Proportional Flag
Students will use the concepts of similarity to create a scale drawing of the national flag, that is large enough to cover most of a football field.https://education.ti.com/en/activity/detail/proportional-flag
What's the Spin?
Students discover properties of rotations using the TI-89 and CABRI Geometry II by rotating a triangle around a point and through a specified angle. They will discover the definition of a rotation. (Topic -- Rotations and their relation to reflect)https://education.ti.com/en/activity/detail/whats-the-spin
Fractions and Skittles
Students will predict how many of each color will be in one pack of skittles before they open the package.
