Here are two Mimio lessons covering input/output machines and graphs. The graphs lesson covers graphing and mean/median/mode. There are nine slides on the input/output machine lesson and six slides on the graphing lesson. In the input/output machine lesson, students complete the machines with the rule and missing numbers. The graphing lesson has students manipulating the bars of a bar graph to match it to the chart and completing the mean/median/mode charts. These are perfect for STAAR prep.
