This 1 page front/back set of notes is given to the students and is filled out while presenting the PowerPoint HOW THE COMPUTER WORKS that is on sale for $9.99 in my store. This is a good way for students to follow along with the presentation and keep them engaged while presenting information. Purchasing the PowerPoint will give answers to all the blanks. I tell students that filling in all the blanks will give them a 100 and help them study for their quiz (on sale for $4.99)
