Grade 8 Milestones Math practice questions with answers

These three original examples come from TestByState’s Grade 8 practice generator. Read them without an account. They illustrate selected skills, not a complete test blueprint or official released questions.

Example 1

Skill reference: 8.PAR.4

One proportional relationship has equation y = 2x. Another has y = 35 when x = 5. Which has the greater unit rate?

  1. The relationships have equal unit rates.
  2. Relationship B has the greater unit rate.
  3. There is not enough information to compare them.
  4. Relationship A has the greater unit rate.
Show answer and explanation

Answer: Relationship B has the greater unit rate.

Relationship B has the greater unit rate.

  1. Relationship A has unit rate 2. Relationship B has unit rate 35 ÷ 5 = 7.
  2. Relationship B has the greater unit rate.

Example 2

Skill reference: 8.NR.2

Find (2 × 10⁶)(2 × 10³). Write the answer in scientific notation.

  1. 5 × 10⁹
  2. 4 × 10⁹
  3. 4 × 10¹⁰
  4. 4 × 10⁸
Show answer and explanation

Answer: 4 × 10⁹

The product is already normalized: 4 × 10⁹.

  1. Multiply coefficients: 2 × 2 = 4. Add exponents: 6 + 3 = 9.
  2. The product is already normalized: 4 × 10⁹.

Example 3

Skill reference: 8.FGR.6

In y = 3x + 4, x is practice hours and y is the predicted score increase in points. How should the slope 3 be interpreted?

  1. The model predicts exactly 4 hours.
  2. Each additional hour is associated with an increase of 3 points.
  3. Each additional hour is associated with a decrease of 3 points.
  4. The initial value is 3 points.
Show answer and explanation

Answer: Each additional hour is associated with an increase of 3 points.

Each additional hour is associated with an increase of 3 points.

  1. The slope is the predicted change in y for a one-unit increase in x.
  2. Each additional hour is associated with an increase of 3 points.

Grade 8 timing and tools

Georgia publishes a statewide administration window and districts choose local dates. A verified 2027 statewide window was not available when this guide was reviewed, so families should use school communications for exact dates.

Scientific/graphing calculator capabilities are modeled in both sections; Georgia publishes a Grade 8 formula sheet.
