Ocean explorers or mathematicians research the wreck of the CSS H.L. Hunley. They investigate the actual dimensions of the Hunley using math and measuring skills. Afterward, they sketch a large scale drawing of the submarine outdoors on...

Using a Smart Board, or a plain ol' white board or chalkboard, the teacher pulls up a grid and demonstrates how squares and rectangles can be divided up into equal parts. The class will get their own graph paper to draw shapes and divide...

Students create a work of art based on a theme showing skill in pencil shading. They create a work of art showing value contrast to center of interest. They use math concepts to enlarge a composition using a grid.

Identifying the location of ordered pairs on coordinate planes is the focus in the math instructional activity presented here. In it, 4th graders are introduced to coordinate pairs, the x/y axis, and the techniques associated with this...

Investigate the area and perimeter of polygons in this geometry lesson. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape of...

Learners explore geometry by participating in a school measuring activity. In this perimeter instructional activity, students discuss the techniques and methods used in order to measure a large perimeter or geometric figure. Learners...

Using a twelve foot knotted rope, students form a 3-4-5 right triangle. Following a discussion of observations about the lengths of the sides of the triangle, students use grid paper, scissors and a centimeter ruler to draw and measure...

Seventh graders examine the process of constructing a site plan map at archaeological sites. They discuss the process of mapping techniques and calculation of percentages, create a plan site map of a cellar at Jamestown, and calculate...

Students analyze problem solving techniques for equations with variables by playing a game called "Smackdown". They place variable cards on a grid and use the area model to calculate an answer after spinning a game piece to determine the...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

Third graders are exposed to finding the area of polygons by decomposing figures and recomposing them into rectangles. This strategy allows children to expand on their prior knowledge of constructing shapes by rearranging parts into...

Sixth graders estimate surface area of a pond using a random number table.

Young scholars plot slope fields. In this introduction to slope fields lesson, students plot 12 slope fields for given differential equations.

Students explore how the Pythagorean Theorem works and how to apply it.

Students are introduced to the Pythagorean theorem. They use three different activities that give students the opportuntiy to observe triangles, and use the Pythagorean theorem and practice different ways of determining areas of...

Students discuss square numbers. In this math lesson, students find square numbers and support their answers. Students find sums and products that are square numbers.
