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 Using language, symbols and text Thinking Participating and contributing Managing Self Relating to Others
What mathematics will be involved? • Length • Volume & capacity • Weight • Shape • Shorter/longer • Direction of the sun • Temperature • Cost (plants, compost..) • Growth/survival statistics …
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?
Whichgarden 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 Experiences What 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 Sustainability Site 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?
