## Online Peer Review with Canvas

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 online platform that can be used for peer review. Using Canvas, students can comment on other students’ homework such as term papers and essays. Here’s how Canvas works:

1.) Teacher and students create their Canvas accounts.
2.) Teacher creates a course/classroom.
3.) The students join the course/classroom
4.) Students submit work in Canvas.
5.) Students comment and give marks to other students work.

One of the interesting thing about Canvas is that the teacher can set the comments anonymously. Aside from the comments, students can also give marks based on the rubric created by the teacher. I have not explored the full capability of Canvas yet, but I think it is a very good tool for peer review.

It’s FREE, so you should try it.

## An Alternative Algorithm for Subtraction

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.

Example 1: 847 – 728

First, we separate the digits of the numbers as shown below. Second, we subtract the corresponding digits.   » Read more

## The Three Meanings of Similarity

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 are similar when either one of the following three conditions is true.

1. When one figure is reduced or enlarged, it will become congruent with the other

The first meaning is based on the definition of congruence. That is, when two figures are similar, if one figure is enlarged or reduced, then they will become congruent with the other. This definition is better illustrated graphically, using a drawing or an applet just as the one shown below.  » Read more 1 3 4 5 6 7 404
