The Old Chicken Run Problem
Sixth graders apply problem solving strategies to work with a real life situation in which they need to determine the area. They determine the area of chicken runs that are rectangular in shape when give a partial perimeter.
Curated OER
Time Problems
Students make sensible estimates and check for reasonable results. They also solve problems with positive and negative integers using practical activities or models as needed.
Curated OER
Letter Patterns
Second graders look at the number patterns we get from letters and numbers. They keep track of the numbers involved by drawing up a table of values. It's important here to look for the pattern and see how the number of tiles changes from...
Curated OER
Calculating Range for a Constant Velocity
Students read an explanation from the NASA Web-based "textbook", The Beginner's Guide to Aerodynamics, then use the information in combination with data from other Web sites to solve single variable equations for distance (range), time,...
Curated OER
Points
Students listen to Gill's story and determine how many number points she has. They then find the number of points their own name has and get into groups where all the name points are the same.
Curated OER
Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.
Curated OER
Are You Absolutely Sure of the Value?
Seventh graders develop an examineing of absolute value through real world situations. They develop an examineing of when absolute value can be used in a given situation.
Curated OER
Learning by Sorting
Students sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.
Curated OER
Equation of State Problem Set
Students demonstrate their understanding of the equation of state by computing the gas constant from air properties. They use online research tools and apply integrated math problem-solving strategies to solve problems outside the realm...
Curated OER
Where in the World?
Students explore how GPS works, the mathematics behind the technology, and how GPS is used. They find positions in one and two dimensions, and participate in a WebQuest that explores how math is used to find a location on Earth using GPS.
Curated OER
Calculating & Graphing Using a Spreadsheet
Students use the lab apparatus to calculate the average velocity and average acceleration at several points and record the data. They use the spreadsheets to plot distance vs. time, velocity vs. time and acceleration vs. time graphs.
Curated OER
Make Your Own "Weather" Map
High schoolers create their own "weather" map using data from x-ray sources. They analyze and discuss why it is important to organize data in a fashion in which is easy to read. They compare and contrast different x-ray sources using a...
Curated OER
Polygonal Strings
Sixth graders apply knowledge of how to calculate the area and perimeter of triangles. They determine why it is inappropriate to measure the area of land by its perimeter which is done in certain areas of New Guinea. They complete a...
Curated OER
Glow With the Flow
Students investigate the force of drag and how NASA engineers use models and glowing paints to examine how air flows over vehicles in a wind tunnel. They discover how the blended wing body will affect air travelers of the future.
Curated OER
Graphs
Students graph ordered pairs to model the relationship between numbers. After observing the patterns in ordered pairs, they describe the relationship, and create graphs from a data table. Students describe intervals in the graph, and...
Curated OER
Matrix operations and Matrix Inverses
Eleventh graders study how to combine like vector's that are matrices. In this matrix operations worksheet, 11th graders combine matrices linearly and define the matrix-matrix product and its properties. Students also study matrix...
Pennsylvania Department of Education
Creating Polygons
Students describe, make and compare polygons. In this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
3-D Beginning Graphs
Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.
Curated OER
Cannot Buy Me Love
Students investigate the concepts that are related to finance and how it is used in the world. They take part in activities that are focused around the use of a spreadsheet while using a T-chart to simulate a ledger of credits and debits.
Curated OER
Math Training Module: Using the Internet in Support of GED Math Instruction, Session One: Overview
Students brainstorm about math they do every day, and explore relevant web sites to find definitions of "numeracy." They then explain relevance of the definitions of numeracy to their own instructional practices.
Curated OER
The Truth About Triangles and Squares
Fourth graders investigate the patterns associated with both triangular and square numbers. They use counters as manipulatives to depict the numbers as needed but focus on problem solving using mental math techniques.
Curated OER
Shaking Hands
Students use diagrams or lists to show relationships. They also identify the pattern of triangular numbers. The mathematics behind situations provide a way of problem solving to examine the answers.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson plan and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
Graphing With RXTE
Students use data from the Rossi X-ray Tiiming Explorer (RXTE) satellite to analyze and graph.
