K-12 Teaching and Learning From the UNC School of Education

Important Announcement about Online Courses and LEARN NC.

Important Message about LEARN NC

LEARN NC is evaluating its role in the current online education environment as it relates directly to the mission of UNC-Chapel Hill School of Education (UNC-CH SOE). We plan to look at our ability to facilitate the transmission of the best research coming out of UNC-CH SOE and other campus partners to support classroom teachers across North Carolina. We will begin by evaluating our existing faculty and student involvement with various NC public schools to determine what might be useful to share with you.

Don’t worry! The lesson plans, articles, and textbooks you use and love aren’t going away. They are simply being moved into the new LEARN NC Digital Archive. While we are moving away from a focus on publishing, we know it’s important that educators have access to these kinds of resources. These resources will be preserved on our website for the foreseeable future. That said, we’re directing our resources into our newest efforts, so we won’t be adding to the archive or updating its contents. This means that as the North Carolina Standard Course of Study changes in the future, we won’t be re-aligning resources. Our full-text and tag searches should make it possible for you to find exactly what you need, regardless of standards alignment.

Building a paper bridge: An introduction to problem solving
This activity allows the student to explore problem solving strategies while working with a partner. This activity (building a paper bridge), requires students to question word definition and the application of those definitions. Through problem solving strategies, students discover the need for applying math skills.

Building map-reading skills
In Map skills and higher-order thinking, page 5
Now that we know what students can't do, how do we help them develop the skills to read and interpret maps successfully? You may not be surprised to learn that most of the research and literature on this topic stops short of offering actual suggestions....

Calculating slope of a ramp
In On track learning: Safety through technology and design, page 9
In this lesson, students build a ramp and calculate its slope at different heights. They will also test cars to see how the height of the ramp affects speed.

Coordinate plane artwork
For this lesson students will go to the computer lab and use the General Coordinate Game applet created by the Shodor Foundation to obtain a more specific understanding of the coordinate plane, its parts, and how it can be used to graph points. Afterward, the students will practice using the coordinate plane by drawing a picture on a coordinate plane and then writing out directions (using coordinates) for that picture to be replicated exactly by another student, who will not see the picture but will follow the directions.

Critical thinking in science
This unit of inquiry-based lessons teaches eighth-grade students to utilize and develop critical thinking skills. Students will create testable questions; design and perform experiments; collect, organize, and analyze data; and use these results to decide on the next step in the scientific process.

Cubic expressions: Application to fluid transport systems through Murray’s law
In A mathematical model to describe fluid behavior, page 2
The students will view a schematic image of a leaf and the veins of the plant that circulate fluid throughout the leaf. Using a simplified version of Murray’s law, the students will be able to mathematically model the fluid transport system of some plants and animals.

Dear Tootsie Roll company
The students will measure the surface area and wrapper area of five pieces of candy. Using appropriate formulas and measuring techniques, they will complete information needed for a spreadsheet and database. Students wrap up the lesson by writing a letter to the company with the most wasted paper to explain how the waste affects them as consumers and a suggestion for correcting the problem.

Flipping around pentominoes
The students will use Unifix cubes to create the twelve different pentominoes. The students will join 5 Unifix cubes to make different shapes that will lie flat on a table or level surface. The students will then test for new shapes by flipping, sliding, or turning to create each different pentomino.
