An unusual game


Tuesday 25 June 2013

Today soccer was a blast, we got to have a whole session playing a massive 4 team game. Ben chose the first two teams to go up first. First it was Red vs Blue, It was so suspenseful like my cat steering down my dinner Seeing if he would get some of it. Next it was yellow vs
Non-Bibs. The first game was won by a tie of 0 - 0, Then the next game was won by a tie
so all in all It was a Perfect tie.

Geometry- finding areas


17th June 2013

WALT find the Area of 2D shapes

Formulae:

Area of a Square = side x side
Example: The area of a square of side  5cm = 5 x 5 = 25 cm2

Find the area of the following squares:

The area of a square of side  10cm =    100cm2
The area of a square of side  25cm =    625cm2
The area of a square of side  5m =        25m2
The area of a square of side  50m =      2,500m2
The area of a square of side  1km =      1km2

Area of a Rectangle = length x width
Example: The area of a rectangle whose length is 6cm and width is 4cm = 6 x 4 = 24 cm2

Find the area of the following rectangles whose lengths and widths are given below:

Rectangle 1 - length is 8cm and width is 5cm
Area = 40cm2

Rectangle 2 - length is 10cm and width is 7cm
Area = 70cm2

Rectangle 3 - length is 8m and width is 6m
Area = 48m2

Rectangle 4 - length is 16m and width is 10m
Area = 160m2

Rectangle 5 - length is 4km and width is 2km
Area = 8km2








Geometry


WALT find the Perimeter of 2D shapes

Formulae:

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 Participated in a class math activity practicing my geometry.

Dear President
Thank you for sponsoring us to have Duffy books.
Reading has improved majorly in our school with all the free books.
It’s an extraordinary deal to get free books for the whole school and not to mention all the learning going on. Please continue to support us as we love reading books even though we have our net books it’s nice to switch over to a nice chapter book.

Thanking you
Yours sincerely
Jerome
