CN Outdoor Maths
19 juin 2023In the 7th grade, during mathematics students had the topic: Percentages, Volume and surface of a cube and cuboid, Direct and indirect proportionality, financial mathematics. They were divided into 4 groups and they had to do four tasks. The first was to count how much soil they needed for raided beds, then to count the percentage of the evergreen trees , leafy trees and bushes. After they had to count how much money they needed to buy little stones for fireplace seating and the last task was to count how much time the janitor needs to cut the grass in the school garden. The aim of the lesson was to revise and connect the given topic with interesting tasks from everyday life. The students had to measure the necessary data they needed for the calculation. They had the biggest problem with the last task, where it was necessary to estimate the size of the school garden, which is quite fragmented. For estimation, they mainly used pacing, or approximate measurements of parts of the garden. In the task with woody plants in our garden, some students did not know the difference between a tree and a bush, but they discussed it in the group.
The activity was really interesting and the students managed to work well in groups. although they did the measurements well, the results of the students in the groups were different mainly for the following reasons: - inaccuracy in measuring and counting trees - bad guess (4th task) - different raised beds - two types (task 1) - bad calculation (task 3).
