Organization: North Carolina Standard Course of Study Grade Band: 6th grade Standard Goal: The learner will select and use appropriate tools to measure two- and three-dimensional figures.
| Angles |
Lesson: Introduces students to acute, obtuse, and right angles as well as relationships between angles formed by parallel lines crossed by a transversal.
| | Area |
Lesson: Comparing shapes with the same areas but different perimeters.
| | Estimation |
Lesson: Introduces students to making estimations.
| | Length, Perimeter, and Area |
Lesson: Introduces students to length, perimeter and area.
| | Probability and Geometry |
Lesson: Students learn about how probability can be represented using geometry.
| | Pythagorean Theorem |
Lesson: Students learn how the Pythagorean Theorem works and how to apply it.
|  Comparison Estimator |
Activity: Compare two sets of objects, using estimation to determine which is greater. Estimate a number of objects, the length of a line, or the area of a shape. Parameter: error tolerance. Comparison Estimator is one of the Interactivate assessment explorers.
|  Estimator |
Activity: Practice estimation skills by determining the number of objects, the length of a line, or the area of a shape. Parameters: error tolerance. Estimator is one of the Interactivate assessment explorers.
|  Measures |
Activity: Enter data and view the mean, median, variance, and standard deviation of the data set. Parameters: Number of observations, range for observations, which statistics to view, identifiers for the data.
|  More or Less Estimator |
Activity: Practice estimation skills by determining whether the number of objects, the length of a line, or the area of a shape is more or less than the number given. Parameters: error tolerance. More or Less Estimator is one of the Interactivate assessment explorers.
|  Pythagorean Explorer |
Activity: Calculate the length of one side of an automatically generated right triangle by using the Pythagorean Theorem, and then check your answers. Pythagorean Explorer is one of the Interactivate assessment explorers.
|  Shape Builder |
Activity: This activity operates in one of two modes: auto draw and create shape mode, allowing you to explore relationships between area and perimeter. Shape Builder is one of the Interactivate assessment explorers.
|  Squaring the Triangle |
Activity: Learn about how the Pythagorean Theorem works through investigating the standard geometric proof. Parameters: Sizes of the legs of the triangle.
|  Triangle Explorer |
Activity: Calculate the area of a triangle drawn on a grid. Learn about areas of triangles and about the Cartesian coordinate system. Triangle Explorer is one of the Interactivate assessment explorers.
