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.

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...

Seventh graders view a recent transparency of the average rainfall zones of the state of Texas. Using another transparency, they identify the Piney Woods subregion of the Gulf Coastal Plain and locate national forests and sawmills. ...

n a class discussion Students identify events or situations as being likely to occur or unlikely to occur. Then, they work in pairs to generate likely and unlikely statements to share with the class.

Second graders review coins and their values. In this coin recognition lesson, 2nd graders review the coin values as they read 'Smart' by Shel Silverstein. Students use class computer demonstrations to identify the coin's names, worth,...

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 review graphing and use processing skills to solve problems.

Learners examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

Students gain an understanding of Kepler's 2nd law--that planets (and satellites) move fastest at their closest approach to the center of attraction, and slow down when far away. They explore the concepts of "potential energy" and...

First graders explore measurement in relation to size of objects.

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Students engage in a lesson which involves role-play and the use of manipulatives to solve subtraction problems. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain subtraction practice. They get to eat the...

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.

Third graders view and measure common body parts to find a fathom, a span, and inch. They discuss the historical information about how standard English measurements came to be and why body parts can no longer be used as a standard...

Third graders are introduced to statistical vocabulary. They complete an online activity that asks them to calculate the mean, median and mode for a set of data.

Students experiment with scale to solve a problem presented in a video clip. They determine the correct size to use when constructing a model and evaluate the use of proportions in real life applications.

Sixth graders record the weight of themselves and 3 family over a week, and then use that data to compile 2 bar graphs and 4 line graphs and answer a series of questions.

Learners calculate the ratio of the height of the body to the height of the navel. They discover that the ratios are all approximately equal.

Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.

Young scholars examine different "cycles" that are found in nature, such as the water cycle and recycling. They create their own artwork about cycles to be displayed on a bulletin board

Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.

Fourth graders review their prior knowledge on the concept of pi. Using broken pieces of pottery, they calculate the circumference from a section of the circle. In teams, they compete against one another to get the most accurate...

Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...
