The following list provides you with the basic 8th grade math concepts that should be attained by the end of the school year. Mastery of the concepts at the previous grade is assumed. Note the skill set is similar to that of the 7th grade. The entry into middle school is often accompanied by a comprehensive review of all math skill students have been expected to learn up to this point.

Numbers

No real new numbers concepts are introduced, but students should be comfortable working with factors, taking square roots, and performing basic arithmetic.

Measurements

  • Use measurement terms appropriately, be able to measure a variety of items at home and at school.
  • Be able to solve more complex problems with measurement estimations an problems using a variety of formulas.
  • Estimate and calculate areas for trapezoids, parallelograms, triangles, prisms circles using the correct formulas.
  • Estimate and calculate volumes for prisms, sketch prisms (rectangular) given the volumes.

Geometry

  • Hypothesize, sketch, identify, sort, classify, construct, measure, and apply a variety of geometric shapes and figures and problems.
  • Sketch and construct a variety of shapes given the dimensions.
  • Create and solve a variety of geometric problems.
  • Analyze and identify shapes that have been rotated, reflected, translated and describe those that are congruent.
  • Determine if shapes/figures will tile a plane (tessellate). Analyze tiling patterns.

Algebra/Patterning

  • Extend, analyze and justify the explanations for patterns and their rules and a more complex level.
  • Be able to write algebraic equations/expressions and write statements to understand simple formulas.
  • Evaluate a variety of simple linear algebraic expressions at a beginning level--- 1 variable and first-degree.
  • Be able to solve and simplify algebraic equations with the 4 operations.
  • Substitute natural numbers for variables when solving algebraic equations.

Probability

  • Design surveys, collect and organize more complex data and identify and explain patterns and trends in data.
  • Construct a variety of graphs and label them appropriately and state the difference between selecting one graph over another.
  • Defend your choices of graphs.
  • Make more accurate predictions.
  • Understand the importance of statistics on decision making and provide real life scenarios.
  • Describe collected data in terms of mean, median and the mode and be able to analyze any bias.
  • Make inferences, predictions and evaluations based on interpretations of data collection results.
  • Be able to predict possible outcomes based on background information.
  • Apply the rules of probability to games of chance and sports.
