favorite subjects, and it would be a bummer if I am getting most of a common type of math problem wrong. Without this rule, math would not have made this much sense. To clarify, with the order of operation, you would know why you do some operations

Multiplicative thinking, fractions and decimals are important aspects of mathematics required for a deep conceptual understanding. The following portfolio will discuss the key ideas of each and the strategies to enable positive teaching. It will highlight certain difficulties and misconceptions that children face and discuss resources and activities to help alleviate these. It will also acknowledge the connections between the areas of mathematics and discuss the need for succinct teaching instead of an isolated approach.

Symbolic representation using base-ten and expanded algorithms is a way to show students the written connection to the visual models used. The partial-products algorithm is a more detailed step-by-step process and therefore more advisable to avoid errors in students learning to grasp the procedure (Reys ch.11.4). This process allows students to visualise the distributive property more easily. However, the standard multiplication algorithm is quicker and acceptable for students, if the teacher feels they have complete understanding of the steps in the partial-products algorithm.

Technology has made great strides in the past 20 years. It plays a very important role in our lives today and even plays a critical role in the way students learn all over the world. Unfortunately, students now rely on technology instead of learning key fundamentals. Technology has replaced the need to learn and most answers are just a google search away. Technology has also become expensive and lower socioeconomic school districts have found affording the newest technology difficult because of their lack of funding. Technology is a great learning tool when used appropriately. The lower socioeconomic school falls behind in the expanding frontier of technology in the classroom because they cannot afford it compared to their counterparts and results in a gap in education. The development of technology in the classroom has caused students to fail the learning of fundamentals and has exploited lower socioeconomic school districts.
