Teach basic logic using Boolean operators. Young computer scientists learn about the operators NOT, AND, and OR, and how they can be expressed using Boolean notation, logic gates, or truth tables. Along the way, they learn about half...
Curated OER
Nand Gate Logic
Students assess how to construct all possible circuits out of Nand gates. They divide into groups and are given a set of manipulatives to organize and explain the operation of a Nand gate. Each group recognizes the need to construct...
Curated OER
The Absolute Truth
Young scholars solve problems of inequalities and equations. In this algebra lesson, students add, subtract, multiply and divide to solve inequalities. They graph their solutions on a number line.
