What makes a good best-fit line? In the 10th part of a 16-part module, scholars learn how to analyze trend lines to choose the best fit, and to write equations for best-fit lines to make predictions.

class members first work through finding the equation, table of values, graph, and key features of a linear function expressed verbally. Individuals then work through several more problems given different representations.

Students use large numbers and learn exponential representation and explain patterns and relations of powers of 2.

Students determine how a counting pattern is created is the story. They estimate how much rice is given to the wise man.

Students recognize and explain a pattern.

Students practice plotting functions on the Cartesian coordinate plane while participating in a discussion about the Possible Or Not worksheet/activity. Students also use the Impossible Graphs worksheet to practice reading a graph,...

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

Students explore the concepts of mean, median, and mode. They develop an understanding and familiarity with these concepts. Students explore mean and median in an efficient way. Students explore three different measures of center.

Young statisticians are introduced to box plots and quartiles. They use an activity and discussion with supplemental exercises to help them explore how data can be graphically represented.

In this quadratic applications worksheet, learners complete graphs, charts, comparison charts, and more having to do with quadratic equations. Students complete 5 different activities.

Ninth graders translate sentences into equations. They translate equations into sentences. They solve real life problems using verbal models to write equations. They create a problem solution graphic organizer in their journals.

Ninth graders develop an understanding of and the applications for linear equations and their graphical displays. They participate in a cooperative learning activity of matching a graphic display with an equation.

Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.

Pupils will explore numbers rules. They will create a picture of their rule and exchange their paper with a classmate. The classmate works to figure out the rule. They then share with each other how they found the rule. Questions are...

Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.

Pupils study Pascal's triangle. They construct their own version of Pascal's triangle, and relate some of the uses for it. While working through this process, students practice their integer multiplication and division skills.

Young scholars perform basic operations in modular (clock) arithmetic. Students encode and decode messages using shift and affine ciphers. Young scholars apply their multiplication, division, addition, and subtraction skills.

Students recognize patterns in a numerical sequence, create new patterns and predict outcomes to established sequences.

Students become "shape detectives" as they identify, name, create and describe common shapes within pictures and objects found within the learning environment. Suggestions include incorporating shapes into all learning areas and daily...

First graders investigate the Commutative Property of Addition. It is introduced using models such as students, counters, balances and dominoes. They discover the order of the numbers in an addition sentence does not change the result...

Learners discover patterns and sequences. They use a website to explore patterns and fractals. Students share their discovery of fractals and their patterns with the class. They develop a list of patterns used in everyday life.

Students are given a set of Old Poly cards and then match polynomials to their factored forms in a game of Old Maid. They complete a worksheet for assessment.

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

Third graders use tables to organize and display related pairs of numbers, such as the relationship of the number of insects to the total number of legs. They generate a table of related number pairs based on a real-life situation,...
