It's all about lines when going around. Pupils graph the relationship between the length of a side of a square and its perimeter. Class members explain the origin in context of the side length and perimeter. They compare the graph to the...

Every year, the moon moves 3.8 cm farther from Earth. In the 11th part of 22, classes use the distance formula. They determine the distance to the moon based upon given data and then graph Galileo spacecraft data to determine its movement.

Transform your scholars into mathematicians as they develop their own geometric definition. The task asks individuals to compare cylindrical objects and create a definition for the disc-ness of each object. They may use any method and...

Develop a new measure of the properties of an object. Scholars develop a definition and formula to measure the bumpy-ness of an object. They utilize their formulas to find the property for several spherical objects.

Machines can be so helpful sometimes. A simple interactive has learners enter input values for a function machine and observe output values. These values help determine a function that represents the input-output relationship in the...

Should matrices be allowed to commute when they are being multiplied? Learners analyze this question to determine if the commutative property applies to matrices. They connect their exploration to transformations, vectors, and complex...

Investigate associations between variables with two-way tables. Scholars continue their study of two-way tables and categorical variables in the 15th installment of a 21-part module. The lesson challenges them to calculate relative...

Analyze functions by decomposing complex functions and composing simple functions. Through a detailed lesson plan, pupils learn the vocabulary and notation related to the composition of functions. Practice includes both evaluating and...

Students are introduced to the basic ideas needed for understanding linear functions.

Students explore the concept of functions. In this function instructional activity, students determine if the graph is a function by using the vertical line test. Students use an applet to explore the vertical line test on a variety of...

Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.

Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Students explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their ciphers...

Students investigate modular arithmetic and how to use it to solve real world problems. In this modular arithmetic lesson, students use computers to work on modular arithmetic after a teacher guided lesson. They complete guided practice...

Students investigate patterns in the Food Pyramid.  In this patterns in the Food Pyramid activity, students sort food into different food groups.  Students make patterns with food from different food groups.  Students...

Eighth graders extend skills for representing and solving linear equations to linear inequalities. Lesson activities build understanding and skill by plotting ordered pairs of numbers that either satisfy or do not satisfy a given...

Students explore arithmetic and numerical patterns. After observing a teacher created function box, students describe a pattern and predict what will "come out" of the function box. They explore patterns such as geometric shapes,...

Students practice their patterning skills using national symbols.

Sixth graders need to see the relevance in the mathematics they learn. This lesson builds on the concepts of least common multiple and greatest common factor. The lesson presents real-world problem situations for students to solve.

Students investigate water usage, water available, and water demand historically in the local area. They use projections of water usage, availability and demand up to the year 2050. Students use graphs to relate as well as compare and...

Students explore and examine the increases and/or decreases for water user groups: irrigation, municipal, manufacturing, steam electric power generation cooling, livestock, and mining. They utilize percentage changes during their...

Fifth graders explore and examine how to make organized lists and find patterns to help them solve problems. They identify, analyze and determine a rule for predicting and extending numerical patterns involving operations of whole...

Students identify, extend and create patterns using various types of manipulatives and then work a pattern game in the computer lab to reinforce what was learned.

Students explore the concept of multiplication by using pizza. They read an article discussing how math is used everyday. They try to determine how many pizzas they would need to feed the class.
