Perimeter is the sum of the distance around the shape. The units of measurement used are millimeters (mm), centimeters (cm), meters (m) and kilometers (km).
Maths Maintenance
Before we start our Maths we always do our Maths maintenance. This time we were in pairs practising our times tables. Each had to take turn asking for example, "What is 8 times 4?". After two minutes the bell was rung and they had to move on to another station which had a different times table strategy. We did this for 10 minutes which means we used a variety of ways to multiply.
Lucy and Joseph were using the playing cards.
Connor and Iuvale made use of the numbers on a fan shape.
Ijaz and Ciaran were focusing using the flash cards.
Kiana and Tim were doing the same.
Cortia and Scott worked out a multiplication strategy.
It was Samantha's turn to ask Nicholas.
Michelle helped Lennon and Savannah with their times tables.
Molly and Benzo rolled the small dice to find the product of two numbers.
Lexi and Bradley used the big dice.
PERIMETER
To find the perimeter each pair was given an empty box of grocery items such as a box of tea, crackers, washing powder, cereals, etc.
We traced the shape of the box of grocery item on the paper. Next we measured the shape of the box of grocery items using a ruler.
Molly and Benzo were deciding how long is one side of the box of crumbed fish.
The sides of the shape were measured in centimeters. Scott and Cortia were trying to find out how many centimeters are there on the width of the box of crackers.
Savannah and Lennon were watching Michelle adding the sides of their shape.
Ciaran and Ijaz added the length of the four sides of the box of the
washing powder.
Lucy and Joseph measured 62 square centimeters around the sides of a box of tissues.
Connor was finding out how to convert centimeters to meters.
Tim and Kiana measured their box of soup. They converted 52 square centimeters to 0.52 metres and then to 0.052 kilometres.
To convert the units of measurement we have to remember:
Small to big----DIVIDE (SBD)
Big to small----MULTIPLY (BSM)
10 mm = 1 cm 100 cm =1 m 1000 m = 1 km
We found it easy to find the perimeter of shapes. We have to be careful when converting the units of measurement.
