I did marble slides with exponentials in my class.
Marble slide exponentials answers.
Then prepare with released staar questions.
We also discussed how much 2 26 kilograms was in grams.
In this delightful and challenging activity students will transform exponential functions so that the marbles go through the stars.
The kids loved it.
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.
F x 3e 2 x.
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.
Parabolas activity builder by desmos.
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.
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.
I decided to use the last day before christmas vacation to let my algebra 2 students give the parabola challenges a try.
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.
Love the success feedback on each slide.
H x x 3 2.
Students will test their ideas by launching the marbles and will have a chance to revise before trying the next challenge.

I forced students to work as pairs instead of having them work independently.
The prior knowledge indicated in the notes mentions y mx b should be known.
Which of the following are exponential functions.
The original activities went so well last year that i decided to regularly give more marbleslides challenges throughout the year.
Great set up in low entry point and working its way up to attainable challenge problem.
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.
