To work on Eighth grade geometry and measurement standards, click on the standard numbers below to visit pages with internet resources for each of the learning standards.

Checks for Understanding are at the top of this page. Scroll down to find internet resources related to the State Performance Indicators (SPIs).

Checks for Understanding (Formative/Summative Assessment)

0806.4.1	Pythagorean Theorem - Model the Pythagorean Theorem.
0806.4.2	Pythagorean Theorem Converse - Use the converse of the Pythagorean Theorem to determine if a triangle is a right triangle.
0806.4.3	Measurement Instrument - Select or use the appropriate measurement instrument to determine or create a given length, area, volume, angle, weight, or mass.
0806.4.4	Precision and Accuracy - Understand how the precision of measurement influences accuracy of quantities derived from these measurements.
0806.4.5	Congruent and Supplementary - Analyze the congruent and supplementary relationships of angles formed by parallel lines and transversals (such as alternate interior, alternate exterior, corresponding, and adjacent).
0806.4.6	Make Conversions - Make within-system and between-system conversions of derived quantities including distance, temperature, and money.
0806.4.7	3-Dimensional Figure - Visualize or describe the cross-section resulting from the intersection of a plane with a 3-dimensional figure.
0806.4.8	2-D and 3-Dimensional Figure - Build, draw, and work with 2- and 3-dimensional figures by means of orthogonal views, projective views, and/or nets.
State Performance Indicators
SPI 0806.4.1	Use the Pythagorean Theorem - Use the Pythagorean Theorem to solve contextual problems.
SPI 0806.4.2	Find Distance - Apply the Pythagorean theorem to find distances between points in the coordinate plane to measure lengths and analyze polygons and polyhedra.
SPI 0806.4.3	Transversal Cut - Find measures of the angles formed by parallel lines cut by a transversal.
SPI 0806.4.4	Convert - Convert between and within the U.S. Customary System and the metric system.
SPI 0806.4.5	Geometric Figures - Identify the intersection of two or more geometric figures in the plane.
