ORIENTEERING AMONG MATHEMATICAL FORMULAS

An Orienteering lesson in Mathematics

Using the map below, and mathematical formulas, answer a number of questions regarding:

• Area

• Perimeter

• Volume • Mass

• Scale

• Per cent

Checkpoint 1

1a What is the sandbox’s area of the football field’s area in percentage?

1b If the height of sand in the sandbox is 15 cm, how much is the weight of the sand?

Checkpoint 2

2a   What is the sandbox’s area? How many times larger is this area compared to the sandbox in Question 1a?

2b   If the height of sand in the sandbox is 15 cm, how much is the weight of the sand?

Checkpoint 3

3a If the spiral staircases were a cylinder, how large would the volume in each cylinder be, and what would the total volume be of all the cylinders in the area?”

3b If these ”cylinders” were filled with water, how much would these cylinders weigh altogether?

Checkpoint 4

4a If the stone wall were one meter high, how much would the whole stone wall weigh from A to B?

4b How long would you draw this piece of stone if you draw a map with the scale of 1:500 and 1:2 500?
