1. Sweatshirt- The surf shop sweatshirt is cheaper because you take 30% off and it’s cheaper than the other sweatshirt.
2. Sweatshirt- The surf shop sweatshirt is $18 because you take 30% off and the other sweatshirt is $28 because you take 40% off, so the sweatshirt is $10 cheaper.

1. Jacket- Surf the waves shop jacket is cheaper because even though it has a lower percent it is still cheaper.
2. Jacket- The surf shop Jacket is $36 because you take away 30% the second jacket is  $19 because you take 20% off so the second jacket is $6 cheaper.

The thing that I found most challenging was using percentages to solve the equation.

Some strategies we did:
12 ÷ 3 =1 2/3
. Find a fraction of another fraction by multiply.
. Describe and show remaining tenths, hundredths and thousandths as decimals fractions and relate them to replace value order.

Find and validate data measures e.g. MEAN, MEDIAN, MODE & RANGE from appropriate displays

W.A.L.T : Find and validate data measures e.g. MEAN, MEDIAN, MODE & RANGE from appropriate displays

Here is an example:
3, 6, 4, 3, 9, 2

The range is 7 because you take the largest number ad the smallest and minus it, the range is the answer

Find and validate data measures e.g. Mean, median, mode and range from appropriate displays

I can describe what mean, median, mode and range mean.

Mean: Add all the numbers together and then divide it by how many numbers there are e.g.  23+25+28+31+37+41=185 then 185 divide it by 6= 30.8

Median: Get all your numbers from smallest to largest then get the one in the middle and that's your answer. If there are two numbers in the middle then plus them together then divide the answer by two

Mode: The answer is the number that is shown most e.g. 3,6,4,8,3,6,2,2,3,3 the answer is 3 because it is shown most

Range: Get the largest number and the smallest number minus them and the answer is your answer
