You'll C-E-R a difference in classroom achievement after using a helpful lesson. Designed for economics, civics, government, and US history classes, participants practice using the CER model to craft arguments about primary and secondary...

How have educational standards evolved? Educators of adults examine expectations in the 10th workshop out of 15 to better determine how standards have grown. Participants respond to a variety of sample questions to determine how they...

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Ninth graders demonstrate application of area, surface, and volume. They apply formulas to a model of the classroom so they can determine the volume and surface area of the classroom.

Students explore mathematical applications of the current intra-city World Series. After learning how one school district is incorporating the World Series in its classrooms, students consider possible applications of the Series in their...

Students use the disciplines of math and science to examine ecosystems. In groups, they calculate the amount of supplies they would need to live in the classroom for one day, a week and a year. Using this information, they apply it to...

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Students discuss the benefits of the International Space Station. They evaluate the challenges the designers faced when trying to design the space station. Students discuss the use of scale models when designing large structures and...

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

Students explore what happens when geometric figures are transformed on the coordinate plane. They work in pairs, moving geometric shapes in the plane, and formalize their rules as functions.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Students explore what a proof is, how and why mathematicians create them and compose essays on how reason and logic are employed in the workplace. They explore whether any three lines can make a triangle and attempt to verify Goldbach's...

Young scholars 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),...

Students work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....

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.
