Learners investigate graphing a line. In this algebra lesson, students collect data on the path of a skateboarder. They collect how fast the board is traveling along a straight line and graph their results.

Students relate polynomials to real life situations. In this algebra lesson, students graph equations through modeling and data collection. They must be comfortable doing word problems.

Fifth graders add fractions. After a class discussion on real life application of fractions, the teacher uses fractions strips to model adding fractions. In pairs, 5th graders model adding fractions by drawing diagrams. They justify...

Students experiment and analyze triangulation to assess degrees of combined angles, predict polygons that tessellate as well as extending of shapes to create tessellations. They explore the concept of why some polygons tessellate when...

Pupils work in groups to research clocks and practice telling time. In this telling time instructional activity, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles...

Students investigate the concept of tessellations and how they are formed using angles. They categorize how different patterns do and not tessellate and separate them into two different places for assessment. The teacher draws examples...

Pupils identify how we use water everyday. They determine the amount of water used in different activities. They finally explain why the water supply is limited and how we can conserve water.

How well can a wolf survive without a pack? Third graders read about headstrong Will and his desire to be an independent wolf with a short story and series of comprehension questions.

Scholars show what they know about data collection and analysis with an activity that examines a smaller population of Houghton, Texas. Independently or in pairs, learners identify their research question, gather, graph, and analyze...

Students solve the problem that comes up in the story. They realize the explosive growth of the powers of 2.

Students explore probability through cooperative group activities and interactive video technique.

Students are involved in hands-on activities to determine how course conditions affect bobsled, luge, and downhill ski races.

Third graders perform jobs in order to sustain their classroom community. After completing a brief overview of how local economies are sustained, they complete job applications for classroom jobs. Students perform their jobs throughout...

Tenth graders investigate the Pythagorean Theorem. Then they type up a formal paragraph proof of a proof of their choice.

Students describe the effects of over-harvest on a salmon population. They explain the importance of salmon to many communities in Alaska. They manage harvest levels to maintain a sustainable population.

Students review the productives resources used to produce goods and services and explore how decisions are made in a market economy through the interactions of both the buyers and the sellers.

First graders read about making graphs and lean how to make graphs using "The Graph Club" software.

Students describe the mark/recapture method used to estimate fish populations. They explain the importance of being able to predict population numbers.

Students practice forward and backward counting.  In this counting lesson, students calculate how many objects in a bag by counting forward and then count backward to check.

Students set up a classroom currency exchange and explore the idea of bartering to get what they want. They create a monetary unit that is based on fractions and multiples of a standard unit, and compare this system to the U.S. monetary...

Fifth graders utilize strategies to solve a variety of problems and create problems of their own. They write explanations of problem solutions and using a checklist, evaluate themselves.

Students solve joining problems by using cat counters, pictures, and numbers. First, students listen to the story "Pretend You're a Cat" by Jean Marzollo.

Fourth graders are introduced and experiment with the concept of pi. Using this information, they discover the relationship between the circumference and diameter of circles. In groups, they practice measuring the circumference of...

In this finding right angles worksheet, students look around the classroom and draw any right angles they see. Students then "tick" any right angle in 6 geometric shapes.
