Math Trick: Multiplying by using lines.
I found this video online and I found it to be interesting. I would like to know what you think of it and how you might use it for multiplication. Do you think that it would be an alternative way to teach multiplying or not. I would like your thoughts on this topic.
Multiplying using Lines
This video was interesting, but I think it can be easily messed up. I think it would've helped me to catch onto multiplication faster. I don't think that it should be the main way multiplication should be taught, but it should be used. I feel like students, including myself, would mess up the lines very easily. It seems like there are too many rules. I would confuse myself if there was a zero in one of the numbers. It bugged me how he said he was going to say the reason that this method works, but instead went into the factoring problem. If some reasoning would be given or all of the rules were stated, I would be more trusting with this method.
ReplyDeleteLike Amelia, I thought this video was really neat and interesting. I really enjoyed seeing how the method worked. I do not think that I would ever use this method though because I feel that there are too many rules to remember. I could see how this method would be beneficial to some students though. I agree with Amelia when she said that it should not be the main way that multiplication is taught, but it could be used as a tool to help with the understanding. I remember in sixth grade, Mrs. Keesling taught our class how to use lattice (I think that is what is called) to solve multiplication problems. When she first taught us this method, I thought it was the best thing ever! It was just a tool to help us understand multiplication though. Now, I have no idea how to use lattice! I have not done it since sixth or seventh grade! Aaaannnnnnyyyyyyway, I think that this is a very interesting and neat method to use, but it should not replace our current teaching style of multiplication.
ReplyDeleteMr. Oliger,
DeleteThe clock on this blog is incorrect. It says that I published this at 4:33 PM. I most definitely just posted this, and it is 7:33 PM.
I think that this is an interesting way to teach multiplication; however, I believe that it does not make a significant difference from the conventional way that we were taught. This method may be quicker for larger numbers, but for numbers less than 100 I think that regular multiplication would work fine. Also with the line number problems, the larger your number characters (like 7, 8, and 9) the more lines you will have and the more messy your multiplication will be.
ReplyDeleteLike the other three, I agree with the fact that this should not replace the traditional method. I think there too much room for error. The grouping is what would mess me up the most. That being said the student I tutor struggles with multiplication immensely. They constantly have to refer to a multiplication chart. I actually am going to try to introduce this method to them during our next session. I think it could be extremely helpful to them in the future.
ReplyDeleteIt wouldn't let me correct my error. **
DeleteMother of pearl. It is being stupid. Okay, **there is too much room for error.
DeleteThis is awesome. Really cool stuff. BUT, it lacks the efficiency. It isn't quick. And like Amelia said, this can be way too easily jacked up. And the last thing I want is for my multiplication to look like Michael's. :D. However, the concept is utterly astonishing. Crazy cool tricks to show your friends, yes. Effective math method, NOOOOOOO
ReplyDeleteIf this was the first thing I ever saw about multiplication I think I would like it. I would have originally liked to learn like this and I believe that the younger generation should be shown this. I think it's a cool way to visualize what is going on and therefor would make a useful learning tool
