Surfs Up Activity 

The first sweatshirt is cheaper than the second one because 30% of 60 is 42 and 40% off 72 dollars is 43.20. The first sweatshirt is 1.20 cheaper than the second one.

The second jacket is cheaper because 20% off 96 is 76.80 and 30% of 120 is 84. The second jacket is cheaper by 7.20.

The first jeans is cheaper because 30% of 48 is 33.60 and 45% off 68 is 37.40. The first jeans are cheaper by 3.80.

The second tracksuit is cheaper because 25% off 64 is 48 and 30% of 86 is 60.2. The second tracksuit is cheaper by 22.20.

The least you could spent if you brought one of each clothing item would be 200.40 and the most would be 224.80. You would save 24.40.

I figured it out by figuring out what the percent is as a fractions, timing it by the cost and dividing by the fractions denominator. Then misusing the total from the cost.

Here are all my screenshots 1, 2, 3

The thing I found most challenging was using multiplication and division strategies to estimate and solve problems with fractions, because it was hard to found a strategy that worked.

Describe patterns of reflection, rotation, & translation

Assessment Task

W.A.L.T Describe patterns of reflection, rotation, & translation

Instructions 

1. Draw a 10cm x 10cm square.

2. On the top line make a mark at 3cm and 7cm.

3. On the bottom line make a mark at 3cm and 7cm.

4. On the top line where you made the 7cm mark draw that line down 4cm.

5. On the bottom line where you made a mark at 3cm draw that line up 4cm.

6. On the top line at the 3cm mark draw a line to connect with the line at the 7cm mark

7. On the bottom line at the 7cm mark draw a line to connect with the line at  the 3cm mark 

This is the activity I had to do:

Know square numbers to 100 and the matching square roots.

Maths

WALT......Know square numbers to 100 and the matching square roots.

 For the first activity, I had to say what the number shown was: 3, then I had to say how many times it was shown: 4, so the answer was 3 and 4 squared.

For the second activity, I had to times the number by it's self eg: 1x1=1 so your answer would be 1.

My Student Led Conference

The things I enjoyed most about my SLC were: Sharing learning and achievements with my parents.

What went well and why? Something that went well was that my patents were asking a lot of questions, and it was good because, I used up all of the time.

What were the challenges you faced when preparing and presenting your SLC? When my parents asked a question I didn't know the answer to.

What changes would you make for next time and why? I would share more, because I had heaps of time left.

In Maths we have been learning to use a range of multiplicative strategies when operating with whole numbers.

Here is a link to our online modelling book

The strategies we have been learning are:

- Estimate the reasonableness of large problems like 1 788 – 891. Could 497 be right?

- Use multiplication to solve addition and subtraction problems eg.

  64 – 48 = as (8 x 8) – (6 x 8) = 2 x 8= 16

- Use doubling / halving, trebling/ thirding and adjusting to solve multiplication problems,

 eg.  12 x 50 solved as 4 x 150= 600

- Use an algorithm to solve multiplication problems.

- Solve problems using simple cube numbers .

- Use an algorithm to solve division problems.

Here is a link to my Multiplicative Strategies Assessment which shows that I know why and how I use particular strategies. This doc also has screenshots to show which IXL activities I have completed as part of my learning. My Assessment Task

My next step in my Maths Learning is…… SOLVE PROBLEMS USING SIMPLE CUBE NUMBERS

Maths Blog Post

Maths

WALT: Investigate situations that involve elements of chance/ probability.

SOLO level: Relational because, I can explain how to calculate a range of different elements of probability/ chance.

My next step: Is to sit down with a teacher and discuss a new goal for me.

Maths Prove It

WALT...... Generalise properties of multiplication and division with whole numbers.
Here is a problem.

7 + 4 = 4 + 7

Associative  Commutative  Identity 

I think the answer is commutative.

The correct answer is commutative.

Fill in the missing numbers that makes this number sentence true.

( + 509) + 555 = 345 + ( + 555)

This is associative. CORRECT!!!!!

Lets do one more.

Which equation shows the identity property of addition?

5+1 (1+6) = (5+1) +6 | 4+3 = 3+4 | 9+0=9

I think that the answer is 9+0=9.

The correct answer is 9+0=9.

I have been learning to........Use graphs, tables, and rules to describe linear relationships found in number and spatial patterns.

Q.Tina and Tom are twins. Tina saves and Tom spends. Tom found a $20 note on Sunday evening and spent $2 a day starting on Monday. Coincidentally, Tina started work that Monday and gets $2.50 a day.

How long would it be before Tina has more money than Tom?

Working out.

                       Tina | Tom

Monday               $2.50     $18     

Tuesday               $5          $16

Wednesday          $7.50     $14

Thursday              $9          $12

Friday                  $11.50   $10

A.5

I think I reached extended abstract because I can explain how I got the answer and I understand it clearly now.

How to solve grid problems

My solo level is extended abstract because I can create something that goes on my blog that teaches others

Use rates and ratios
