subscribe post for feb.26

today in class we did number of the day, if you weren't here or forgot to write it down the number is 7923.468. Remember this is for homework everyday.In number of the day we do division, multiplication,fractions and more! Also we did not do the test because we had an assembly.

Then we have to do a balancing act. The total of this balancing act is 75. If didn't finish it's for home work.

When we were done the balancing act he gave us this question.

Find a number that is two larger then six times a number thats is half as big as seven. Write an equation and solve and verify.

Today in Math class we did Number of the Day, if you weren't here or you forgot to write it down the number was 2691.543. This is homework everyday. Sometimes in number of the day we divide, multiply or sometimes even make fractions often using the digits from the number of the day.

Then we continued our Math Links on pages 398- 401. A reminder that our quiz tomorrow( It's a Thursday, there's no surprise) is going to have similar questions to these pages. Mr. Isfeld said it would be fine if I only gave examples, instead of every single question.

Here are some examples:

Draw a balance to show the equation 12=3+M, if M represents an unknown mass.

B) What total mass should be on each side of the balance?

C) Solve the equation to determine the unknown mass.

These aren't in order, they're only EXAMPLES!!!

The average life span of a grizzly bear is 25 years. This is 15 more years than the average life span of a cougar.

A)What equation will model this situation?

B) What is the average life span of a cougar?

At the Commonwealth Games in Australia, Canada won 86 medals. This was 24 fewer medals than England won.

A) Write an equation to model this situation.

B) How many medals did England win?

Shawn received $5 change from $20 when he bought some binders. how many binders did he buy if each binder costs $3.00? Write an equation, then show how you solved it.

Today we did number of the day. The number was 8394.162. As you probably already know it is homework every day.

In class we did work in the math links text book, we did pages 398 to 400. It was mostly algebra and some scales. Here are some examples:

1.Wes is solving a problem. He models it to start

2. Use mental math to solve each equation. Explain your thought.

A) Z+7=42 B) G-2=5 C) N-4=8 D) 9=K+6

3. Ryan has a bag of oranges. His friends eat ten oranges. If there are 2 oranges left in the bag, how many oranges were there to start with?

A)Model the situation using cups and counters or sketch of a balance.

B)Write an equation to represent your model.

C) Solve by inspection(inspection means mental math).

These are some examples(not in order).

Sorry if there was no links and videos, please comment and tell me if there was any mistakes.

Today in class, we did our number of the day. Just in case you were away, the number was 6918.205. Make sure you finish it everyday. 

Mr. Isfeld showed us the correct answers from our test yesterday. 

                                      

   VERIFY 

     a+5=11                        a+5=11

 a+5-5=11-5                    6+5=11

         a=6                            11=11

     b-3=7                          b-3=7

b-3+3=7-3                    10-3=7

         b= 10                          7=7

    c / 5 = 25               

5 x c/5 = 25 x 5

           c=125

    6d/6=30/6                   6d=30

           d=5                       6(5)=30

                                           30=30

    7e+8=29                   7e+8=29

7e+8-8=29-8            7(3)+8=29

     7e/7=21/7               21+8=29

           e=3                         29=29

      2f-2=8                           2f-2=8

 2f-2+2=8+2                  2(5)-2=8

     2f/2=10/2                    10-2=8

           f=5                                8=8

    g/3+2=7                     g/3+2=7

g/3+2-2=7-2                15/3+2=7                       

         g/3=5                         5+2=7                    

     g/3x3=5x3                         7=7

             g=15                         

     h/4-3=2                h/4-3=2   

h/4-3+3=2+3         20/4-3=2

         h/4=5                     5-3=2

     h/4x4=5x4                    2=2

             h=20

              

4x+2+3x=9               4x+2+3x=9

       7x+2=9          4(1)+2+3(1)=9

    7x+2-2=9-2               4+2+3=9

        7x/7=7/7                    6+3=9

              x=1                             9=9

Then Mr. Isfeld gave us a word problem. The problem was the following question:

There are 2 more than half as many boys in class as girls.  If there are 12 girls, how many boys are there?

The solution to this problem is:

6x2+2=d              6x2+2=d                                                There are 18 boys in class.

   12+2=d              6x2+2=14

        14=d                12+2=14

                                      14=14

After that, Mr. Isfeld gave us a question right at the end of class and we had to do it. 

So here is the answer. 

6 + 4 / 2 - 4 x 2 =

6+2-8

8-8

0                                           

Mr. Isfeld gave us the answers for the balancing act.

Today in math, we started with the number of the day. Just in case you were away, or did not write down the number of the day, the number was 5214.897. It's very important to get your number of the days finished, because sometimes you may have to hand it in to go to special events like dances.



Since today was Thursday, we had a math quiz. Because we have math quizzes every Thursday.

On our math quiz, we had linear equations like, a+7=10, d-4=5. We had to solve, and then verify each of the questions. There was a total of 10 questions on the math quiz. We did not get to correct the test in class, so we handed them in to Mr. Isfeld at the end of class.

Also, if anybody in class was done the quiz before class ended, we were given a balancing act to solve. The total weight is 50. Some strategies you can use to solve these questions, is to divide the total weight by 2, so you can make it easier, then at every arm or split, you can divide by 2. Although, this puzzle is more difficult, because there are objects in the way of the arms. If you have not finished this in class, it is homework.

1) 5+x=16





2) 4+x=9





3) x+4=9





4) x/6=3





5) 4+x=14

12) 3+x=15





13) 6x=30





14) x+9=21





15) x+7=7





16) x+4=7





Next Page:





51) 59= 5x+6x+4





52) 6x+6+3x=105
