Again the formulation of the task is change one number in the row below to fix the marble slide.
Marble slide exponentials answers.
Then prepare with released staar questions.
Love the success feedback on each slide.
What is the domain of an exponential function f x kb x.
Parabolas desmos just released their newest set of activities on tuesday aptly named marbleslides.
Students who know a little something about domain range and slope intercept form for lines y mx b.
At least 3 in each class knew there were 16 ounces in a pound so multiply the answer by 16 ounces.
Recap exponential functions using a desmos activity.
Great set up in low entry point and working its way up to attainable challenge problem.
H x x 3 2.
Exponentials desmos spiraling practice answers link to answers standards common core hsf le a 2 construct linear and exponential functions including arithmetic and geometric sequences given a graph a description of a relationship or two input output.
The original activities went so well last year that i decided to regularly give more marbleslides challenges throughout the year.
I forced students to work as pairs instead of having them work independently.
G x 15 7 x.
Students will test their ideas by launching the marbles and will have a chance to revise before trying the next challenge.
We also discussed how much 2 26 kilograms was in grams.
Dirtymath live stream episode 2.
The kids loved it.
I wonder why this terminology is not used then.
I wanted to give activities that anyone familiar with graphing lines could complete with some effort but that could also provide further challenge for students who know more about graphing.
I decided to use the last day before christmas vacation to let my algebra 2 students give the parabola challenges a try.
F x 3e 2 x.
G x 2 x 2.
I did marble slides with exponentials in my class.
They had to graph exponentials by hand the night before for homework and struggled so i thought it would be a great opener for the class.
The prior knowledge indicated in the notes mentions y mx b should be known.
I liked how some students knew it would be a power of 10 but weren t sure if there were 100 grams or 1 000 grams in a kilogram.
Of these functions only h x is not an exponential function remember that the independent variable must appear in the exponent for the function to be exponential.
