Rich Mathematical Tasks for Time Poor Teachers
Sue Campbell & Louisa Linterman
Education for Sustainability
And Mathematics
How would you define a mathematically rich task?References:• Neyland• http://nrich.maths.org• Examples• All the ways to make 24• domino sorting• domino environment• domino tetrads
Digging around for a good idea
A parent has donated a 24 metre length of flexible edging for a raised garden.
Now we can create the garden you wanted.
At the heart of the NZC is the learner
• What is the purpose of building a garden?
• What knowledge will they develop?
• Which curriculum areas could you integrate?
• How do you capitalize on those teachable moments?
Key Competencies
Thinking Using language, symbols and text
Managing Self Relating to Others
Participating and
contributing
What mathematics will be involved?
•Length•Volume & capacity•Weight•Shape•Shorter/longer•Direction of the sun•Temperature•Cost (plants, compost..)•Growth/survival statistics …
What shape could the garden be?
What area can the garden be using the 24 metre length of edging?e.g. 6 x 6 = 36m²
10 x 2 = 20 m²
• What is the smallest garden that can be created?
• What is the biggest garden?
Which garden configuration will be best for the plants and the student gardeners?
Thinking & Reflection
• In collaborative groups discuss your designs and come up with your group’s preferred option.
• Present this as a plan to the class (diagram, sand saucer, equipment/blocks)
• Reach a class consensus on the design that is best for the plants, site & the gardeners (question of the day, statistics).
Getting the dirt on….gardens
• How much soil will need to be purchased?• 40 litre compost bags are on sale? If the
compost is spread on at 20cm – what area will a bag cover?
• What depth of soil will be needed for the plants to thrive?
Rich Learning ExperiencesWhat mathematical opportunities did the creation of
a class garden provide?
How can you capitalize on them?
Ideally at the end of the day the students should be exhausted and the teacher as fresh as a daisy!
Education For SustainabilitySite in development• efs - resources & tools
Digital Tools• How does your garden grow?• Explore the soil• Chemical Reactions• The Array• Design Your Own Park• Why recycle?
Other Starters
• Question of the day
e.g. how much plastic do we bring to school for food & drink breaks?
• Estimate the weight
• Compare this to the volume
• What happens to this plastic when we have finished with it?
