| Description: |
This problem allows students to investigate ratio and proportion, by discovering the exchange rate between different alien currencies (i.e. 7 circles have the same value as 3 triangles, etc.) By manipulating these exchange rates algebraically, students can come up with equations which represent the money needed to buy certain products. The use of symbols for coin types encourages a symbolic or alphabetic representation of each type of currency. |
