Science - Earth Hour Activity

Dear all

I was elated when the prizes (as shown below) were placed on my table So many of you have won yourself a prize for participating in the making of the vehicle for Earth Hour Activity.

Just a quick recap, this was actually your homework back then. We have carried out class discussions on energy conversion based on the vehicle constructed by each of you.

Although we fail to achieve the 100% submission, I am still heartened to see the effort shown by most of you. As for those who did not submit, I hope you will reflect on your action and try harder the next time.

The top 5 designs go to Angelina, Ann Kyee, Zxan, Sebastian and En Xi.

Some of the designs will be displayed in Term 3  and during our School Open House. So, do support your friends.

Math Practice Paper Question


Dear 6B

We have discussed the following question in class and let me explain why the answer $30 is wrong using the following method.


Keith bough 5 times as many toy cars as computer games for his friends. He spent a total of $455.
He spent $65 more on the toy cars than the computer games.
Each toy car cost $11 less than each computer game.
What is the cost of each computer game?


Let Toy cars be x and computer games be y

5x + y = 455
5x = 65 + y
x= y -11

5(y-11) = 65 + y
5y - 55 + 65 + y
5y - y = 65 + 55
4y = 120
y= 30


Explanation

The first sentence is already wrong.

Let toy cars means the number of toy car in this case because the equation formed is 5x + y = 455.
This is incorrect because 5 times of toy cars + number of computer games is not equal to $455.
There is no clue that suggests the total number of toy car and computer games at all.


Let say x refers to the cost of one toy car and y refers to the cost of computer game
then only x=y-11 makes sense.
5x means the cost of one toy car times 5 and to add it to the price of one computer game will never give me 455.
Similarly, 5x =65 + y will not make sense since we do not know how many sets of toy cars and computer games there are.

so remember

The key step to solve this word problem is to make comparison between one unit of computer games and one unit of toy car.
