Equality Vs. Inequality

You may have been introduced to this last year, but if not, I’ll copy out the introduction that I previously used for the Grade 1’s.

Today I would like you to practice identifying if an equation is equal or not. For example, you’re used to seeing equations like 5+5=10 and 8-5=3. Now pretend that the = sign is like a wall. When we are looking to see if things are equal in math equations, we want to know if the value of the numbers on each side of the = sign wall is the same. For example, for the equation 5+5=10. On the left side, there is 5+5, we know that equals 10. On the right side we have the number 10. So on each side of the wall the value is the same. Again, with 8-5=3. Pretend the = sign is a wall. On the left side of the wall we have 8-5, which we know equals to 3. On the right side of the wall we have 3, so on each side of the wall the value is the same. In both of these situations, there is an equality.

Now what about 4+5=10? On the left side of the wall we know 4+5=9. So on the left side of the wall, the value of the numbers is 9. On the right side of the = sign wall is 9. Is this equation equal? The answer is no. 4+5 does not equal 10. The values on each side of the wall are unequal so there is an inequality. For this equation would we show that it’s an inequality by using this sign: ≠.

We can also do this with simple equations too.

If I have 5+5=6+4 is this correct? Should there be a = sign or a ≠ sign?

On the left side of the = sign wall there is 5+5 which we know equals 10. On the right side there is 6+4 which equals 10 too. So is there an equality or inequality? There is an equality because both sides equal 10. 

Try this worksheet and see if you can figure out if you use a = sign or a ≠ sign!

Grade 1’s: Double Digit Addition

Try to do the worksheet below. We haven’t practiced math with double digits like this in a while, so it might take some practice to get back into it! There is one worksheet without regrouping (carrying the one) and there’s another with regrouping. If you aren’t ready for the second worksheet, then just stick with the first. If you do not have a printer, please don’t feel that you have to do all of them, feel free to pick and choose some to do on a blank sheet of paper.

Here are the videos showing how to do the math if you need to watch them:

Grade 2’s: Unknown Numbers 

Today we are going to practice figuring out the missing number in an equation. For example, if I had this equation, 2 + ___ = 4, what would go in the missing space? We know that 2+2=4, so 2 must go in the missing space. These equations are just like normal equations, but are shown differently and the answer is given, while one of the numbers that had to be added or subtracted is missing!

Another example, _____ + 5= 15. For this question, I have to figure out what number goes in the missing space. If I don’t know the answer right away, I can practice with objects like pencil crayons. I would count out 15 pencil crayons, set aside 5 and see how many are in the other group. If I did this, I would see that 10 pencil crayons in one group plus 5 pencil crayons in another group equal 15.

A trick to use is this, if the question has addition or a plus sign, then I can use subtraction to figure out the missing number. For ____ + 5=15, I could switch it and do 15-5 which would equal 10.

You can also use drawings to help you. In the first picture, I wrote out the equation ____ + 5 = 15. Then I drew 15 dots or circles. We know that something (a mystery number) plus 5 equals 15. So I coloured in 5 of my circles in blue.

Then I looked at my picture to see how many were left. I could see that there were 10 remaining circles. So 5 blue circles + the 10 remaining circles which I coloured in red = 15.

This can be a really tricky concept in the beginning, so if you find it difficult don’t worry! Just keep practicing.

Grade 1’s: Equality vs. Inequality 

Today I would like you to practice identifying if an equation is equal or not. For example, you’re used to seeing equations like 5+5=10 and 8-5=3. Now pretend that the = sign is like a wall. When we are looking to see if things are equal in math equations, we want to know if the value of the numbers on each side of the = sign wall is the same. For example, for the equation 5+5=10. On the left side, there is 5+5, we know that equals 10. On the right side we have the number 10. So on each side of the wall the value is the same. Again, with 8-5=3. Pretend the = sign is a wall. On the left side of the wall we have 8-5, which we know equals to 3. On the right side of the wall we have 3, so on each side of the wall the value is the same. In both of these situations, there is an equality.

Now what about 4+5=10? On the left side of the wall we know 4+5=9. So on the left side of the wall, the value of the numbers is 9. On the right side of the = sign wall is 9. Is this equation equal? The answer is no. 4+5 does not equal 10. The values on each side of the wall are unequal so there is an inequality. For this equation would we show that it’s an inequality by using this sign: ≠. 

We can also do this with simple equations too.

If I have 5+5=6+4 is this correct? Should there be a = sign or a ≠ sign?

On the left side of the = sign wall there is 5+5 which we know equals 10. On the right side there is 6+4 which equals 10 too. So is there an equality or inequality? There is an equality because both sides equal 10. 

Try these worksheets and see if you can figure out if you use a = sign or a ≠ sign!

Grade 2’s: Rounding 

Today we will practice rounding to the nearest ten. What is rounding? Rounding is when we take a number and find the closest number 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 that it is next to. We do this when we estimate a measurement, or need a general idea of how much there is of something or how long it is. For example, if I have the number 26 I have to think, what numbers is it between or close to (that are a multiple of ten)? Well on a number line 26 is between 20 and 30. Now what is the half way point between 20 and 30?

20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.

25 is right in between. Now I have to think, is 26 below or above, before or after 25? It is above 25, because 26 is more than 25, it comes after it on the number line. On the number line you can see that 26 is closer to 30. So if I was rounding to the nearest ten, 26 would be rounded to  30.

We can also round to the nearest 100th. For example if I have the number 123. I would have to think, is it closer to 100 or 200? On a number line it would be closer to 100 rather than 200.
