Properties of Parallelograms
In this activity, students go through the process of proving a quadrilateral to be a parallelogram. They understand the various characteristics of a parallelogram.https://education.ti.com/en/activity/detail/properties-of-parallelograms_5
Properties of Parallelograms
Students will use Cabri Jr. to construct a parallelogram. They discover three properties of parallelograms in this activity: opposite sides are congruent, opposites angles are congruent, and diagonals bisect each other.https://education.ti.com/en/activity/detail/properties-of-parallelograms_6
Exponential Growth Experiment
Students will work in pairs and will conduct a growth experiment. They will record their answers for 7 to 10 trials. They will make a scatterplot of their data and share their graphs with the class.https://education.ti.com/en/activity/detail/exponential-growth-experiment
Exploring Exponential Decay
Students will work in pairs and conduct an experiment with M&M's where they start with a cupful and continue to decrease the n umber of M&M's in their cup.https://education.ti.com/en/activity/detail/exploring-exponential-decay
Estimating and Finding Confidence Intervals
In this activity, students estimate statistical measures and find confidence intervals.https://education.ti.com/en/activity/detail/estimating-and-finding-confidence-intervals
