The "Adder" Teaches Digital Logic,
Alternate Bases, AND Cooperation

The Adder circuit uses EduGatesTM to Add Binary Numbers just like a real microprocessor! The adder circuit uses a life-size schematic to guide the students in connecting their gates. Two teams run two separate adders for a fun competition...
     

Before students can add Binary Numbers, they have to learn to count using Binary Numbers. A table of human counting (10's), crab counting (4's), and worm counting (2's) makes it clear and entertaining...
   

Each Adder problem starts with two numbers to add. These are set by students on the "A" and "B" inputs...
       

After the inputs have been set, each student does their job performing the "AND", "OR", or "XOR" function according to the lights at their own inputs. The results trickle through the network until all switches have been set...
       

The students demonstrate teamwork and problem solving as they help each other make the right decisions. In this game the team can only win if each member does their job correctly - a good model for all cooperative endeavors...
     

As each student completes their job they raise their hands until the entire team is done. The first team done gets checked for correctness while the other team continues working on the problem. The competition can be intense...
       

The patented EduGatesTM system helps the instructor quickly pinpoint any mistakes. The instructor halts the winning team and then uses the patented automatic mode to find any errors and give feedback to the students...
   

Students correct any mistakes and the competition continues until both teams have gotten the correct answer. Of course, the first team with the right answer gets the point ... and the celebration ...
   

A typical class will solve dozens of problems during the competition, and the students will rotate jobs after each point to ensure they all get to operate the binary inputs and each type of logic gate. The class is wrapped up with a summary of the activities, and there's always time for teacher consultation to lend continuity with other classroom activities...
