Grade 8
Students in Grade 8 expand their computational fluency and proportional reasoning to include percentages and fractions with unlike denominators. The emphasis is on using ratios & proportions and common geometric formulas for area and volume, as well as solving equations with whole number solutions. Student practice using symbolic logic (algebra) to communicate multi-step problem solving. Visual models include a number line and a cartesian plane with values less than zero, tree and table models of multiplication/factors and visual patterns represented as input/output tables.


In the table below, you will find instructional resources organized by theme as well as according to discrete skills for Grade 8 Math
Note:
Operational Fluency refers to ease of recognition of which operation is required for a given problem and Computational Fluency (the proficient use of various models and strategies to perform the desired operation)
