Several subjects are addressed within the context of a science instructional activity about the sun's ultraviolet rays. Elementary earth scientists consider protection of the skin with sunscreens (health), estimating and measuring...

Eighth graders calculate surface area of 3-D shapes. In this geometry lesson, 8th graders analyze cubes and prisms by finding their area and surface area. They compare the data of these two shapes.

Sixth graders discover what circumference is.  In this measurement lesson, 6th graders identify the radius and diameter of different circles. Students discover how to find the area of a circle using the radius and diameter.

Learners calculate the surface area and volume of shapes. In this geometry lesson, students create different scales and calculate the volume and area for each shape. They compare and contrast between the different scales and shapes.

Students measure an area given a yardstick. They also convert inches into a fractions of a foot and use data to create a linear graph.

Students examine school yearbooks from 1950 to the present. They count the number of male and female teachers and administrators. They compile date and extrapolate changes in job trends.

Inject fun into your math review! Pupils review basic math operations with decimals as well as addition and subtraction with simple fractions. In this number operations lesson, students work in groups to create a game for the math skill...

Take your kids on a tour of graphing rational functions. Using this TI activity, high schoolers identify the end behavior of their functions. They find the domain and range, describe end behavior, and look at asymptotes and restrictions...
