In Week 3 of Cantamaths We had another survey of 2008 Year 8 Questions, which were slightly hard than the Year 7 Questions. As same as always there were very hard questions but there were also very easy questions like "There are 560 students and 26 teachers at our school. We have 2 buses available, one carries 40 people and one carries 28 people. If the buses travel together in convoy, how many trips to the Town Hall will they need to make to get all students and teachers there?" (The answer is 9 by the way). There also was a hard one that asked you how many times the digit 2 appeared in a list from 1 to 300. The leadership trait that I showed was Goal Focused because the question that asked how many times did digit 2 appear in a list from 1 to 300, I wrote a list of the numbers but I still got the question wrong.
WALT: Combine simple proportions to work out what parts the whole is made up in a unit We learnt how to calculate percentage increase and decrease. If you want to calculate percentage increase, you have to find the percentage difference between the two numbers you are comparing and divide the difference by the original number and then times it by 100 and convert that decimal into a percentage. For example: What is the percent of decrease of 16 to 14? The way you would solve this is find the difference between the original number and the new one. 16 - 14 = 2. Divide 2 by 16 which equals 0.125. Multiply that by 100 and it equals 12.5%, So its a 12.5% decrease. WALT: Combine proportions to work out what parts are whole is made up of using non multiples of 10. We learnt how to calculate how much the percentage increased or decreased in number. The way I did this was I found the percentage and if it was an increase: added it onto the 100, and if it was a decrease: subtra...
