Guess My Slope
Students will estimate the slope of six lines. Students will then return to each line and use the measurement capabilities of the TI-nspire to find the actual slope of each line. Students will find the absolute value of the differences between their estimates and the actual slopes in order to d...https://education.ti.com/en/activity/detail/guess-my-slope
Once and For All...Absolutely
The activity is designed to be a lesson in solving absolute value inequalities. The intent is to distinguish the kinds of solutions that absolute value inequalities have and the forms of stating the solutions. More importantly the activity considers two methods of solutions: a graphing method and...https://education.ti.com/en/activity/detail/once-and-for-all---absolutely
What is a Fraction?
This activity helps students understand and visualize a fraction as a number that can be represented as a point on a number line.https://education.ti.com/en/activity/detail/what-is-a-fraction
Equivalent Fractions
This activity helps students understand that two fractions are equivalent (or equal) if they are located at the same point on the number line. Students recognize that, as with whole numbers, when ordering fractions the larger of two fractions is located farther to the right on the number line.https://education.ti.com/en/activity/detail/equivalent-fractions
Fractions and Unit Squares
This activity is intended to extend the concept of fraction to unit squares, where the unit fraction fraction is a portion of the area of a unit square.https://education.ti.com/en/activity/detail/fractions-and-unit-squares
