This 8th grade Math parent guide explains the content in straightforward terms so they can support their children’s learning at home and will encourage caretaker engagement with lessons.
Our Teacher Guides are meant to support the use of our online course and unit content. Please use these to accompany the use of our content and for ideas to support struggling learners, those needing extension and for additional resources.
In this lesson, students practice applying the Pythagorean Theorem to find lengths of right triangles in two dimensions.
This document provides sample performance tasks/assessment items for Common Core State Standards Grade 8 Math provided by the Louisiana Department of Eduation. Both questions and exemplary responses are included.
This task is for instruction purposes. Part (b) is subtle and the solution presented here uses a "dynamic" view of triangles with two side lengths fixed. This helps pave the way toward what students will see later in trigonometry but some guidance will likely be needed in order to get students started on this path.
For this lesson, students explain a proof of the converse of the Pythagorean Theorem. Students apply the theorem and its converse to solve problems.
Introduction to the Pythagorean Theorem through reading a story about the boy Pythagoras. This lesson was developed by Michael Tinker as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.
Discussion about how the Pythagorean Theorem works and what it does for us. This lesson was developed by Michael Tinker as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.
Students will learn about translations, reflections, and rotations in the plane and, more importantly, how to use them to precisely define the concept of congruence.
Students will learn about dilation and similarity and apply that knowledge to a proof of the Pythagorean Theorem based on the Angle-Angle criterion for similar triangles.
This lesson will explores why is c2 = a2 + b2. The students will watch a dynamic, geometric "proof without words" of the Pythagorean Theorem, and then will be asked to explain the proof.
For this lesson, students know that the Pythagorean Theorem can be interpreted as a statement about the areas of similar geometric figures constructed on the sides of a right triangle. Students explain a proof of the Pythagorean Theorem.
This lesson unit is intended to help teachers assess how well students are able to: use the area of right triangles to deduce the areas of other shapes; use dissection methods for finding areas; organize an investigation systematically and collect data; deduce a generalizable method for finding lengths and areas (The Pythagorean Theorem.)
In this unit students will:-Understand Pythagorean Theorem-Use Converse of Pythagorean Theorem to prove if a triangle is a right triange-Use Pythagorean Theorem to find distance between two points on a coordinate plane-Use Pythagorean Theorem to solve real world problem situations
In this lesson, students will know the Pythagorean theorem and be shown an informal proof of the theorem. Students will use the Pythagorean theorem to find the length of the hypotenuse of a right triangle.
