I tell them to title the poster and make sure every person in the group writes on the poster. I love the Marble Slides Activities and so do the students. They are told to be creative and display the information in a way that is interesting and pleasing. The bacteria problem talks about what bacteria are and how they can multiply very quickly. where A is the initial amount (or population), r is the rate of decrease and t is the time. Post was not sent - check your email addresses! eval(ez_write_tag([[468,60],'analyzemath_com-medrectangle-4','ezslot_1',340,'0','0'])); a1(t) = A1 e- r1 t :      A1 = 200 (1) Exponential Function Poster Activity: This is my very first exponential function activity that I ever created. You can never put a larger disc on top of a smaller one. I’m excited to share with you my list of 9 Must Do Exponential Function Activities! x(t) = x 0 × (1 + r) t. x(t) is the value at time t. x 0 is the initial value at time t=0. The student of mine that created the football problem was not one of my top students, but because he was the one that thought of the scenario, he was interested and did a great job of completing the task.

Get the Compound Interest Study Here! Exponential decay functions are very … The purpose of this grapher is to deepen the understanding of exponential decay functions by comparing two functions with different parameters. Out of necessity last year, I created a Google Sides version of the lesson above. I learned so much and I found that I was really interested in them. Very fun and engaging! ( Log Out /  Exponential growth/decay formula. This is an online grapher for exponential decay functions of the form . (Not a very creative poster either…ugh!). I supply the poster paper, the markers and the scenario sheets. Students are told that they have inherited some money but to receive it, they must follow some rules. Next, I show them their choices which are: Every situation usually gets chosen. where A is the initial amount (or population), r is the rate of decrease and t is the time. Real-life Examples of Solids of Revolution and Cross-Sections. It would be hard to time these stations and expect students to be completely finished with each task. Sorry, your blog cannot share posts by email. I teach on a block schedule and it takes most students a good 2 class periods to get this packet done. The lesson opener is a bacteria problem. The conversations that I hear are amazing. Basically this lesson is a collaborative activity where the students are given an exponential scenario. Google Slides Exponential Functions Activity. Students learn how to manipulate the equations so that the marbles do just what they want. There are so many interesting exponential function situations! If you have a group of rowdy kids that you don’t want up running around, then let them do their own problem on notebook paper or graph paper. Check out this activity in my store: Exponential Functions Activity, (2) Exponential Function Activity in Google Slides Form. Does anyone know how to change an exponential decay graph into a linear one using excel? Determine whether an exponential function and its associated graph represents growth or decay. This study sparks lots of good conversations and helps the students realize that compounding doesn’t make much difference but time invested does make a difference! The task cards cover recognizing growth and decay from an equation, transformations, key features of graphs, the growth and decay model and compound interest. This is a freebie I’d like to share with you! This is the first thing I start with when I introduce Exponential Functions in Algebra 2. You can change your choices at any time by visiting Your Privacy Controls. I’ve learned to watch out for misconceptions. If you are big into digital resources you will love this. They plot the table and then lots of discussions can take place about decay or even the concept of half-life. This doesn’t sound very exciting except that my whole class was in the same Google Slides all working at the same time. Instead of making posters, the students create the table, graph and equation in Google Slides. I now have this version in my TpT store: Google Slides Exponential Functions Activity. ( Log Out /  Once the posters have been created, it’s time for the Gallery Walk! I created this first lesson more than 10 years ago and have been using it ever since! Students measure a Twizzler and jot down the data in a chart. This activity is the ultimate collaborative and differentiable activity. Half-life is the period of time it takes for a substance undergoing decay to decrease by half. It’s amazing! Getting Ready for the October PSAT Math Portion, Examples of Real-Life Arithmetic Sequences. Find a Tower of Hanoi game on the internet or have the students download an app on their phone. If the decaying quantity, N(t), is the number of discrete elements in a certain set, it is possible to compute the average length of time that an element remains in the set.This is called the mean lifetime (or simply the lifetime), where the exponential time constant, , relates to the decay … I really enjoy them and think they are super fun. There’s a ton of information. Maybe I’ll let one class do the posters and one class do the digital form and compare the two.
