This means that we could write the algorithm: Move one square forward, Move onesquare forward, Fill-in square with color and that would correspond hp officejet pro 8720 keeps tearing up papers while printing to the program: 3 4 Now it s time to get a little more practice. Capture: Write each of the commands down so that students can see all of the steps that went into the one image. Armed with this new method, challenge the class to choose one of the hardest images that they can handle. Better and Better Have your class try making up their own images. How did you feel during todays lesson? Fill In Square with Color, move One Square Down, move One Square Left. Use larger grid paper. Supply each group with several drawing grids. Choose another image and go again! Start your class off in the world of programming by drawing or projecting the provided key onto the board. 6) Write programs for more complex images. An algorithm that has been coded into something that can be run by a machine. Fill in the graph for the class, then ask them to help describe what you ve just done. Have each pair/group choose an image from the worksheet. Fill-in, Step forward, fill-in, step forward, fill-in, step forward, step forward, fill-in, Step forward, fill-in, Step forward, fill-in, next line.

This means that we could write the algorithm: Move one square right, Move one square right, Fill-in square with color and that would correspond to the program: Using arrows, we can redo the code from the previous image much more easily! After doing a few of these, it becomes obvious that an image of this size is pretty hefty. Trade programs with another pair/group and draw one another's image. As you hear an instruction that you intend to follow, make sure to repeat it out loud so that the students can keep track of what you are doing. Do these symbols help the process go more quickly? The classroom may be buzzing with suggestions by this point.
