Buffon's Needle
Find the needle on a lined paper. Pupils run a simulation of dropping a needle on a lined paper. The probability of the needle crossing at least one line is pi/2. After each trial, the interactive displays the approximation of pi based...

Coin Toss
Are your young mathematicians having a hard time making heads or tails of probabilities? It's no toss up—here is a resource that's sure to straighten them out! Learners run the interactive to toss a coin a different number of times....

Overlapping Gaussians
Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

Spread of Disease
Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...

Two Colors Applet
Find the box with two green balls. The applet uses six balls, three green and three red, and hides them in three boxes. Pupils choose a box and click on it to reveal the color of balls inside. Using the chosen box, the simulation keeps...

Pythagorean Explorer
Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

Skew Distribution
Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness.

Normal Distribution
Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...

Multiple Linear Regression
You'll have no regrets when you use the perfect lesson to teach regression! An interactive resource has individuals manipulate the slope and y-intercept of a line to match a set of data. Learners practice data sets with both positive and...

Possible or Not?
What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

Make your own Antelope Horns!
What are those horns for anyway? Little ones discuss the shape, texture, and purpose of horns found on animals such as the deer and antelope. They then pair up and make their own set of antelope horns to wear while visiting a local...

Fraction Penguin
Exploring mathematics through art is a fun and concrete way to help learners grasp a concept. They will construct a paper penguin using fractions cut from circles. They'll need to determine 1/8, 1/4, and 1/2 of each circle. Once the...
Curated OER
Practice With Commas
The instructions say to put commas where they belong, and that is just what your class will do as they practice comma placement and use. There are 20 sentences in desperate need of commas and four extensions exercises where comma use is...
