Tentative 8th Grade Math Standards Goals
Kelly Aaron, Leslie McGowan, Suzette Stephens
2nd Nine Weeks
Students will be able to…
• use properties of congruent figures to solve problems 8.G.2-reasoning
• transform plane figures using translations, rotations, and reflections 8.G.1reasoning, 8.G.2-reasoning, 8.G.3-reasoning
• determine whether figures are similar and find missing dimensions in
similar figures 8.G.4-reasoning
• identify and create dilations of plane figures 8.G.3-reasoning, 8.G.4-reasoning
• identify parallel and perpendicular lines and the angles formed by a transversal
8.G.5-reasoning
• find unknown angles and identify possible side lengths in triangles 8.G.5reasoning
• identify transformations as similarity or congruence transformations 8.G.1reasoning, 8.G.3-reasoning
• identify the image of a figure after a combined transformation is performed and
determine if the final image is similar or congruent to the original 8.G.3reasoning
• find square and cube roots 8.EE.2-knowledge
• estimate square roots to a given number of decimal places and solve problems
using square roots 8.NS.2-knowledge
• use the Pythagorean Theorem to solve problems 8.G.7-reasoning, 8.G.6knowledge
• use the Distance Formula and the Pythagorean Theorem and its converse to solve
problems 8.G.8-reasoning
• know the formulas for the volumes of cones, cylinders, and spheres and use them
to solve real-world and mathematical problems 8.G.9-reasoning
* subject to change per teacher discretion
