Using the concept of a candy vending machine, young mathematicians explore the sugar ratios found in different types of candy. Using the provided information, class members calculate and compare different ratios in...

Knowing the standard algorithm opens up a whole new world of division. Scholars learn how to convert division involving decimals to division involving whole numbers to use the standard algorithm. Knowing how to multiply with powers of...

Individuals learn to apply the Euclidean algorithm to find the greatest common factor of two numbers. Additionally, the lesson plan connects greatest common factor to the largest square that can be drawn in a rectangle.

Give me more details. Scholars complete an end of unit assessment by creating an information text box to go with their field journal entries about howler monkeys. Learners use the class time to work independently.

Get young people thinking about their lives and current topics of social justice, advocacy, gender, race, and identity. After examining several works by Barbara Kruger, participants select a tag with one of the questions printed on it,...

Learners take on the roles of jurors in a civil case to evaluate evidence and determine a verdict in this engaging online interactive experience.

The brother-sister pair Carlos and Clarita need your class's help in developing their new pet sitting business. Through a variety of scenarios and concerns presented to the siblings, the learners thoroughly explore systems of equations...

What information can come from a box? Learners choose a data set to display as a box plot and decide whether to include the median in the calculation of the quartiles, show the outliers, and change the scale. To finish the lesson,...

Spin into a dicey experiment. Pupils use a spinner or a pair of dice to determine the experimental probabilities of each outcome. The interactive allows for either, one, five, or ten consecutive experiments. Using the applet, learners...

Pupils roll a die to figure out which car advances on a race track. They determine the rules for each car moving forward and, given the statistics of the winner, compare if it matches their predictions.

Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

What are the benefits and risks of saving in an interest-bearing account? Pupils explore concepts like risk-reward relationship and the rule of 72, as well as practice calculating compound interest, developing important personal...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

The matrix — it's not just a movie. The lesson introduces the concept of 2 x 2 matrix multiplication as a way to represent linear transformations. Class members determine when a linear transformation represented as matrix...

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

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. 

President Ronald Reagan's "Tear Down This Wall" speech, delivered on June 12, 1987 before the Berlin Wall, provides class members with an opportunity to examine three key aspects of informational text: author bias, the use of facts and...

Build unity in the dojo or the gym with an activity that not only teaches the importance of stretching and flexibility but also offers class members an opportunity to get to know one another. After warming up and engaging in a Medicine...

Here is a real-world application for systems of equations. When is it better to pay an enrollment fee and lower daily rate, and when is it better to pay the regular price? The local swim center is having a special offer, reductions in...

Did the image I drew match the image you saw? By simulating a satellite and a ground station, teams of two transmit data in the form of pixels in order to recreate an image. They use four different levels of brightness, creating slightly...

Build tables by understanding their structure. Scholars take a closer look at the structure of ratio tables in the 10th segment in a 29-part series. Individuals realize that the tables can be built using an additive or...

Find a way to work with rates. The 23rd part in a 29-part series presents work problems for the class to solve given work rates. Pupils compare rates to determine which is faster. Some problems require learners to convert the rates to...
