Slope Notes 8th Grade Pdf.
Students encountered linear relationships with positive rates of change and either positive or negative vertical intercepts. The graphs of these relationships all had an uphill appearance.
English Language Arts. Students learn how to represent, interpret, and analyze functions in various forms, leading to understanding features such as rates of change, initial values, and intervals of increase and decrease. In Unit 4, eighth-grade students are introduced to the concept of a function that relates inputs and outputs.
Slope From A Table Worksheet
After about 4 minutes, I will ask three students to deeply discuss their responses to the Do-Now aloud. I will ask students to share out what they already know about the rate of change, and to recall where we have used it before. Each group will also have white boards and markers to write on in lieu of guided notes. Most of my students are familiar with slope formula from their middle school math classes, so today's lesson aims to further their understanding of this concept, and to show students the connection to the linear functions we have been studying in class.
My students already knew how to calculate the slope between two points, but didn't have a firm understanding of what it meant. I will ask students to decide which Rapper won the first leg of the race. I'll give students time to work independently, using their own mathematical reasoning and to calculate an answer.
After a few minutes, most students came to the conclusion that Jay Z one the first leg of the race because he was able to run at a speed of 1 mile every 8 minutes.
I will illustrate the math used to calculate this answer on the board:. Next, I will write the values in the table as coordinate points. Then I will label the points: x1, y1 x2, y2. Lastly, I will show students that the math that we used to calculate Jay'z's speed was really just the formula for slope, but applied in a different context. Before moving on, I will ask students to write two linear equations that model both Jay-Z and Kanye's speed. We will analyze what each component of the equation represents as a review from our last class.
I will show students this variation of the formula, and discuss the similarities and differences between using f x1 vs y1. By today's class students should be familiar with function notation. After this point, I will only represent the rate of change using f x. Students should also create an equation to model this situation. Discuss whether the slope is positive or negative how this can be verified.
We will spend the next 15 minutes to practice calculating the rate of change through a relay race. Students will form teams, and then stand in lines in the back of the classroom. There will be whiteboards on the other side of the classroom on a desk that is directly across from where each line in standing. When I say "GO! They will hold up their board to me when finished.
When it is correct, they will run back to the other side of the room to tag two more people on their team who will then repeat the process. The pair with the most points at the end of 15 minutes will be the winner. I laminated and cut up the handout and left the cards in a cup at each desk next to the whiteboards Keep the numbers on the cards when you cut them in order to quickly check each problem when students are showing you a response.
I will ask students to turn to a neighbor and to briefly summarize what we learned today in class. I will then ask a few pairs to share out for the group. Empty Layer. Home Professional Learning.

Big Idea Students will interpret the rate of change in the context of a problem, and use it to make predications about a situation that shows linear growth. Lesson Author. Grade Level. Linear and Nonlinear Equations. For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change. For example, in a linear model for a biology experiment, interpret a slope of 1.

Slope Notes 8th Grade Pdf
Slope is a heavily emphasized standard in high school math, but its origins like all math really predate high school by years. In fact, students are already seeing the precursor to slope in 6th grade — rates, unit rates, and graphing an independent and dependent variable on a graph. Today, we are going to explore slope in all of its math glory. Here are a few TEKS to show you some of the vertical alignment of this skill s. It is always more helpful for me to see a test question than a standard, so I pulled a few questions from the STAAR to show the progression of slope from middle school to algebra.
After about 4 minutes, I will ask three students to deeply discuss their responses to the Do-Now aloud.

This Simplifying Algebraic Expressions card sort activity will strengthen your students skills at distributing and combining like terms. Students are given 16 expressions to simplify. They must match each expression to its simplified version. Need a numerical version without variables? Version A does not require distribution while Version B requires distribution.

Беккер старался говорить как можно официальнее: - Дело весьма срочное. Этот человек сломал запястье, у него травма головы. Он был принят сегодня утром. Его карточка должна лежать где-то сверху. Беккер еще больше усилил акцент, но так, чтобы собеседница могла понять, что ему нужно, и говорил слегка сбивчиво, подчеркивая свою крайнюю озабоченность. Люди часто нарушают правила, когда сталкиваются с подобной настойчивостью.
Его смерть бросает на Цифровую крепость тень подозрения. Я хотел внести исправления тихо и спокойно. Изначальный план состоял в том, чтобы сделать это незаметно и позволить Танкадо продать пароль. Сьюзан должна была признать, что прозвучало это довольно убедительно. У Танкадо не было причин подозревать, что код в Интернете не является оригиналом. Никто не имел к нему доступа, кроме него самого и Северной Дакоты.
- Это невозможно. Он перезагрузил монитор, надеясь, что все дело в каком-то мелком сбое. Но, ожив, монитор вновь показал то же. Чатрукьяну вдруг стало холодно. У сотрудников лаборатории систем безопасности была единственная обязанность - поддерживать ТРАНСТЕКСТ в чистоте, следить, чтобы в него не проникли вирусы.
Немец. Какой немец. - Тот, что был в парке. Я рассказал о нем полицейскому.
Иначе Танкадо не отдал бы ключ. Какой идиот станет делать на кольце надпись из произвольных букв. Фонтейн свирепым взглядом заставил его замолчать. - Вы меня слышите? - вмешался Беккер, чувствуя себя неловко.
Хотя и ненамеренно, именно Стратмор привел Дэвида Беккера в АНБ в тот памятный день, позвонив ему по телефону.
Прибыв на место, офицер увидел мертвого Танкадо, рядом с которым находился упомянутый канадец, и тут же по рации вызвал скорую. Когда санитары отвезли тело Танкадо в морг, офицер попытался расспросить канадца о том, что произошло. Единственное, что он понял из его сбивчивого рассказа, - это что перед смертью Танкадо отдал кольцо. - Танкадо отдал кольцо? - скептически отозвалась Сьюзан.
