With this project we will improve our skill in problem solving in different contexts.
Since the beginning of civilization, humans had used numbers (and later math) to solve daily problems.
Task 1: Beginnings of math
Activity 1: Read the text and answer the questions.
The idea of number already existed among the first human settlers. They used different signs to represent quantities, measure the passage of time, carry out a record of crops or animals and commercial transactions.
Among the oldest methods of counting are the fingers, small stones or notches in bones or tablets.
- What did early humans use numbers for?
- What did the first humans use for counting?
Activity 2: Solve the problems
Problem 1: Thirty members of a tribe eat thirteen kilos of fruits and grains a day. How much food do they need for a week?
Problem 2: With six sheep we can make ten sweaters. How many sheep do we need to make twenty eight sweaters?
Problem 3: The tribe used a stick to measure. The archeologists found a rock with the following inscription
They also found a stick that is 0,866 meters long. Calculate the perimeter of the temple.
Problem 4: A person that walks at 15 km/h can travel a distance in twenty minutes. At what speed does another person walk if he travels the same distance in thirty minutes?
Problem 5: Two archeologists can dig a tomb in fifteen days. How many days will twelve archeologists take?
