So, you want to learn about patterning?

Well you’re in luck because today we’re going to make it all clear… That is before we get to the hard stuff.

I’m your host Nicole, with my partner Erica, together we’re going to make patterning as easy as pie, or should I say pi? Sorry, a little math joke there. Now, this not your average “a b c a b c a b-what comes next?” that you learned in Grade 1. Oh no, we going to be learning input/output. We’ll do more later, but for today that’s all you have to learn.







The X column represents the input. And the Y column represents-you guessed it-the output. So now what we have to figure out is how to we get from the X to the Y. First let’s start with the 1 turning into a 3. Let’s try something simple, like adding 2. 1+2=3. That works. Now we have to try it with the other numbers. 2+2=4. No, that doesn’t work, so let’s try something else. How about multiplying be 3? 1x3=3. So that works for one. 2x3=6. So it works again. 3x3=9.4x3=12. 5x3=15. So we have found our answer. Now to write the rule: Xx3=Y. Now that my look confusing to you, but really it’s very simple! See since X represents the input, and Y represents the out put, and you have to multiply be 3 to get from X to Y, Xx3=Y.





Now let’s try a chart with a slightly harder 2 step rule. Don’t worry, we’re not going to get into rules like Xx4-5x2+2=Y.




Let’s get to work on this problem. Now let’s try multiplying by 2, then adding 2. 1x2=2+2=4. So far so good. 2x2=4+2=6. Uh oh, that doesn’t work. Lets try again, how about multiplying by 3, then adding 1. 1x3=3+1=4, well, it passed the first test. 2x3=6+1=7, looking good. 3x3=9+1=10. 4x3=12+1=13. 5x3=15+1=16. There, we found out our answer.



Now the rule: Xx3+1=Y. So that’s all you need to know about input and output. We will see you next time on the 6BD math blog. Here are some journal questions about input and output:
What do you know about patterns?
What do you still want to learn?

good job Nicole it was really good. You explained it well.I think everybody would understand.just so you know you made two mist5akes

dear, erica and nicole

i think your post is great and your working together as partners really boosted the post, and you guys really made it interesting for people to learn math plus on top of that you guys made it easy to understand.So on that note i would jus like to say you guys did a great jod.!

I think Nicole and Erica did a really good job of explaining how to do the patterning and i could understand everything. I think they did an excellent job.

Nicole said...

Yes, a couple people have told me that I made a few mistakes, and I don't care!!!

To answer the question:What do you still want to know about patterns?: Well, I always used to think that patterns had to repeat themselfs to be a pattern, but lately I've been wondering, does a pettern have to repeat? Like on wood, it looks nice, and has a series of knot holes and oher things, but it doesn't repeat. So, would it still be a pattern?

Good job Erica and Nicole! You explained it very well 1 I understand what you're talking about! I know most patterns repeat themselves, or show the same thing over and over like what you guys explained! I'd like to learn if any patterns don't repeat. Well good job and you made a few mistakes, bye!

Dear Nicole and Erica,

You did a great job explaining how to do input output for people who might be having a difficult time on it. Something you did well, was starting with an easy problem and doing it step by step. Good job!

Ruby said...

Hey Nicloe and Erica,
You did a reall good job on exsplainng how to do patterning. I just used to get it now i reall=y get it, I just used to hope that my rule was closer and i just used to check on one or two. Now i check on all to make sure the rule work:). Anway u guys did a great job. Great explenation of patterning. You have and will help a lot of people

you guys did good job. you explained it very good and it made me to do it more easier.And I think if the other people rad they would say interesting or good so I'm just saying that you guys did good.

Taihyun said...

good job on the post it was really good. I really undrestanded the input and the output. you two had a great post and I think everybody
would understanded the post. But great job on the post.

jagan said...

good job on the post it was really good. you two had a great post and I think everybody would understand the post. You guys explained very good. Good Job!!

ilhan said...

You guy did very good job. I could understand easily and I think i understand.I just want to say you guys did very good job.

Jackson said...

hey! Great Job!you guys explained patterning so well! I think everyone will get that type of patterning! so ya great job!:)

lara said...

hey you guys a pretty good job and i understood it kinda. because you guys made a few mistakes.

other than that it was good

later lara:P:P:P:PP

Matthew said...

Great job nicole and erica. I think you did a great job making it easy to understand, but you did make a few mistakes. anyway exellent job

Brenden said...
