Measures!!

Today on Maths Whizz I learnt how to measure and to complete the activity and move on to the next activity.

Math Whizz!!

Today on Math Whizz I learnt how to do fractions and to answer the questions. I am proud of myself  for trying really hard to solve the problem.

Perimeter of 2D shapes

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 = 4 x 10= 40cm  

The perimeter of a square of side  25cm = 4 x 10= 100cm    

The perimeter of a square of side  5m = 4 x 10= 20m

The perimeter of a square of side  50m = 4 x 10= 200m

The perimeter of a square of side  1km = 4 x 1= 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 find the perimeter of 2D shapes.

This is a Hexagon. It has 6 sides and it has 6 angles.
Octagon   This is a Octagon. It has 8 sides and it has 8 angles.

Math Whizz

What I learnt today was how to use fraction and getting then in the correct order and how to use handing data because there are 2 fruit in each bowl and 1 fruit in the half bowl. The most thing I learnt was the fraction.
