Is it possible to use the broken calculator in this Subtangent activity to make a given set of numbers?
There are six levels of difficulty in this activity starting with whole numbers, then introducing negative numbers and decimals.
The broken keys vary at each level giving the opportunity to use the memory function and power keys, which will challenge students’ knowledge of square numbers.
A worksheet, which could be used as an introduction, accompanies this game. Students are required to show how they would use each calculator to generate the numbers from one to twenty.
