Conics & Parametrics 1
This activity is a LearningCheck™ to quickly assess students' ability to identify conics from their equations in both rectangular and parametric form.https://education.ti.com/en/activity/detail/conics--parametrics-1
What is an Exponent?
Why are exponents useful and how do they behave? An exponent indicates how many times the base to which it refers is a factor; i.e., in , the 4 indicates that the base, 3, is used as a factor four times. This lesson focuses on how the definition can be used in a variety of situations to make sens...https://education.ti.com/en/activity/detail/what-is-an-exponent--bc
Equations and Operations
In this lesson students investigate the relationship between the solution to an equation and the solution to a new equation formed by adding, subtracting, multiplying, or dividing one or both sides of the original equation by a numerical value. Students develop an understanding of “solution...https://education.ti.com/en/activity/detail/equations-and-operations-bc
Fast nines and Fast tens
Students learn how to solve a mathematical equation with a missing addend. Students will learn the combinations of addends to find the sums of nine and ten. Students practice math facts with accuracy and immediacy for sums of nine and ten.https://education.ti.com/en/activity/detail/fast-nines-and-fast-tens
Can Pythagoras Swim?
Students will investigate relationships between sides of right triangles to understand the Pythagorean theorem and then use it to solve problems. Students will simplify expressions using radicals and exponents in this activity.https://education.ti.com/en/activity/detail/can-pythagoras-swim
The Best Cell Phone Plan
Students will compare two cell phone plans and determine which plan is better for a specific situation. They will utilize both tables and graphs to make their decisions. For this activity, students need prior experience writing linear models.https://education.ti.com/en/activity/detail/the-best-cell-phone-plan_1
In Round Numbers
Students will develop and test rules for rounding whole numbers and decimal fractions. They will use the information to solve real-world problems.https://education.ti.com/en/activity/detail/in-round-numbers
Prehistoric Parabola Match
This activity center is used as a formative assessment after a full unit on the different transformations of vertical parabolas.https://education.ti.com/en/activity/detail/prehistoric-parabola-match
Absolute Values
Students will review the set of integers along with the addition and subtraction of integers using a number line. Then, they will learn that the absolute value of a number is defined as the distance from zero. Students will learn how to interpret the absolute value symbol algebraically, as well a...https://education.ti.com/en/activity/detail/absolute-values
Ready, Set... Solve!
