In grade 9 Math and Coding become a more organic combination and meaningful connections can be made between the two. In this blogpost we will go over a number of concepts that could be discussed in class in order to demonstrate the connections between math and coding in a grade 9 math class. Variables in Math and Coding A variable is a value that is represented by a symbol and can change based on specifically defined conditions. In mathematics we see variables in algebraic expressions and algebraic equations; in proportions; in word problems that require us to assign variables to certain giv ..read more

After children learn the basics of counting and number recognition, their next step is to master skip counting. This new skill becomes the foundation for future math activities like multiplication and division; however, it also provides immediate benefits, like allowing children to count quickly and helping them to master addition and subtraction. These skills become important as children complete math drills and other activities. Skip counting is also essential to working with money and telling time. For these reasons, an understanding of skip counting is necessary to achieve required compete ..read more

A function can be continuous or discontinuous. There are different types of discontinuities that we will go over here. We will also show you how to determine a limit of the function based on each type of discontinuity. A function is continuous when the function is defined at every point and when a two-sided limit can be determined for every input. For example, the function is a continuous function. If we wanted to determine the limit as x approaches any value within this function, every such limit would exist. From the graph we can see that  . If we wanted to evaluate the limit algeb ..read more

A Leap Year is a year that has 29 days in February instead of 28. Every year divisible by 4 is a leap year. So, why is there a leap year? Continue reading to find out and learn how it has been calculated. A regular (common) year has 365 days. A leap year has 366 days. The extra day is “accumulated” overtime and added to the calendar year to keep it in line with the astronomical year. Julius Caesar introduced the first leap year around 46 B.C. The Julian calendar had 365.25 days in a year, which was not accurate enough and days were shifting too much compared to the solar year. The calendar th ..read more

Imagine that you want to get a new book, but it is sold out. There is a very high demand for that book, but not enough copies have been released. When the book is on the market again, it costs 10% more than before it was sold out. The book continues to be very popular and consumers are prepared to buy this book even when it costs 10% more. The new price sticks and the book is now being sold at the new, higher price. This is a basic example of how the demand-pull inflation works. Of course, the shortage of one book does not cause inflation and prices on certain items go up and down all the time ..read more

Chess board with numbers helps make the game of chess more strategic. The process of using numbers and letters to determine the position of a piece on a chess board is based on Analytic Geometry. In this blog post we will show you how to effectively operate a chess board with numbers and explain how positions are determined. PRINTABLE CHESS BOARD WITH NUMBERSDownload Understanding Chess Board With Numbers Let’s start with a simple 2-dimensional plane with a horizontal and a vertical axes. The position of each point on this plane can be described in terms of the point’s vertical and horizont ..read more

A number is an abstract concept used to compute or measure something. A numeral is a symbol representing a number. A number system is a set of numbers sharing the same characteristics. A numeral system is a combination of specific numerals. People have been trying to store and pass the information on as soon as they learned how to communicate.  The first attempts to depict numbers were done using the images of sticks or stones – mostly to count the number of items.  As civilization advanced, the need to develop numeral and number systems that would allow people to complete more comp ..read more
