Analyzing Number Cube Sums
Students extend their understanding of theoretical probability and patterns. They use number cubes, to build awareness that a fraction and its decimal and percent representation on the calculator are "close," but not necessarily equal.https://education.ti.com/en/activity/detail/analyzing-number-cube-sums
Who's in the House
Students construct a model of a house, drawing pictures of the people and pets in the house. Students use skip counting strategies to find possible combinations of people and pets that live in their classmates houses with the help of pictures and TI-10.https://education.ti.com/en/activity/detail/whos-in-the-house
Meet my friend the calculator
This activity/lesson introduces the students to calculators and how to use them to find numbers 1 - 20.https://education.ti.com/en/activity/detail/meet-my-friend-the-calculator
Measurement and Geometry
Students explore the use of manipulatives to conduct simple geometry and measurement activities.https://education.ti.com/en/activity/detail/measurement-and-geometry
Marching Columns
Students investigate constructing arrangements of different numbers of manipulatives into equal groups. They learn to use mathematical language, identify patterns with numbers, recognize the commutative property, and transfer the arrangements made with manipulatives to grid paper.https://education.ti.com/en/activity/detail/marching-columns
Map It!
Students explore map making. Students read a story, identify the locations of different places in the story, decide the distance between each set of places in the story, and create a map with a legend.https://education.ti.com/en/activity/detail/map-it
Mean As A Balance Point
In this lesson, students calculate deviations from the mean, how far each value is above or below the mean. Students also focus on the balance point of a distribution, where the sum of the absolute deviations below the mean is equal to the sum of the absolute deviations above the mean.https://education.ti.com/en/activity/detail/mean-as-a-balance-point-bc
What's the Trig?
Students will be introduced to right triangle trigonometry. They will use the TI-89 and Geometer's Sketchpad to construct a right triangle and calculate sin, cosine, and tangent of various acute angles. (Topic - Right Triangle Trigonometry)https://education.ti.com/en/activity/detail/whats-the-trig
Parallel or Perpendicular-What's Your Inclination?
This activity has students discover the relationship between parallel and perpendicular lines and their slopes. After constructing these objects using CABRI Geometry II for the TI-89, slopes are measured. (Topic - parallel and perpendicular lines)https://education.ti.com/en/activity/detail/parallel-or-perpendicularwhats-your-inclination
Parallelograms - Discovering Their Properties
Students use the TI-89 with CABRI™ Geometry to discover properties of parallelograms. They will construct a figure and use the definition to disvoer the figure is a parallelogram. (Topic - parallelograms)https://education.ti.com/en/activity/detail/parallelograms--discovering-their-properties
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
Set Design
Students will use similarity concepts, and the dimensions of the carvings on Mt. Rushmore to create a proportional representation of the carvings for a stage backdrop.https://education.ti.com/en/activity/detail/set-design
Dividing Notes
Students create an altered musical melody by dividing fractions. They compute the value of notes in terms of fractions and make their sum equal to the time signature.https://education.ti.com/en/activity/detail/dividing-notes
Banquet Meal
Students use proportional reasoning skills to increase a family-size recipe to a banquet-size recipe.https://education.ti.com/en/activity/detail/banquet-meal
Thrift Store Markdowns
Students will calculate a series of discounts using increasing unit fractions.https://education.ti.com/en/activity/detail/thrift-store-markdowns
Going in Circles - Inscribed Angles
This lesson has students discover properties of inscribed angles in a circle. Students use the Geometer's Sketchpad application for the TI-89 to construct a circle and an inscribed angle. (Topic - circles)https://education.ti.com/en/activity/detail/going-in-circles--inscribed-angles
What is a Variable?
In this lesson students evaluate expressions, write expressions that correspond to given situations, and use expressions and formulas to solve problems. Students also examine a product of the form ax for given integer values of a in terms of how the value of the product changes for a one unit cha...https://education.ti.com/en/activity/detail/what-is-a-variable-bc
What is an Equation?
In this lesson students begin by establishing the difference between an expression and an equation. Students then investigate expressions and equations to develop what it means to have a solution to an equation.https://education.ti.com/en/activity/detail/what-is-an-equation-bc
