Mental Maths
In term 1 until now we always do Mental Maths for mathematics after we do some hard work. In mental maths there are 109 question of multiplication, division, addition, and subtraction. We always do mental maths because by doing this we can be faster in computation such as multiplication, division, addition, and subtraction. When we do mental maths the time is limited, usually it takes only 5 minutes. After 5 minutes, even though you haven't finished doing all questions you have to stop. You have to check your answers after that.
Tessellation
In mathematics I have been learning about tessellation. Learning about tessellation shows that math has a connection with art. The rule to make Tessellation is no gaps and overlaps. It doesn't matter what shapes it is as long as the shapes will tesselate and the pattern is repeated. If a pattern shows no gaps and overlaps, it means it is a tessellation.
I have made a tessellation by myself. This is how I made my tessellation. First I designed my tessellation using an online Tessellation. I made 4 designs in that website. Then I had to decide which design I wanted to make. After that ,, my teacher Ms. Agnes gave me a piece of 1 cm square grid paper. After that I made that tessellation design using a pencil and some color pencils. Here is my tessellation picture. I hope you like it and can learn how to make your own tessellation.

Science Week
On 6 February 2009, We have a Science Expo. On the morning of 6 February 2009, We make a volcano model experiment, We make the volcano model in 2 hours. After 2 hours we see who is the winner in our class. In our class there is 4 groups, I'm the group 1. Luckily group 1 is the winner. Then our teacher give us our second chance. In the second chance group 1 is not the winner any more, but group 3 is the winner. Even though the second chance group 3 is the winner, I am still happy because I also have a chance to be a winner.
