Specific Outcomes
MEASUREMENT
Suggestions for Teaching and Learning
Students will be expected to:
Shape and Space (Measurement)
5SS4 Continued...
Solving problems rooted in real life situations by allowing students
hands-on experience with capacity will help them realize that
1L = 1 000 mL. Centres are useful for facilitating this type of learning.
•
Tell students that Jim has to make a recipe in which he has to use two
litres of orange juice. He only has a 500
mL container to measure
the juice. How could he use the 500 mL container to measure two
litres of orange juice? Explain using numbers, pictures and words.
•
Ask students to draw and label three smaller containers whose
capacity, when added together, would equal one L. Ask them to
explain their choices.
•
Ask
students to choose, from a series of containers (5 mL, 75 mL,
200 mL, etc.), a combination that will create a total capacity of one
litre.
Achievement Indicators:
5SS4.3 Relate mL and L in
problem solving situations.
Aside from familiar referents such as 1 L milk cartons and water bottles,
students should realize that a large base ten cube hollowed out would
have the capacity to hold 1 L.
5SS4.4 Provide a referent for a
litre and explain the choice.
A useful referent for a millilitre would be a unit base ten cube. Since
the millilitre is so small, students should use referents that represent
millilitre units like 5 mL =1 tsp or 15 mL= 1 tbsp. Use a medicine
dropper that shows a 1 mL marking. Talk about
how small babies often
receive medicine in this unit. Also, eye and ear drops are often given in
quantities even less than a millilitre.
5SS4.5 Provide a referent for a
millilitre and explain the choice.
Ask students to bring from home a variety of containers to serve
as referents for exploring the concept of capacity,
Using a series of
different containers, ask students to decide, with justification, whether
each would be better measured in mL or L.
Examples might include
a glass of milk, a container of laundry detergent, etc. Students would
estimate the capacity using the units selected and use a litre container to
check their estimates.
5SS4.6 Determine which capacity
unit is represented by a given
referent.
Review the referents for a cm and a metre and ask students to suggest
a suitable referent for 1 mL. Ask them to explain why it would be
suitable. Students should use their referent to determine the capacity of
a small container.
5SS4.7 Estimate the capacity of
a given container using personal
referents.
