One important concept in algebra that we learn is the distance between two points on the number line. In particular, we study the distance of a point that corresponds to a number to the point that corresponds to 0. In the following figure, the point (or circle) on the left represents 0, while the point […]
I started using an Android phone three months ago and since then, I have been searching for some apps that would fit my needs as a teacher. One of the apps that I have been using which was really useful to me is Foldersync. It enables you to sync your cloud storage with your local […]
In the figure below, lines l and m are parallel lines. What can you say about the areas of triangle ABC and triangle ADC? The distance between two parallel lines is equal at any point, so the two triangles have the same altitude (can you see why?). Further, the two triangles have a common base, […]
I’ve been really busy in the past months due to my studies. In this post, I am going to share to you one platform that I have learned in one of my courses. One of the platforms that we used in one of my courses this trimester that might interest teachers is Canvas. Canvas is an […]
In the previous posts, I have shared to you an alternative algorithm for multiplication and division. In this post, I am going to share with you a different algorithm for performing subtraction. This algorithm does not involve “borrowing” from a higher place value but subtracts individual digits. To illustrate this algorithm, let’s consider some examples. […]
We can say that two objects are similar if they look alike. In layman’s words, objects with the same shape, whether they have the same size or not are usually called similar. In mathematics, it is quite different. In this post, we are going to learn the three mathematical meanings of similarity. In mathematics, two objects […]
