Cost of costruction 1
- draw and calculate the cost of constructions for five structures from the link below
- draw shapes, show calculations
e.g. "2" standing up: "2" sitting down
1G x $1000 = $1000 2G x $1000 = $2000
1R x $750 = $750 2R x $750 = $1500
8W x $500 = $4000 6W x $500 = $3000
Total = $5750 Total = $6500

Starting next week, I will be teaching G9 math to those who are interested to learn before high school.
Most likely to be Day 2 and Day 5, and any G8 students are welcome. Spread the word to those not in my classes.
Need a pencil, eraser, calculator and a positive attitude.

8B, 8C, 8D
- water system test on Monday June 2. Open book, my class notes are very important
- ESL students can get paper test in Chinese, Farsi or Korean
- study. If you don't study, you will do poorly
Trip tomorrow
- arrive at school by 7:15am. It will be rainny and cold in Blue Mountain
- warm clothing (long pants, sweatshirt, extra socks)
- Don't bring a laptop or an iPad. Just your phone and charger
Those who are not going will stay with me (8C, 8D), following 8C schedule
- I will take attendance for the next three days
I will check your Coding assignment 4 on Tuesday. These are some of the options and what I look for
- apples drop from the sky into a box (a metre that counts when an apple drops into the box). Automated
https://www.youtube.com/watch?v=wS1QETPfgGE
or
- spaceship hits asteroids and there is a metre that counts when an asteroid is hit. Automated
https://www.youtube.com/watch?v=sqsNb0s7Oq4
or
- a bird or seagull drops waste on Kwok's head. Every time a dropping falls on my head, the metre will +1. Automated
TDSB summer program for Grade 8 students
-Reach ahead, get a grade 9 credit

You need to complete lesson 4 on the Coding assignment. The video in the blog shows that a spaceship tries to shoot down astroid and there is a number count how many are destroyed.
Kwok's suggestion: Have a bird fly over my head and start to count how many droppings hit my head. This part should be done after the Victoria |Day long weekend , by Tuesday May 20
The number count should be automated when a droppings hit my head.

Now, create a Scratch code to drop apples (or anything you wish) into a box, following the tutorial below

Sample from Angela (8D), codes to animate the character
Coding assignment criteria
I will be checking your Coding assignment tomorrow. Have it ready.
This is what I am looking for
1) Three different backgrounds
2) When a character moves to the edge (top, bottom, left or right), it will hop to another background automatically
3) All the codes that allow you to do this
8B, 8C, 8D (Science test, water system)
- by the third week of May (after Victoria weekend, after May 19), you will have a test on water system
- need to know if you are taking good notes in class (open book test)
- a lot of the materials I cover is not in the textbook (water table, Walkerton, Flint, filtration, river and ocean profiles etc)
- should start studying soon
8C, 8D
- volume and surface area test tomorrow. Bring formula sheet, a calculator and study
8B, 8C, 8D (Science test, water system)
- by the third week of May (after Victoria weekend, after May 19), you will have a test on water system
- need to know if you are taking good notes in class (open book test)
- a lot of the materials I cover is not in textbook (water table, Walkerton, Flint, filteration, river and ocean profiles etc)

8B
- Spawning of salmon in upstream environment
https://www.youtube.com/watch?v=PHKsXQrl41c
https://www.youtube.com/watch?v=aPf4qtCDRtE
Create a program that:
Has a character that can move around (Challenge: Can you animate the character walking?)
When the character moves to the edge, they will be transported to a different area (See gif below). The transportation does not need an animation, or needs to be in a specific room.
Hint: Look at our previous lesson on ‘The Grid’.
Minimum 3 backdrop from place to place (e.g. Amazon rain forest to Great Wall of China and then to Sahara Desert)
- add sound when the character drops in to a water well
Bonus: Can you put sprites in each of the areas to make the places more lively?

3D Geometry (volume, surface area) test on Wednesday May 7. Do the practice test this weekend.
- detailed solutions will be posted on blog this afternoon when I don't have to deal with other non-essential issues
- Make sure you have your Scratch account ready on Monday. No Scratch account, no participation in Daniel's coding lesson
Solution for practice test
- and volume for cylinder should be 11304cm3
3D Geometry math test next week, Wed May 7 (volume and surface area)
- make sure you have a Scratch account by Monday
Grad Hoodies
- order by May 9
- around $45 to $50 each
- cannot order after May 9
- it will shrink after washing/drying, and you are growing
