EXTREME ENVIRONMENTS

4/23/2019

Today, the students worked in their groups for Novel Approach, sharing their learning with each other. They then moved on to practice the pre-test for Word Work before recess. After recess, the students continued to listen to the adventures of Will in the Boundless, and practiced using integrals to solve problems. After lunch, the grade 7s worked on wrapping up their electromagnetism unit by building their motors, while the grade 6s started a new joint-science unit with Division 3, learning about EXTREME ENVIRONMENTS.
Everyone enjoyed some active-time at the end of the day, playing ultimate, basketball, and otherwise running around.

IMPORTANT REMINDERS:

1.) To prepare for earthbites tomorrow, ALL STUDENTS are expected to bring a cap from a bottle of some sort (wine, 2 litre of pop, etc), and a creative, handmade greeting card.

2.) This is a reminder for those students who will be writing the Math Test at Churchill on Thursday, April 25 at 4pm. You will be writing in Room 110.

3.) Gr. 7 Celebration - Please submit your $25 to Mr. Hong/Collins ASAP. Also, we are asking for 3 different photos of each of you (Toddler, K-3 photo, and recent photo).

1.) MATH:

Pg. 274 Reflection A
Pg. 275 Qu #1-8

2.) SCIENCE:

Grade 6: Be sure to think about and bring any materials that will be useful for creating a glove that will protect you from the very cold (deep sea, polar regions)
Grade 7: Complete inquiry journals by Thursday.

3.) WORD WORK WORDS:
Reluctant, cajole, trove, valise, cordon, festoon, squall, searing, exasperation, intriguing, scoff, clench, delectable, emanate, apprehensive, undulate.

4.) POST A RESPONSE:

When we are doing integer problems like (+6) - (-4) we get the bizarre answer of +10. How can we explain this?
What INTEGER RULES can you come up with to explain how to make integer addition and subtraction easier for someone who hasn't done it before?
Are there ways that we can re-write the above problem (and others) so that it becomes easier to understand?

We were doing integers and learning how to guess the numbers by reversing it. I added (-2)-(-4) and the answer was two due to the parenthesis separating the integer from the expression sign. After I tried a couple of examples, I learned that a negative plus another negative becomes a positive and a positive plus a negative becomes a negative. Still, math is hard but this made it seem easy. In conclusion, if you keep trying and giving examples, you can make things easier to understand.

Subtraction:
If both numbers are both positive/negative then you can ignore the sign and do the simple subtraction. Then add a negative/positive sign to the number and that is your answer.
(-6)-(-3)=(-3)
If you are subtracting a negative number from a positive number, reverse it. Change subtraction to addition and change the negative number to a positive number.
(+2)-(-5)=(+7)
If you are subtracting a positive number from a negative number, treat it as an addition question.
(-5)-+(+7)=(-12)

Addition:
If both numbers are positive/negative then you can treat it as a simple addition question.
(-6)+(-8)=(-14)
(+6)+(+8)=(+14)
If you are adding a positive number to a negative number, add in the direction of 0.
(-6)+(+9)=(+3)
If you are adding a negative number to a positive number, subtract.
(+3)+(-6)=(-3)

@shannon
I like your response. Thank you for all the detail.
For those last two:

"If you are adding a positive number to a negative number, add in the direction of 0.
(-6)+(+9)=(+3)
If you are adding a negative number to a positive number, subtract.
(+3)+(-6)=(-3)"

Can you think of a way that you could use the same rule for both? Does the order that you add them in matter?

4/23/2019 07:54:23 pm

6-(-4), how can we explain that? well let's start from the first number, six. Take that and minus negative 4, wait a minute! How do you subtract subtract something? well do the opposite of minus, plus. So 6-(-4) is basically just saying 6+4. now that's easy, ten! but how did I get that? I will explain with a true statement. If the first number is positive and the second is negative(can be plus or minus), then it is the same to switch the sign to it's opposite and also change the second number to it's opposite.

@RZ
I like this response! Can you go into more detail? What other rules can you come up with? for instance: (-6) + (+4)

4/23/2019 08:03:08 pm

6-(-4) =? Its so easy! the number has to be smaller than 6 because it is subtraction. And subtraction is taking away stuff! The answer is... 10?!

The reason this equation ended up bizarre was, that you were subtraction a negative number. If you add a negative number, than you will gain a "lose 4" which means you will get to lose 4. In subtraction, if you lose a "lose four", then you are basically losing a subtracted number, so you are adding the number back. A rule that can be is two positives make a positive, two negatives = a positive, but a + and a - equals negative. So 1-(-1) is the same as 1+1 because there is two negatives. but 1+(-1) is 1-1 as there is one positive and one negative. So to make the question simpler, you can change the equation to 6+4.

your par was almost perfect! maybe you should try something extra, try explaining how to calculate it on a number line. (This is not necessary at all, just a suggestion to make you "perfect par" even more perfect)

lets say that 😀 is positive and 😡 is negative.

(+6 )-(-4) = (+10) why? because (+6 )-(-4) is the same as (+6)+(+4)
that is why (+6 )-(-4) = (+10)

Raymond

@harmon
please provide more details and also explain why (+6)-(-4)=10 and why it's the same as 6+4.

My rules of integers subtraction and addition is:

In integers, if the sign is both negative, then we just follow the first sign or more easy to understand, we just follow the simple addition and subtraction. For example, (-1)-(-1)=0. In the other hand, if you are hand, if you are adding both positive number, then just also pretend we are doing the simple addition. For example, (+2)+(+2)=(+4). It’s very easy right? let’s do something harder.

If the question is (+5)+(-2)=(+4), the answer is always smaller than the original number. If you flipped the positive and the negative, the answer is the same.

Although subtractions might seems a little bit confusing at first. Once you get the hang of it. I promise I would be a lot easier.

For a question like (+6) - (-4), we could easily turn the two minus sign into one adding sign. Such as. *(+6) + 4* which equals to (+10) at the end.

Subtraction
Starting with subtraction. (+6) - (-4) is a perfect example of a question that has both positive and negative numbers. But what if there’s two positive or negative? How are we going to subtract these? Well, it's tricky since it’s basically the same. Instead, if we’re using a number line. We’re going to subtract the opposite way. An example for this would be, *(-6) - (-5) = ?* First, we got the negative 6, and then we’re heading 5 numbers towards on the positive side. Which is going to end up like *(-6) - (-5) = (-1)* = *(-6) + 5= (-1)*

Addition
Unlike subtracting, adding is much more straightforward. Because of the same thing as adding numbers, but within both positive and negative numbers. For example, (+3) + (+9) = (+12).
For instance, (-5) + (+7) = (+2).

To sum up, adding and subtracting are pretty easy when you got the hang of it. In addition, if we’re looking for a way that’s going to be easier for us to understand, we should probably use strategies like labeling numbers down on a number line. This way the whole process is much organized. No doubt, it’s definitely a good way to practice if you’re new to integers.

(+6)-(-4) = (+10), but how?

Basically if you subtract a negative number from a positive, you just change the subtraction of the equation and the negative into a positive. So in this case, (+6)-(-4) is (+6)+(+4), which equals (+10)

Pretty sure you missed one or two criteria points for your P.A.R. Also try putting more detail, because right now it looks like you just randomly and quickly posted the P.A.R. because you want to go play video games or something. (sorry if that's not true, I said it just seems like it)

So, (+6) -(-4) how to do explain this equation. First we take the +6 and plus it with the -4 equal to +10. +6 - -4 is like +6 - +4. You would use counters and number lines to calculate this equation.

Today was the first day back from a long weekend, and we had resumed our progress in learning about integers. Around last week, we learned about different types of equations, and how negative and positive numbers will alter a result. One example of this is subtraction. when you subtract a number, it will obviously decrease, but when you are using a negative number, things become slightly more confusing. When you add a negative number, the number is decreasing, with that logic, if you subtract a negative, you are adding to the number, because you are removing a negative substance from it. As an example, we have (+6) - (-4), which equals ten. If we take a look at both numbers, the 6 is positive, and a negative 4 is being subtracted if you remove the negative four from ten you are technically adding 4, because you are removing a negative, this means that (+6) - (-4) equals ten.

I have been hearing these overly complicated rules about subtracting integers, but there is such an easy way to describe this rule. When subtracting, the roles of the numbers are reversed, as an example, if you are subtracting (-10) from (+10) you are adding ten because removing the negative. On the contrary, if you subtract (+10) from (+10), you will get zero because you are removing a positive. By simply switching the signs, you create a much simpler equation than having to spend 10 minutes working with a silly number line.

Using the simplified rules I created, we can simplify (+6) - (-4) so that we do not have to spend too long using a number line. The answer to this question is ten, and we can get to ten by simply adding one step. If we transform all negative signs into positive signs, you receive a very simple addition question, 6 + 4, the answer to that question is ten. This rule is able to help simplify any question that comes your way. Use it, it helps.

Four days of break really gave us a lot of free time. We were able to go out and have fun for while. After that however, going back to school seemed boring and unappealing. School keeps surprising me though and it was as interesting as ever...like our math unit.

At this moment, we are learning about integers and how to add and subtract them. There are quite a lot of rules to do these and many confusing things that get easier as you learn them. For example, the question +6-(-4) might seem like the answer will be +2 but that is actually incorrect. Since there are two negatives, that means that they actually equal a positive. Therefore, the answer will be +10.

To make things easier for people who have never learned integers before, we can talk about some rules that you must know first. Some of the general ones are that two opposite signs mean negative or subtract and two of the same sign mean positive or add. The Zero Principle also states that if two numbers of opposite signs are added together, they will always equal zero.

The above problem may still seem quite difficult to some people, so we can change parts of it to be easier to understand. First, one way is to switch around the signs. The moment you see the negative sign, you know that it immediately flips around whatever else is beside that sign. There are two negatives, and that makes a positive and therefore we can say that the question is actually (+6)+(+4).

In conclusion, integers are just very weirdly placed numbers. With the right knowledge and little tricks, they really aren't very difficult at all.

My way of subtracting integers and adding integers is. If the sign is both negative for example (-3)-(-4)=? then we just have to turn it to (-3) + 4 = ? (because negative plus negative equals to positive) which (-3) + 4 = (=1). on the other side, if you are adding both positive number, then you are only doing the basic addition. ( Because +1 = to 1) An example would be (+9)+(+3)=(+12). So now if there is a question (+11) - (-33)=(+44) the answer will always be a positive because negative plus negative equals to positive.

Integers! On a number line there are number 0 +1 and -1 etc. Some of the basic of integers is that when theres two negatives it converts to a positive but if its positive and negative it will stay negative. When looking at the equation +6-(-4) we need to remember that two negatives equal positive so the equation will turn into 6+4, after that you must add both numbers which create +10.

So now that we know how to answer let's see if we can rewrite this equation.
-(-4)+6
-(-6)+4
These are two ways I know but, remember that when doing equations with integers two negatives equal positive. When we have 2 positive it stays positive and when there's a positive and a negative it converts into negative.

Math, a subject that many people don’t really enjoy. They think that it is hard, confusing, and tedious. That is the case of when you don’t know what to do. When you know the rules and explanation to things, math can be surprisingly pretty straight-forward and easy! We have been learning about integers for the past few weeks. We have learnt different ways to add and subtract positive and negative numbers. There are different rules you have to be careful of when doing operations with these confusing expressions.

Let’s take the example of +6 - (-4). This is actually equal to 6 + 4. Here is why. Like multiplication and division (with positive and negative numbers), two positives or two negatives have a result in positive, while one of each (regardless of its order) will result in a negative. Consequently, the two negatives (- (-4)) will then become (+4). Though, be very careful of where you use this rule. People get this mixed up with the expression itself. This rule is only for when you have two signs beside each other. If you somehow don’t believe me, we can prove it with math. We all know that we can check our answers by reversing the equation. In this case, +6 - (-4) = 10 can become 10 - 6 = 4, therefore proving that - (-4) is equal to +4.

To sum it up, this is what you do when you come across two signs beside each other. This may sound very complicated for some people, but when they start to use number lines and counters to show the equation, it will be clear to them.

(+6) - (-4) =? How can we find the answer?

Here's how, first if you are to now how to add or subtract integers, you just know what the signs mean ( addition, subtraction, negative, positive ) and in this case the two negative signs and when you have that you simply just add both the numbers so in this case (+6) - (-4) = (+6) + (+4) = +10
Yeah you will now be able to solve more and more along the way!
