This digital interactive notebook is for students learning how to determine if three side lengths or three angle measures determine a unique triangle, many triangles, or no triangle. There are over 40 slides focused on the Triangle Inequality Theorem, the Triangle Sum Theorem, SSS congruence, and AAA similarity.
The notebook starts with student friendly learning targets aligned with the Common Core State Standards (7.G.2). This is followed by a table of contents to the six sections of the notebook: vocabulary, notes, practices, challenges, resources, and assessment. There are hyperlinks on each page to easily navigate through the notebook.
The notes section includes 4 slides focused on the Triangle Inequality Theorem, the Triangle Sum Theorem, SSS congruence, and AAA similarity. There is also a page to add additional notes if needed.
The practices section includes 9 activities. There are discovery explorations, card sorts, and mystery pictures. Formats include drag and drop, matching, coloring, short answer, and extended response. There is also work space provided on many of the slides.
The challenges section includes 7 more activities that may be used as an enrichment opportunity for students. Many of these tasks incorporate writing and solving multi-step algebraic equations to determine unknown values within triangle side lengths and triangle angle measures.
The vocabulary section includes slides to record vocabulary terms and their definitions.
The resources section includes a slide to link videos and other resources.
The assessment section includes a slide to link warm ups, exit tickets, homework, quizzes, or tests. An exit ticket template is included as an example.
This notebook is editable so that you can customize to meet the needs of your students.
