Week of November 23-25

In 3rd grade, we learned how to use the substitution method to solve equations that go together.  Although we were tempted to use guess and check for some of the more difficult problems, by the end of class, we realized that we never had to guess when using the substitution method.  Here is a link to some practice problems using substitution:

In 4th grade, we learned how to move objects using the medium motor, and some groups added a color sensor and programmed the robot to stop at a black line.

The 5th graders learned about piecewise functions and conditionals which will allow their players to move in different ways depending on what key is pressed. Our games are almost complete!!!
