Equations Lesson Plan
Seventh graders play "What's my Rule" beginning with simple equations and working towards harder problems as student's gain confidence. They evaluate the equations by graphing them. Students identify the slope and y intercepts of the...
Curated OER
Fences and Posts
Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...
Curated OER
Impossible Graphs
Students distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane
Curated OER
Practicing Arithmetic
Pupils practice single operation arithmetic ranging from single digit addition to long division of decimals or real numbers using Graphit. They use data sets and rules to graph ordered pairs.
Curated OER
Introduction to Scatter Plots and Correlation
Students examine the concept of scatter plots. They compare baseball statistics to locate the ones that correlate with winning, and identify the positive, negative, and no correlation in sets of data using MS Excel.
Curated OER
Solving Equations Using Two Operations
Need more detail in showing your class how to solve two-step equations and proportions? This lesson plan outlines the steps young mathematicians need to solve simple equations and check their results. 
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....
Curated OER
My Peanut Butter is Better Than Yours!
Students explore the concept of statistical data. In this statistical data lesson, students read an article about the dangers of peanut butter to those who are allergic. Students perform a taste test of two different brands of peanut...
Curated OER
Inequalities Involving Absolute Value
Students solve and graph inequalities involving absolute value. They discuss and identify the basic properties of inequalities, and solve basic examples.
Curated OER
Graphs and Functions
Students are introduced to plotting functions on the Cartesian coordinate plane seen several categories of functions, including lines and parabolas
Curated OER
Using Representations to Model Problems
student make predictions or draw conclusions based on physical and visual representations of profit and sales. They model problems with physical materials and visual representations, and use models, graphs and tables to draw conclusions...
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.
Curated OER
Counting Pills
Students are introduced to the problem. They brainstorm ideas for approaching the problem and keeping track of what has been done. Students work on the problem in pairs to discover what strategies might help to find the answer.
Curated OER
Flow Rates of Faucets and Rivers
Learners work together to discover the flow rates of faucets and rivers.  They relate their results to engineering and applied science concepts.  They make predictions on the flow rate of a nearby river in their local community.
Curated OER
The Topsy-Turvy Twins
Fourth graders read the problem and brainstorm for ways to solve the problem - list these on the board for the students to refer to as they solve the problem. They work in pairs and focus on the strategy selected.
