Divisibilty Rules
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:
I also found a great lesson plan for this specific topic on education.com. (https://www.education.com/lesson-plan/divisibility-rules/) This type of math is introduced in the 4th grade. The lesson plan also came with a puzzle, which I attempted. Although it was a bit tricky, it was much easier to do if you know the divisibility rules. However, this can be a fun puzzle and challenge for the students to tackle!
Samra - what a helpful chart! Thank you for sharing. I agree, this class has definitely taught me a lot about understanding the math, rather than memorizing facts. I feel like most of the information we are learning I was never even taught - and if I had been it would have made math easier to grasp in school!
ReplyDeleteI will be honest, I think I was still half asleep when I first looked at that math worksheet you posted. I thought the three boxes were each a number divisible by the numbers in question, not that you were trying to make a three digit number that was divisible by both. Needless to say I was very confused. Another important lesson - read all directions! Looks tricky though because you could only use 0-9 one time, but puzzles are fun :)
Nice feedback.
