Four lessons spotlight a variety of professions while boosting listening and observational skills and making inferences. Lesson one challenges pupils to group cards based on a commonality then justify the relationship they see....

Build right angles using coordinate geometry! Pupils explore the concept of slope related to perpendicular lines by examining 90-degree rotations of right triangles. Learners determine the slope of the hypotenuse becomes the opposite...

While creating models from data, pupils make decisions about precision. Exercises are provided that require linear, quadratic, or exponential models based upon the desired precision. 

Class members make a real connection to matrices in the 25th part of a series of 32 by looking at the identity matrix and making the connection to the multiplicative identity in the real numbers. Pupils explore different...

How many points are needed to define a unique parabola? Individuals work with data to answer this question. Ultimately, they determine the quadratic model when given three points. The concept is applied to data from a dropped...

Building on knowledge from the previous lesson, the second lesson in this unit teaches scholars to identify and interpret rate of change and initial value of a linear function in context. They investigate how slope expresses the...

Pupils work several real-world problems that use percents in the 11th portion of a 20-part series. The problems contain percents involved with taxes, commissions, discounts, tips, fees, and interest. Scholars use the equations formed for...

Make all the ratio representations fit together. The 15th segment in a series of 29 presents ratio problems to solve. Scholars use a variety of representations to respond to the questions. The problem set has pupils show how the...

Even or not, here I come. Groups investigate the parity of products and sums of whole numbers in the 17th lesson in a series of 21. Using dots to represent numbers, they develop a pattern for the products of two even numbers; two odd...

What happens when combining percentage discounts? The last lesson in a series of 29 introduces the idea of combining discounts one after another. Pupils wrestle with the claim that to find the total discount, they need to only add...

Take any number, multiply it by five, and then divide by five. Did you end up with the original number? In the same vein as the previous lesson, pupils discover the relationship between multiplication and division. They develop the...

Students explore the concept of probability. In this probability lesson, students develop an understanding of probability by pulling marbles out of a bag and recording the data. Students use the recording sheet to discuss the results of...

Students investigate the concept of succession and plant community dynamics. They play a game in order to conduct multiple experiments while playing. The interest of the game is useful for keeping student interest throughout the activity.

Middle schoolers apply properties of probability to the real world. For this probability lesson, learners simulate the construction of empirical distribution. They collect and analyze data using central tendencies.

In this reading skills worksheet, students read about skills to use while reading and then fill out a Venn Diagram. Students choose which items to go into their Venn Diagram.

Students observe which of ten types of clouds are visible and how much of the sky is cloud covered. They see that by observing clouds, we can get information about temperature, moisture, and wind conditions in different places in the...

By examining a set of dice roll data, statisticians determine the probability of different sums occurring. They visit an interactive website and determine how many different vacation outfits Bobbie Bear will have based on the colored...

By reading two books aloud, Ben and Becky in the Haunted House and The Ghost in the Classroom, youngsters learn new words and understand story events. They workin small groups to review the vocabulary in a game-like setting. 

Students use NASA satellite data to see cloud cover over Africa.  For this seasons lesson students access data and import it into Excel. 

Class members discover how mathematics can quantify the behavior of light waves with the fourth installment of a seven-part series that teaches future engineers about equations related to refraction, including the equation to...

Students observe and count bird sightings around their schoolyard throughout the school year.

Students examine how gas pressure causes eruptions of explosive volcanoes, and demonstrate how the build-up of gas from dissolving alka seltzer causes the lid of a film canister to blow off. They compare/contrast between the model and...
