The Rule of Four
In this activity, students will use a variety of features of the TI-84 Plus to represent problem situations. Students will look at problems algebraically, graphically, verbally, and numerically.https://education.ti.com/en/activity/detail/the-rule-of-four
Estimating Square Roots
In this activity, students develop an understanding of the relationship between a number and its square root. They will first recognize perfect squares and order them from least to greatest with other numbers. Then students will estimate the square root of a number using perfect squares.https://education.ti.com/en/activity/detail/estimating-square-roots
Drawing Conclusions
This activity introduces students to the concept of collecting and analyzing data and using conjectures to formulate new questions.https://education.ti.com/en/activity/detail/drawing-conclusions

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
Are There Any Seats Left
This activity allows students to use a simulation to understand why airline companies routinely overbook flights.https://education.ti.com/en/activity/detail/are-there-any-seats-left
Changing Before My Eyes
In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates.https://education.ti.com/en/activity/detail/changing-before-my-eyes
Exploring Platonic Solids
This activity is best at the very beginning of a unit on solids. Students will observe Platonic solids using an interactive website (from the NLVM) projected to the whole class. Students will predict the number of edges, vertices, and faces of the five solids and record their predictions on a Lea...https://education.ti.com/en/activity/detail/exploring-platonic-solids
Exploring Quadratic Data
Students will analyze the vertex form of a parabola and find an approximate fit of a model. They will study the quadratic function (parabola) and its properties by developing quadratic models. They also use translation and dilation to change the general parabola.https://education.ti.com/en/activity/detail/exploring-quadratic-data
