TRANSCRIPT
Can you name any objects in the room that are smaller than 1 centimeter?
Why would you use millimeters instead of centimeters to measure?
10 millimetres = 1 centimetre
Draw 1 millimeter on your paper using a ruler… what did you learn about millimeters from doing this?

In our world what would we measure with the
millimetre unit and why is this unit useful?
Millimetres, Centimetres and Metres
Create large shapes on the floor using masking tape.
Measure them by following your lines with string and then measuring the string using a metre stick.
How would this measurement change if you used a different unit of measurement? m? cm? mm? Try each one!
Converting Units
Millimetre (mm) Centimetre (cm) Metre (m)
1 mm 0.1 cm 0.001 m
10 mm 1 cm 0.01 m
100 mm 10 cm 0.1 m
1000 mm 100 cm 1 m

If you change metres to centimetres, willthe numerical value become greater or
less? Why?
Perimeter and Area- Rectangleshttp://www.amathsdictionaryforkids.com/dictionary.html
Perimeter - The area around something◦Perimeter of a rectangle = l + l + w
+ w
Area – the amount of space an object covers◦Area of a rectangle = length x width
Find the PerimeterPerimeter of a rectangle = 2l + 2w or 2 (l +
w) Create as many rectangles as you can with
a perimeter of 20 cm

PIGS ROBERT MUNSCHhttp://robertmunsch.com/book/pigs
Megan is told to feed the pigs, but not to open the gate. She does of course, and the results are hilarious as the pigs help themselves to coffee and the newspaper at the breakfast table, follow Megan to school, and ride home by way of the school bus.
Constructed Response - Area
Complete the constructed response on page 11 of the student booklet
A farmer has 100 m of fencing to make a pen for his pigs. He decides a rectangle would be the best shape.
What are some possible sizes of pens he could make?
How do the areas of the pens compare and what sizethey would recommend and why?
What pen has the greatest area?
What is special about this rectangle?
Find the perimeter and area of a classroom door, then come up with a concept for our “Spring” door.
Draw your door and list all the necessary materials and their measurements.
Write your name at the top and enter it into the teacher inbox to deicide our “Spring has Sprung” door!

measured using cubic centimetres and a 3-D object that would be measured in cubic metres and explain why?
CapacityCapacity is used for measuring
liquids or the containers that hold those liquids
It is measured using millilitres (ml)or litres (L)Order your containers from least to greatest…
What did you notice?
Capacity - Estimation
Mr. Franklin filled a bucket with water to clean his floor. Does the bucket probably hold 9 litres of water or 9 millilitres of water? Explain.

This bottle is1 L of water.
A millilitre is about 20 drops of water.
Capacity - ConversionComplete page 17 of student booklet
To convert from litres (L) to millilitres (ml) you must multiply by 1 000
1 L = 1 000 ml
To convert from millilitres (ml) to litres (L) you must divide by 1 000
1 000 ml = 1 L
