Geometry

Today I have learned to make 5 different things with only 5 triangles that are the same size.

Tangram

What I have learned while I was making these shapes: I have learned to make different shapes with only 7 tangram.

Today I have spent the morning using 5 triangles, 1 square and 1 parallelogram. These pieces are called  tangram. With these pieces I have made these 7 shapes.

Addition and Subtraction level 3

I am able to solve addition and subtraction problems at level 3.

Addition and Subtraction.

Show how you solve these number problems.  

1.  Maraea is saving to buy a cat.  In 3 weeks she has saved $9, $56 and $72.  Show how to work out how much she has saved altogether. 9 + 56 + 72 = 50 + 70 = 120 6 + 2 = 8 9 + 8 = 17 120 + 17 = 137                                       ANSWER- 137.

2.  Tom saves his money each month to buy a dog.  In 4 months he has saved $36, $78, $203, and $123.  Show how to work out how much he has saved altogether. 36+78+203+123=? -4 from 8 then put the four to the 36 = 40. then there will be 40 + 74 + 203 +123.   40 plus 70 = 110 + 4 = 114. 200 + 120 = 320 + 3 + 3 = 326. 114 + 326 = 440. Answer-440-

3.   Te Ao is saving to buy a horse.  So far she has saved $17, $160, $72, and $148.  Show how to work out how much she has saved altogether. 17 + 160 + 72 + 148 = ? 160 + 148 = 308 17 + 72 = 89 308 + 89 = 397.                         Answer-397-

4.  Petelo has $ 147 as a present.  He spent $78 at the shop.  How much has he got left? 100 - 78 = 22 22 + 47 = 69                                                        Answer-69-

Multiplication n Division level 3.

I am able to solve Multiplication and Division problems at level 3.

1.    When Jasmine makes lemonade she uses 6 lemons for every litre of water. How many lemons does she need for i)     2 litres of water?    12 6 Lemons makes 1Ltr. I doubled the lemons to make 2Ltr. Therefore since I doubled the lemons, you’ll need 12 lemons for 2 litre of water. ii)    3 litres of water?    ____18______ 12 lemons make 2 litres of water. so I just add another 6 lemons. which makes 18. she’ll need 18 lemons for 3 litres of water. iii)   10 litres of water?    60 I times 6 lemons by 10 litres = 60 lemons for 10 litres.

2.   Devinda is doing some baking. When he uses his mum's recipe he can make 8 muffins. When he doubled the recipe he gets 16 muffins. How many lots of the recipe does he need to make i)     24 muffins?     recipe times by 3. . ii)    32 muffins?     recipe times by 4. iii)   56 muffins?     recipe times by 7.

Fraction Level 3.

I am learning to solve fraction problems at level 3.

This task is about finding fractions of a given number.

A farmer is selling some of his animals. 1.  The farmer sells ¼ of his 72 cows.  Show how to work out how many cows he sells. Half of 72 = 36 which is 2/4 of 72. Half of 36 is 18 so then 18 is 1/4. The answer is, the farmer sells 18 cows.      Answer- The farmer sells 18 cows.✔

2. He sells ⅓ of his 45 pigs.  Show how to work out how many pigs he sells. Put into 45 into 3 groups. So each group will have 15 pigs. Because 15 + 15 + 15 = 45. So the farmer sells 15 pigs. Answer-  The farmer sells 15 pigs✔

3.   He sells ⅙ of his 84 sheep.  Show how to work out how many sheep he sells.     First I share 84 into 6 groups. I firstly put 10 into the 6 group.  Then I have 24 left. I  divide 24 into 6 groups = 4.  Therefore 10 + 4 = 14. 14 sheeps is 1/6 of 84 sheeps. Answer-14 sheeps sold. ✔

Water Presentation

This week I have been studying water. I was put into a group of three.  This is what my group and I created.


Here are the links to my awesome group:

Petelo  &  Salamona.

Maths

Iritana planted 5 rows with 14 lettuce in each row. How many lettuce did she plant altogether?

 Strategy:Doubling & Halving.
Number sentence:5x14=
           
1. First I double 5 = 10. 
2.Next I half 14 = 7.

  Therfore the number sentence now is 10x7.

3. Last of all we multiply10 with7 = 70.

  Which is the same as 5x14.

( 1.5 x 10=50
2.5 x 4`= 20
3.50+20=70)
