Then students will use the vases of different shapes and fill them with a set amount of water before each measurement. Students then measure the height of the water in the vase (their y-interc...https://education.ti.com/en/activity/detail/using-vases-to-help-understand-what-graphs-mean
Give Me a Hand or Leaf Me Alone - TI-83
In this activity, students find the surface area of geometric shapes cut from card paper and relate it to its mass. They use this data to find the surface area of irregularly shaped objects.https://education.ti.com/en/activity/detail/give-me-a-hand-or-leaf-me-alone--ti83
A Move in the Right Direction
Students physically provide motion data that is collected by a CBL™ and then graph the data. They determine if they "moved in the right directions" by comparing their graph with those printed in the activity.https://education.ti.com/en/activity/detail/a-move-in-the-right-direction
