Study Guide — 8.G.B.8
Apply the Pythagorean Theorem to find the distance between two points…
Use the coordinate plane — plot points, read ordered pairs, and describe movement on a grid.
What this standard means
- Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.
- Apply apply the pythagorean theorem to find the distance between two points… with models and explanation
- Plots points from ordered pairs

How to use the 20 practice sets
| Sets | When to use | | --- | --- | | 1–5 | Intro — explore together, short written items | | 6–10 | Core skills — diagrams and written practice | | 11–15 | Mixed review — explain thinking | | 16–20 | Stretch — word problems and mastery tasks |
Pacing: 10–15 minutes per session.
How to practice
1. Label the x-axis and y-axis before plotting 2. Write ordered pairs as (horizontal, vertical) 3. Start at the origin when counting units
_See printable PDF for diagram._
Common mistakes
- Reversing x and y in an ordered pair
- Counting diagonally instead of along axes
- Forgetting to label the point
Review and practice tests
1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for 8.G.B.8.
