Bonding to the nearest Thousands.
Today I managed to solve a task asking me, bonding to the nearest thousands. It was easy cause I knew forty five bonding to a hundred is fifty five so if four hundred and fifty bonding to a thousand it will be five hundred and fifty.

Perimeter 2D Shapes.
Perimeter of a Square = side + side + side + side or 4 x side
Example: The perimeter of a square of side 5cm = 5 + 5 + 5 + 5 = 20 cm or 4 x 5 = 20 cm
Find the perimeter of the following squares:
The perimeter of a square of side 10cm = 40cm
The perimeter of a square of side 25cm = 100cm
The perimeter of a square of side 5m = 20m
The perimeter of a square of side 50m = 200m
The perimeter of a square of side 1km = 4km
Perimeter of a Rectangle = length + width + length + width or 2 x l + 2 x w
Example: The perimeter of a rectangle whose length is 6cm and width is 4cm = 6 + 4 + 6 + 4 = 20 cm or 2 x 6 + 2 x 4= 12 + 8 = 20 cm
Find the perimeter of the following rectangles whose lengths and widths are given below:
Rectangle 1 - length is 8cm and width is 5cm
Perimeter = 26cm
Rectangle 2 - length is 10cm and width is 7cm
Perimeter = 34cm
Rectangle 3 - length is 8m and width is 6m
Perimeter = 28m
Rectangle 4 - length is 16m and width is 10m
Perimeter = 52m
Rectangle 5 - length is 4km and width is 2km
Perimeter = 12km
Evaluation: Today I learnt to..work out the Perimeter of 2D Shape.........

Study Ladder.
Today it was my first time on Study Ladder and I guess I'm not so bad at Financial Literacy Maths. I had all answers right and I'm proud of myself.

Division Facts
This is the score I got for my 9 division facts. I just learned that if you practice hard you will get a 100% correct . If you know your division you'll know your multiplication too. And if you want to improve your multiplication,division,addition and subtraction go to Mathmagician.
