Maths 2

2. Eva, Tamati, Noah and Jo are looking at these shapes.

Eva says, "Hey, the first shape is the odd one out."

Tamati says, "No, Eva, the second one’s the odd thing out!"

Noah says, "No, it’s the third one!"

Jo says, "Well you are ALL wrong! The last one is clearly the odd thing out."

Who is right and why? It will be the first one because the first one has no other faces.

Maths

1. Ravi enjoyed designing plans for a castle so much that he decided
2. to have another go.

This time, instead of using cubes to make the castle he has used cuboids.
(Cuboids are also called rectangular prisms).

The front view of his new castle is drawing A; the top view is drawing
B; and the side view is drawing C.

Build a castle to Ravi’s design using the cuboids.

What is the largest number of cuboids that you can use
in the construction of a castle from Ravi’s plans?
B, because it bigger then the others

What is the smallest number of cuboids that you can use
in the construction of a castle from Ravi’s plans?
B and C, because they both have 9

Can you build a symmetrical castle that is different from
any of the ones you have built so far? Yes

How many symmetrical castles can you build to Ravi’s specifications? 
2

Is it possible to design plans for a castle so that it can only
be built in one way (uniquely)?

Geometry

 Here is my Maths work of Geometry.

It was really hard but, it all paid off.

My Maths work explains how I do my Maths

and how I explain my answers. 

Treasure map maths problem

Today I solved a problem about a treasure map. How the map goes there is five squares going out and five squares going down and all together they equal to 25 squares. The problem said there were three trees going out east and 4 boulders going down south. Due to the treasure map the chest is half way between the rocks.

Dazzling Decimals 2

      Dazzling Decimals

We are learning to add and subtract up to three decimal places

What is 244/1000 as a decimal?0.244

What is 55/100 as decimal?0.55

What is 12/1000 as a decimal?0.0012

1.5 + 0.4 =1.9

0.6 + 0.9 =1.5

1.7 + 2.5 = 4.2

2.7 + 0.6 =3.4

1/10 + 0.47=0.57

5/100 + 0.25 = 0.30

0.45 + 0.42 =0.87

0.56 + 0.17 =0.73

0.67 + 0.91 =1.78

0.555 + 0.014 =0.569

0.9 - 0.33 =0.24

0.7 - 0.45 =0.38

0.55 - 0.45 =0.10

0.76 - 0.29 =0.53

2.5 - 0.78 =2.28

1.7 - 0.999 =1.299

0.934 - 0. 244=0.710

0.944 - 0. 119 =0.835

We are learning to identify the relationship between equivalent fractions.

What is 1/4 of 4? 1

What is ¼ of 8? 2

What is ⅓ of 6? 2

What is 2/6 of 12? 4

What is ¼ of 20 ? 5

What is 1/10 of 20? 2

I have 5/16 of a cake at a birthday party. I keep going back for more and eat another  6/16 of a cake. What fraction of a cake have I eaten altogether?  5/16 + 6/16 = 176/256

I have 10/21 of a cake left over from the party. Then I give 6/21 of a cake to my sisters. What fraction of a cake do I have left over? 90/441

1/2 + 3/4 =  10/8

2/6 + ⅔ = 18/18

⅕ + 2/10 =  20/50

2/6 + 4/12 = 48/72

2/5 + 3/15 = 45/7

1/9 + 1/18 = 26/162

2/9 + 4/18 = 72/162

m&m fraction

1/2 of 16 is eight 2x8=16

1/3 of 15 is 5 cos 5x3=15

Today at room 8 we made fractions with m&m and it was so fun in the beginning we had 16 but then we ate 1 and then we had 15 then the teacher named Miss Stone to make 1/5 of 15 and then i spilt them into 5 groups and then put three in each group then i found 5x3=15 and then I told Miss Stone and then she told us to eat them all and it was yummy
