MATHEMATICAL EDUCATION
WITH THE USE OF NATURE ENVIRONMENT
Topic:
Cheerful mathematics in the forest.
Main objective: the use of mathematical knowledge in practical situations
Operational goals:
The student can:
- Measure lengths, compare, count, organize numbers, orient yourself
in space, classify objects;
- Work in a group;
- Evaluate your and your colleagues' work.
Methods:
nature trip, practical exercises, presentation,
Forms: individual, groups.
The course of classes:
1. Determining the rules of work in the field.
Before we go to the forest, we divide students into teams. We assign tasks to each of them. Groups have 15-20 minutes to work on prepared commands. Next, teams present the results of their activities and provide answers to questions asked by other groups.
Necessary materials: sewer measure, wrapping paper, string, A4 photocopies, marking pens, transparent and two-sided adhesive tape, envelopes, bandana.
2. A trip to the forest, implementation of assigned tasks.
Team No. 1
Arrange several paths from various natural materials (eg cones, sticks) and measure their individual lengths and their total length. Write down the data on the sheets, make the necessary measurements using a tailor's measure, string, feet, steps or other measures (eg stick). Calculate the length of your paths. You can also do auxiliary drawings.
Try to prepare a text task for other teams based on your measurements.
Team No. 2
Measure with the help of the sewer measure and hand the perimeter of the cut tree trunk and count the grains visible on it to read its age. Make measurements on a piece of paper and analyze them inside your own group. Consider which way to measure the trunk circumference is more accurate and why?
Team No. 3
Let each of you look for five items related to the forest. Together in the team, think about how you can group them. Use a tape to place them on the
wrapping paper. Also create the right legend for your work by using markers, for example by marking what sets it is.
Team No. 4
Think about how many steps and feet or how much distance each of you has to overcome to go 5 meters, 15 meters, 80 centimeters, 20 steps, 80 feet, etc. Record the results in the tables:
Then make comparisons, for example who made the most or fewest steps at the 10-meter crossing? How many steps did you complete together, measuring a 5-meter-long route? etc. Think about what else you can ask and what to calculate based on the data you obtained during the exercise.
Team 5
Estimate the height of the selected tree, take its shadow.
Take also any stick, measure its length, and then the length of its shadow. Using colored markers, mark the obtained data on the axis.
Team No. 6
Measure the circuit of the clearing where we perform our exercises. Make the necessary calculations. Show results to other teams. Count also how many species of trees and what is around. Make a drawing for your calculations.
Team No. 7
Arrange the path from the natural materials according to the scheme. Measure it. For the other children, bring the fun, let each team choose two group representatives. Their task will be to determine who in a given pair will play the role of a guide and who will overcome the prepared track. The difficulty with this game will be the fact that the guide can only use messages such as: two steps to the right, one step to the left, three steps straight, etc., and a person wandering along the prepared road will have blindfolded eyes. The team that will travel the route in the shortest time and the least risky from the prepared track wins.
3. Joint evaluation of field activities.
