Possible Perimeters

Here are some questions that we worked on in class today. Our solutions will be posted shortly.

Perimeter

Hello, I'm Taylor, Here with my partner Ashliegh. Today we going to be speaking about how to do Perimeter.


(Taylor) I'm going to talk to you about adding together the sides of a shape to find perimeter. We can do this when all of the sides are different lengths. Like this:

Sometimes all of the sides are the same. Even though multiplying is faster, you might find it a bit hard. That's Okay, you can still just add them together! It's very simple. Here try it!

Okay, Well I am Ashliegh and I am going to be talking about using multiplication to find the perimeter of an object. So try this.




See! There that easy! Thanks so much for reading!

Solved Pattern Questions

We are almost finished our unit on patterning. Here is a slide show with the answers to some of the questions we have been working on.

Reviewing T-Tables

Hi, I'm Jagan, And my Partner Gagan, on Wednesday, our class was just reviewing T-tables. A t-table has an input and a output . In a t-table you can add, subtract, divide and mutiply numbers. The most important is that you have a rule, an example is X + 3 = Y. you can have any mathematical operation in a t-table. Every t-table has X which is the input, and Y is the output. Now try this below.



































That should have been a piece of cake! The answer or the rule is X+2 = Y.Here is how you do it in a visual image.







Now try this( it's two digit rule.) Just a clue!











Good job! I hope you got it! The answer is Xx2+1=Y. I hope you got it and heres another visual image.






I hope you understand T-tables and good luck in class. Good bye!!

Introduction to Graphing

Hi, Evan and Jack here, today we are going to be talking about graphing.
What we did on Wednesday was 2 (easy) sheets or if you didn't find them easy then we well make them easy for you. First you start off with an easy pattern like- a,b,c,a,b,c what comes next? If you have done that, you should toughen up and add another letter (ex. a,b,c,x,x,a,b,c,x,x) what comes next? A pattern is just skipping numbers, or letters in the alphabet this is an example of a pattern: 3,6,9,12,15,18. Now if you didn't get the pattern it is multiplying by 3.

Ok, now lets move onto oredered pairs, the first number is called the X, and the second number is called Y. When you do the ordered pairing the X number always has to come first, then the Y, To determine which one is X you look at the number on the X axis, and vice versa for the Y. You look at both numbers, and where the mark is on the graph, line it up with the numbers on the X and the Y axis, make sure your ordered pairs are inside bracets and the numbers should be separated woth commas.

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?

Introduction to Patterning

We have just started our patterning unit. Nicole and Erica have offered to be the very first scribes for our blog. Here are some questions that we did in class.
