Divisibilty Rules

Image
As we are progressing through the semester, I have definitely seen the value in learning and really understanding math, instead of just trying to get to an answer or use memorization. Although memorization is necessary in some instances, it is better to understand the actual math because not only can it help save time while doing a problem, but it can also set a strong foundation for learning more complicated math. I found a great resource for learning about divisibility rules which can make division a bit easier and faster, especially when trying to divide large problems. Just like with learning fractions and being able to quickly compare two values by seeing whether they are greater or less than 1, 1/2, etc, you can make division of long problems easier by knowing the divisibility rules. The divisibility rules are as follows below: http://www.resourceaholic.com/2016/07/divisibility-rules.html I also found a great lesson plan for this specific topic on education.com. ( https:...

Lines, Line Segments, & Rays Oh My!

Image
According to the common core, students moves from learning about square units and area in the 3rd grade to learning about lines and line segment in the 4th grade. So the next stop on this geometry train is learning about lines, line segments, and rays. One of the major obstacles in learning about something is not knowing the proper terminology. I believe that students need to have a strong foundation to help them excel further in math.  I found a simple chart that provided the term, a physical representation, and definition for these terms. https://www.mathworksheets4kids.com/line-ray-segment/chart1.pdf This was a good refresher for me for the different terms that are used in geometry. We all know what points and lines are but they have specific connotations when used in geometry. I also went through a quick video I found on Khan Academy that further reinforced my understanding about how these terms are related and how they are the same. After the video, there was a review...

Comparing Area and Perimeter

   After the previous post on area, the topic moved into the direction of perimeter. While I had a basic understanding of both these concepts (to get area you have to multiply two sides and for perimeter, you have to add up all the sides), I realized that this may be confusing for some students. They might be able to pull of the lower level skill of computing the problems, but this course has shown me the benefit of understanding the topic conceptually. So I set off to find a way to help students conceptually understanding what it means to find the area vs. finding the perimeter. I went to khanacademy.com and they briefly talked about the comparison between area and perimeter, but I think students needed another way for it to be shown to really understand it. Below is an example of a sample question from Khan Academy. I found this website, which I think did a good job of easily explaining what each term is and how to compute the problem. https://www.mathplanet.com...
