BEDMAS - Order to operation

WALT: use the correct order of operations solving algebraic equations.

This week we are learning about BEDMAS, if you go to the next slide you will see the meanings to each of the letters. My partner that I worked with was Anna.v.

Sprint track

WALT: Agree on a solution that each member can explain.

Today we are leaning about are and perimeter. Here is our working out on slide 1.

Maths

WALT: agree on a solution that each member can

This week we have been focusing on perimeters and area of the field. but first we had to get into a group of 4 or 3, in my group I had Bryana and Tata. our strategy was to double both 26 and 14 to get our final answer, and we did that because it is done Side plus Side plus Side.

24-hour Times

WALT: use questions to help my understanding of other's mathematical thinking.


first day back at school, we're learning about our 24-hour time. during this activity I had a group of 3 girls, Ana.l Anna.V and myself.  there are three slides and each of us got one slide each to work, I had the first one, Anna.V had the second and Ana.l Had the third one. for e.g if it says 10 minutes to  (before) 12 , that's 11:50.

M.M.M - Mean, Median, Mode

Statistics                                                   name: Myztique and Anna

WALT- Identify the mean, median and mode within a collection of data

Activity One

Answer the questions in a different colour

The definition of the mean in a statistical investigation is commonly referred to as the average.
It is the total of all the data divided by the amount of data shown.

For example: if we have this range of data 3,5,7,1,2,3,6,8

3+5+7+1+2+3+6+5  = 32  = 4

             8         8

1. Find the mean in this set of numbers

3+7+8 +4+2+6+5+4+3+9 = 51 ➗ 10 = 5 r 1

                                               

           Find the mean in the set of numbers

4+12+5+6+11+9+5 = 52  ➗ 7 =  7 r 3

2. Find the mean in this tally chart

Pets owned by students	Number of students
Dogs	IIIII IIIII
Cats	IIIII IIIII II
Fish	IIII
Rabbits	II

  10 + 12 + 4 + 2 = 28 ➗ 4 =  7

3. Find the mean in this set of numbers

24+12+16+18 = 70 ➗ 4 = 17 r 2

4. Find the mean in this set of numbers

5+9+12+4+10+7= 47 ➗ 6 = 7 r 5

5. CHALLENGE QUESTION: Find the mean within this data, use the frequency table to help you

1+5+5+2+1+2+5+5+5+5+1+2+1+5+5 = 50 ➗ 15 = 3 r 5

Score	Frequency
1	4
2	3
5	8
Total	15

Activity Two

Answer the questions in a different colour

The definition of the median is the middle number within a set of numbers that have been put in order
from size (biggest to smallest or smallest to biggest)

For example: 2,6,4,1,9 = 1,2,4,6,9 and the middle number is 4.

BUT say if there is more than one middle number…
the median is found by taking the number midway between the middle pair of numbers:

3,6,1,4,9,2 = 1,2,3,4,6,9 → 3 + 4 = 3.5

                                             2

Find the median in these sets of numbers

1. 10,14,17,12,19,11,16

10,11,12,14,16,17,19 - the middle number is 14

2. 34,42,37,31,40  

31, 34,37,40,42 - the middle number is 37

3. 101, 167,138,124,198,149

101, 124, 138,149, 167, 198 - the middle number is 143.5

4. 54, 58,52,57,53,60

53,53,54,57,58,60 - the middle number is 55.5

5. 1001, 1094, 1023, 1065, 1038, 1027, 1042

1001, 1023, 1027, 1038, 1042, 1065, 1094 - the middle number is 1038

6. Find the median within this tally chart

Pets owned by students	Number of students
Dogs	IIIII IIIII
Cats	IIIII II
Fish	IIII
Rabbits	IIIII III
Hamsters	II

2 ,4, 7, 8 , 10 = 7

Activity Three

The mode is the most frequent number in a set of data. The number that occurs most often.

For example: In a set of numbers 3, 7, 8, 4, 2, 6, 5, 4, 3, 9 there is two modes, 3 and 4 because they appear twice in the data set.

Note- There can either be 0, 1 or 2 modes. If there are 3 or more numbers occur the same
number of times, there is no mode.

Find the mode in these sets of numbers

1. 2, 1, 5, 3, 7, 8, 5, 3 ,9 = 3 and 5
2. 1, 5, 3, 2, 9 ,4, 1, 6, 8, 0 = 1
3. 23, 45, 78, 12, 45, 67, 32, 46, 93, 12 = 12 and 45
4. 101, 121, 123, 145, 167, 121, 139, 145, 176 = 121 and 145
5. 394, 273, 219, 294, 183, 291, 273, 288, 271 = 273

Multiplying whole numbers by decimals

This week we've been learning how to multiply  decimals. One thing I have learnt from this presentation is that I find it way easier to multiply decimals now and that this activity has helped me increase my knowledge of decimals.

Intro: statistics

For this weeks activity we got introduced to statistics but a few of us already knew what statistics was all about. I was working with a buddy who is Anna and we figured out a lot of complicated equations of different kinds of graphs. 

Interacting with decimals

WALT: work collaboratively to solve word problems.

In my group we were learning about decimals.As you can see there are problems that we had to work out, and beside those problems you can see a paper that has black writing on it and that is our working out. In my group I had, Uasi, Ana.l, Anna and Bryana. It took us a while to figure out what the answers were, but we still managed to work hard and get the answer. The letter A that was beside the Number stood for (Answer). we had only three problems that we had to work out and one of these problems that we found easy was the first one : 

4.26 + 7.54 =11.8

11.8 + 3.90 = 15.7 - A (Answer)

Our second problem it took us a bit longer to get. :

30.77 + 94.65 = 125.32 - A (Answer)

30.77 

+        

         94.65        

125.32

And last but not least was our third problem :

                                                              $9639.66                                           $11872.31

                                              +                                                           -

                                                             $2332.65                                            $1780.30

                                                                     $11872.31                                    $10191.91 - A (Answer)

Introduction to decimals

WALT: work collaboratively to solve word problems.

For this weeks work we got set a word problem that includes decimals, in this presentation you are about to find out new and interesting things.

Fractions

#PROBLEM 1:

1/5 of 100 = 20

100 ÷ 5 = 20

20 x 1 = 20

#PROBLEM 2:

3/5 of 100 = 60

100 ÷ 5 = 20

20 x 3 = 60

#PROBLEM 3:

3/4 of 100 = 75

100 ÷ 4 = 25

25 x 3 = 75

  

REFLECTION: 

MOST PROUD OF: We were most proud of finally finishing this maths project.

WHAT WE STRUGGLED WITH:  We struggled agreeing with each other.

WHAT MAKES US FIGURE OUT THE EQUATION: We managed to work together and communicate at the end.

WHAT ARE OUR NEXT STEPS: To get used to working with fractions.

WHICH OF THOSE STEPS WILL COME THE EASTIEST: By sharing all our ideas that we have in mind.

WHERE WILL THE TERRAIN BECOME ROCKY: When they ask questions like, Where did you get your answer from or how? 

WHAT CAN WE DO TO NAVIGATE THE ROAD AHEAD WITH THE MOST SUCCESS: We can help each other and use all our brains to make it a successful class.

Fractions

WALT: using talk moves to clarify our maths thinking .
My reflection on this was that i learnt what the bottom and top number of a fraction is . (E.g) 2/4, the two is the numerator and the 4 is the denominator. The 4 shows us how many pieces there are , and the 2 shows us how many pieces there are.

Maths Reflection

Myztique : So in maths class we had to get in groups of four then our teacher handed out a piece of paper with numbers that lead up to 100, and we had to go one by one and circle each number from one to one hundred. we also took turns circling the number by using a colour pen, we only had three minutes to complete the task. My group was Bryana, Anna, Ana.l and myself.


Anna : Today in maths class we had to get into a group of four and get a piece of paper that has 100 numbers on it. We had three minutes to circle the number from 1 to 100 and had to take turns circling it. In my group I had: Myztique, Bryana, Ana L, and myself when we first tried we only went up to about 40 - 50 then the second time we tried we were the first group to finish which was a great accomplishment. Then we had to get into another group and on that round I was with Adrienne, Faioso, Tevarihi, and myself and on that round we were second to finish.




Bryana : This afternoon we went to our maths class and the first thing we did was our teacher put us into four groups and then she handed out a piece of paper that has 100 numbers on it we only had 3 minutes to complete the task, we had to circle the number with a coloured felt and we took turns circling the number.



Ana.L : In maths we got into groups of four or three and obviously you can see who was in our group. In my group we got to a point where we knew where all the numbers were and we got even quieter as we were finding the numbers. We had to take turns circling the number up to One hundred in three minutes. My overall experience playing was fun. We had times where we would laugh because we couldn't find the number when it was right in front of our eyes... And there were also times where we wouldn't laugh and we would take it serious.

Equivalent Fractions

Learning about Equivalent Fractions

Today Tapawha learnt about Equivalent fractions. first we had to fold up a piece of paper into half and write what the fraction was, then we folded another half and kept folding until we got to 4 folded squares. The fractions we used were 1/2, 1/4 and 1/8, as we were going through with the fractions we knew that 1/2 = 2/4, 3/4 = 6/8 and 2/4 = 4/8.
