Altitude to the Hypotenuse
Can your class solve right triangles and identify the properties common to right triangles? They will investigate and state the relationship between the altitude to the hypotenuse and the two segments of the hypotenuse formed by the...
Curated OER
Polynomial Rollercoaster
Learners relate polynomials to a rollercoaster track as they translate a graph around on a coordinate plane. They differentiate between different forms of algebraic expressions.
Curated OER
Introduction to Conic Sections
Learners slice cones and identify the different conics formed. They then derive the formula to solve problems involving cones. Pull out the TI calculators to visualize the slicing and the different parts and properties created.
Curated OER
Indirectly Direct
Student form and test hyptheses using indirect and direct observation. They launch marbles to determine the shape of a hidden object.
Curated OER
PRE ALGEBRA
Eighth graders find missing angles of triangles, quadrilaterals and angles formed by parallel lines cut by a transversal. They use area formulas to find the area of a figure; find the complement and supplement of a given angle; and know...

The Blue Bottle: An Example of Teacher-Guided Inquiry
Learners observe a demonstration in which a bottle containing a colorless solution is mixed, turns blue, then becomes colorless again. They record observations, form and discuss hypotheses, and draw a conclusion based on the evidence.
Curated OER
Baked Polymer Clay 3D People Portraits
Learners discuss methods of building forms with clay (ball and variations, snake, flat sheets). They draw a stick figure of what their sculpture may look like, including correct figure proportion.
Curated OER
Scene Writing
Eighth graders create an original scene or short one-act play within specified guidelines. Assessment is based upon the performance of student-created scenes during class time. Rubrics for assessment and connection to state standards...
Curated OER
Bowen's Reaction Serives: Magma Differentiation
Students investigate the differentiation of magma to form different minerals present in a rock. By using the model proposed by Bowen, they determine the depth, temperature, and composition of magma. Students explain why some minerals...
Curated OER
Rock and Their Properties: Days 2-4
Students engage in cooperative research projects in order to study about the properties of the three basic rock types and the processes that form them. They plan and develop their products.with the resources for conducting their...
Curated OER
Protesting through Art
Students experience critiquing, analyzing, and comparing different works of art from different eras. They discuss how these works can or can't be considered a form of protest and assess how to evaluate their own judgments and values on...
Curated OER
Perpendicular Bisector of a Line Segment
High Schoolers investigate the perpendicular bisector of a line segment. They use Cabri Jr. to construct the perpendicular bisector of a segment. The dynamics capabilities of Cabri Jr. allow your learners to observe the lengths of the...
Alabama Learning Exchange
A Rockin' Investigation
Young scientists identify the rock cycle. In this earth science activity, students participate in web-based research to understand how sedimentary, metamorphic, and igneous rocks form. As a follow-up, they collect various rocks and...
Curated OER
Hurricanes and Tornadoes (Grade 4-8)
Students investigate the concepts of hurricanes and violent weather conditions. In this violent weather lesson, students access an Internet site and watch a video about how air masses behave, how a tornado forms, how hurricanes form, and...
Curated OER
Polykleitan God or Athlete
Students analyze the Polykleitan God depicted in art and create their own ideal form of sculpture. In this sculpture and art lesson, students read about Greek art of the human form. Students analyze the art of Polykleitos and then create...
Curated OER
Diagonals of Quadrilaterals
Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, students use the TI to create a visual of their shape.
Curated OER
Completing the Square Algebraically
Using TI-Nspire, scholars rewrite quadratic expressions by completing the square. They change the equation into vertex form. By the end of this lesson plan, they should be able to change any quadratic equation into vertex form.
Curated OER
Energy Transformations
Students investigate energy and energy transformations. They compare the various forms of energy, create the circuit and sketch the connections. In addition, they label the circuit to identify areas where energy transformation is present.
Curated OER
Angle Bisectors and Medians of Quadrilaterals
Young scholars investigate the properties of quadrilaterals formed by angle bisectors of a given quadrilateral and quadrilaterals formed by the medians of quadrilaterals. This Cabri Jr. lesson provides opportunity for conjecture and...
Curated OER
Scientific Measurement Exercise
Students measure irregularly shaped bones, once using a variety of measurement methods and tools, and then again using standard conventions and metric tape measures. They explore firsthand that standardizing data collection makes...
Curated OER
Observing Lava Flows
Students examine the difference between fast and slow spreading lava flows. They identify various types of lava flow and determine the factors that cause them to form. Viewing photographs of lava flows, students working in groups,...
Curated OER
Expansion and Reform: Applying the Declaration of Independence
Students conduct inquiries and research-acquiring, organizing, analyzing, interpreting, evaluating, and communicating facts, themes, and general principles operating in American history. They use the Declaration of Independence to...
