If you have a blog about K-12 Mathematics, or about mathematics teaching, you may want to submit your articles to the carnival. Submitting articles to the carnivals will expose your blog to more readers.

That’s all for this week. Have a BLESSED weekend. 🙂

Regular Tessellations: Why only three of them?

In Tessellations: The Mathematics of Tiling post, we have learned that there are only three regular polygons that can tessellate the plane: squares, equilateral triangles, and regular hexagons. In Figure 1, we can see why this is so. The angle sum of the interior angles of the regular polygons meeting at a point add up to 360 degrees.

Figure 1 – Tessellating regular polygons.

Looking at the other regular polygons as shown in Figure 2, we can see clearly why the polygons cannot tessellate. The sums of the interior angles are either greater than or less than 360 degrees. » Read more

In the previous blog tips post, I have given you 7 tips on what to consider and what to do before starting a blog.

When I say early stage, I mean during the first three to four months.

Before we begin the discussion, let me reiterate that the golden rule of blogging is to ⁸write quality and original content. Even if you follow all the tips that I am going to discuss here and in future posts, if the quality of your content is poor, it is more likely that your readers will not come back, and they will definitely not recommend your blog.

The following are the things that would recommend to do during the early stage of blogging.
