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. 

Can you justify that mathematically?  Help learners see the process of solving as using mathematical properties rather than a set of steps to memorize in the fourth module of a nine-part Algebra I series. The module contains six...

Sequences are all about recognizing patterns. A module of 11 lessons builds pupils' understanding of sequences through pattern analysis. The practice connects the analysis to linear and exponential equations. This is the first module in...

A piece of this and a piece of that, add domain restrictions and create a piecewise function. Young scholars explore piecewise functions with and without context. Functions include both linear and quadratic parts. The module is the...

The structure of an expression is a descriptive feature. Learners build a solid understanding of quadratic functions using an analysis of expressions in different forms. The seventh module in a series of nine includes 12 lessons...

Systems of equations and inequalities model contextual situations. A set of 12 lessons build a solid understanding of writing and solving systems of equations and inequalities using a variety of methods. The module is the fifth in a...

It's just not enough to know that something is true. Part of a MVP Geometry unit teaches young mathematicians how to write flow proofs and two-column proofs for conjectures involving lines, angles, and triangles.

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Research the interrelationship between math and science. Search the Internet to discover the history of several branches of mathematics and make text-to-world connections between the concepts covered in each branch with related...

Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...

Examine earthquake intensities and ways to measure an earthquake through the comparison of the Mercalli and Richter scales. After completing the pre-lab worksheet, fourth graders compare high and low intensity quakes by testing...

Learners discover hazards related to volcanoes and predict the effects these hazards have on people and land. As blossoming geologists explore various volcanic eruptions, including the hazards associated with them, they...

In the pre-lab, kindergarteners mimic the movements of the eruption of a volcano and discover various volcanoes around the United States. Then, pupils sort different types of volcanic rocks in the lab before learning how volcanoes grow...

Beginning with a pre-lab, kindergarteners trace the letters in the word earthquake and discuss what happens in an earthquake. The lab portion allows young scientists realize that earthquakes trigger shaking of different intensities...

Young scholars identify and interpret that leaves provide food for new trees and plants. Students cut out leaves and glue them on the appropriate number on included worksheet. Young scholars collect different types of leaves and make...

First graders investigate how seeds are moved and how plants grow.  In this plant growth lesson, 1st graders listen to stories, play a game, and view a PowerPoint about plant growth. Students examine various seeds and recognize how...

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science lesson, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...

Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...

High schoolers discuss what happens to their wastewater. They read about the wastewater treatment process. Students are asked what types of things get flushed down toilets or goes down drains in sinks and showers. They are taught what...

Young scholars study the Earth's climatic system and construct a puzzle that names all of the pieces of the  components involved.  In this Climate lesson, students draw a picture on a puzzle piece depicting a specific...

High schoolers visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food...

Students engage in a lesson about the moon and three different constellations. They conduct research using a variety of resources. The teacher leads the class with demonstrations and discussion groups. The research is also guided using...

Learners hear the story, "The Old Man of the Tree. They review story details and answer a set of questions as a class. Students learn the song, "There is Beauty" then reinact the story, "The Old Man of the Tree," and work in small...
