Third graders, in groups, dissect a variety of brands of chocolate chip cookies and calculate the mean for each brand. They create their own bar graphs, pictographs, and line graphs to represent information.

Students examine the concepts of balanced forces, unbalanced forces, and resulting net forces. They participate in a force and motion demonstration by pushing students in various directions, and calculating and identifying the resulting...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

Students calculate angle measure for triangles and complementary/supplementary angles. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice.

Young scholars observe and solve examples of corresponding angle postulates, alternate interior angle theorems, and exterior and consecutive angles. They complete the Determining Angle Measure With Parallel Lines worksheet.

Students observe and solve examples of equations involving radicals. They complete a Doing Battle With Radical Equations worksheet and checklist.

Students observe and solve examples of betweenness, ruler postulate, and segment addition postulate. They complete the Finding the Measure of Segments worksheet using the distance formula.

Students solve uniform motion problems using formula d = rt.

Students observe and solve examples of the complementary angle theorem. They complete the How Do You Pay a Complement to an Angle worksheet, and write a response in their math journal.

High schoolers practice solving quadratic equations using a form called Complete the Square.

High schoolers view examples of a ray, opposite rays, collinear rays, angles, and straight angles. They discuss and demonstrate how to use a protractor and complete worksheet problems on rays and angles.

Students define and discuss congruency and the corresponding parts between congruent triangles. They create a pair of congruent triangles, test for congruency, and complete a worksheet.

Students define and discuss acceleration and how to compute acceleration. They observe examples of computing acceleration, and complete a worksheet using the correct formula.

High schoolers are given standard elemental nutrients, identify plant nutrient requirements based on criteria outlined in assessment instructment. They, are given standard elemental nutrients, provide all means and chemical symbols of...

Second graders study digits in 2- or 3-digit whole numbers. They write and solve story problems which involve whole numbers, using addition, subtraction, multiplication, or division.

Students utilize number sense applications to multiply two digit numbers. They use "The Multiplier" and Internet source to partition and solve 2 digit by 1 digit multiplications. Students describe how to solve 2-digit by 1-digit...

Learners observe and discuss cloud cover. They identify percent of cloud cover, calculate cloud cover by fraction and convert to a percent, and compare their models with the current real sky cloud cover.

Students explore mathematical problem solving. Given a case problem, students write a rule to solve problems involving decimal multiplication and division. They invent problems, share them with the class, and solve other student's...

Students design and build a snowplow using LEGO materials. They compete in an Engineer's Challenge to clear a path through Styrofoam peanuts.

Fourth graders using the idea of "how many more squirts" fill a container to develop multiplicative thinking. They also investigate the idea of conservation of volume when working with oddly shaped containers. They attempt to use...

Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

Students, through lecture and guided practice, discover the properties of similar triangles. They use given measurements of one triangle to find a missing measurement of a similar triangle. They apply this knowledge in real-life...

Students explore expected value, are introduced to the concept of varying payoffs, and have used a computer simulation of a "real world" example where expected value is used

Fourth graders participate in a parachute math game. They run under the parachute after it has been lifted, looking for a card that has an equivalent fraction or decimal on it to match the one they were given by the teacher.
