This exercise trains students to identify problems in which a given algorithm can lead from a given input to a desired output.

Calculating an Averages Array from Two Arrays – C#

This activity deals with solving a problem in stages. The solution begins with analyzing the different characteristics of the problem and possible ways to solve it, and ends with a neatly written main procedure.

Using the Circles Model for Adding Signed Numbers

In this activity, students practice adding signed numbers using the “circles model.” In this model, signed numbers are represented visually.

Exponents – Is It Possible?

In this activity, questions are presented in the context of exponents, in which students must determine whether certain relationships between the value of a power and its base are possible.
