The Number Of The Week

Maths Week 10 Problem + Compound Shapes

Today in maths, I have been working on my VOLUME knowledge and I learnt how to solve a compound shape problem with 3D shapes and as you scroll through my presentation here... you will be able to see it. Thank you for visiting my blog.

Maths- Volume Week 10

Perimeter Word Problems- Maths

Today for maths this afternoon, Miss Peato told us to make a blog post about what we did for last weeks or this weeks maths questions and here is my one about Perimeter. I have only chosen one question to show my thinking and as you can see here it is. 

Cyber Smart Values-Making Links

Today for maths, Miss Kyla came into our classroom and taught us about how to protect your self from public sites that harms or gives you a virus. Here is a google drawing that I had made a copy of and wrote the things that would help me be protective, learn how to participate and also learnt how to show partnership on an online site.

Measurement Hexagons-Pentagons- Maths

Measurement

For maths this afternoon, Miss Peato gave us a task to finish by the end of the day. Our task is about measurement and as you can see here is my presentation about it. On the 7th slide you will be able to see that our WALT is to convert units of measurement. If you didn't know what WALT stands for... well here it is, We Are Learning To. I hope you enjoy reading through this presentation!

Maths- Assessment Stage 7 and 8 (2)

Addition/Subtraction Stage 7 and 8

Solve the problems below. Try to use the strategy explained in the box above each question. Make sure you show all the steps you use to solve it.

Stage 7: Advanced Multiplicative I can choose appropriately from a broad range of mental strategies to estimate answers and solve addition and subtraction problems involving decimals, integers, and fractions. I can also use multiplication and division to solve addition and subtraction problems with whole numbers.

Stage 7: Advanced Multiplicative I can split decimal numbers in parts to solve addition and subtraction problems. e.g.a)  6.03 – 5.8 = __   as 6.03 – 5 – 0.8 = 1.03 – 0.8 = 0.23 (standard place value partitioning)  or b)2.36 + 1.27 = 2 + 1 = 3,  and .3 + .2 = .5,  and .06 + .07 = .13  So 3 + .5 + .13 = 3.63

1. Shona needs a length of wood for some shelves. Her first shelf needs to be 1.27m long and the second shelf needs to be 1.86m long. How much timber does need altogether?

1.27 + 1.86=3.13

1.0 + 1.0=2.0

0.27 + 0.86=1.13

2.0 + 1.13=3.13

2. She ends up finding 2 lengths of timber that are long enough but will have to cut them to the right length. The first piece is 1.5m. How much does she need to cut off it for the first shelf?

2.0 - 1.5=0.5

2.0-1.0=1.0

2.0-0.5=1.5

1.0-1.5=0.5

Stage 7: Advanced Multiplicative I can solve addition and subtraction problems with decimal numbers by rounding and compensating. e.g.  a) 3.2 + 1.95 = (3.2 - .05) +  (1.95 + .05) = 3.15 + 2 = 5.15 Or b) 4.31 - 2.98 = 4.31 - 3 = 1.31 + .02 = 1.33

3. Dane was 1.46m tall when he last measured himself. He has since grown a further 0.47m. What is is height now?

      1.46 + 0.47=1.93

-0.03                   +0.03

 

      1.43 + 0.50=1.93

4. When Dane was 1.46m tall his little sister was  only 0.98m tall. How much taller was Dane than his sister?

         1.46 - 0.98=0.48

+0.02                      +0.02

         1.48 - 1.0=0.48

Stage 7: Advanced Multiplicative I can solve subtraction problems with decimal numbers by reversing to an addition equation then jumping up tidy numbers on a numberline (reverse and jump) e.g. 6.03 - 5.8 =  5.8 + __ = 6.03 5.8 + 0.2 = 6,  6 + 0.03 = 6.03    .2 + .03 = .23       So 6.03 - 5.8 = 0.23

5. Tiana has a container with 2.75 litres of juice in it. She uses it to fill a smaller container of juice that holds .985 litres. How much juice is left in the larger container?

2.75 - 0.985

0.985 +      = 2.75

0.985 + 0.015=1

1  + 0.75=1.75

0.015 + 0.75=0.765

1 + 0.765=1.765

Stage 7: Stage 7: Advanced Multiplicative I can solve problems involving the addition and subtraction of unlike fractions by finding common denominators and partitioning e.g. ¾  + ⅝  =  (¾  +  2/8) + ⅜ =  (¾ + ¼) + ⅜ = 1 ⅜

6. Allanah has 3/4 of a one pizza left and 5/8 of another.  How much pizza has she got altogether?

3/4 + 5/8=1 3/8

3/4 + 2/8=5/8

5/8 + 3/8=1

3/4 + 1/4=1

1 + 3/8= 1 3/8

  

Stage 7: Advanced Proportional: I can use a range of mental partitioning strategies to estimate answers and solve problems that involve adding and subtracting fractions, including decimals. I am able to combine ratios and proportions with different amounts. The strategies include using partitions of fractions and “ones”, and finding equivalent fractions.

e.g. 2 ¾ - 1 ⅔ = 2 - 1 and ¾ - ⅔ = 1 and 9/12 - 8/12 = 1 1/12  (finding equivalent fractions)

7. Tom knows that for every 20 newspapers he delivers he gets $1.60.  How many papers does he need to deliver to earn $20

20-1.6

40-3.2

60-4.8

80-6.4

100-8.0

120-9.6

140-11.2

160-12.8

180-14.4

200-16.0

220-17.6

240-19.2

250-20

8. Hannah has a cup that hold .275 litres and a container that holds 2.2 litres.  How many cupfuls does she need to fill the container.

2.2 - 0.275=1.925

0.275 +       =2.2

0.275 + 0.725=1

1 + 0.2=1.2

0.725 + 0.2=0.925

1 + 0.925= 1.925
