V članku je opisan primer dejavnosti, ki je osnovana z namenom, da učenci samostojno, s procesom preiskovanja na različnih stopnjah zahtevnosti oblikujejo specifične zaključke. Primer dejavnosti je namenjen razvijanju gradnikov matematične pismenosti v 7. razredu osnovne šole. Mogoče ga je uporabiti tudi v višjih razredih osnovne šole, ga ustrezno nadgraditi, pri čemer spodbujamo učence, da na različne načine, z drugačnimi metodami, določijo ploščino in obseg drevesnih listov.
Abstract
Exploring Tree Leaf Areas and Perimeters
This article describes an activity designed to help students draw specific conclusions independently through investigation at different levels of complexity. It aims at developing the building blocks of mathematical literacy in the 7th grade of primary school. It can also be used in the upper grades of primary school, building on it as appropriate, encouraging pupils to determine the area and perimeter of tree leaves in different ways and using diverse methods.
