A seventh-grade math game covering proportional relationships, constants of proportionality, tables, graphs, equations, and percent applications. This is a Grades 7–8 Math review game in a Jeopardy-style format: a teacher puts the board on one screen, teams pick clues by point value, and the class answers out loud — no student devices or accounts needed. Categories: Proportional or Not, Constant of Proportionality, Tables, Graphs, Percents.
- Grades 7–8 Math review
- Whole-class review on one shared screen
- Test or quiz prep
- Team-vs-team practice in class

Board content
Proportional or Not
- $100 — A table where y/x is always 4 represents this kind of relationship.
- a proportional relationship
- $200 — If y = 3x, the relationship between x and y is this.
- proportional
- $300 — If y = 3x + 2, this relationship is not proportional because it does not pass through this point.
- the origin
- $400 — A graph of a proportional relationship is a straight line through this.
- (0,0)
- $500 — If the ratio y/x changes from row to row, the relationship is this.
- not proportional
Constant of Proportionality
- $100 — In y = 7x, this is the constant of proportionality.
- 7
- $200 — If 4 notebooks cost $10, the constant cost per notebook is this.
- $2.50
- $300 — A car travels 150 miles in 3 hours at constant speed. The constant is this.
- 50 miles per hour
- $400 — If y/x = 1.2 for every pair, k equals this.
- 1.2
- $500 — A graph rises 18 units for every 6 units right. Its constant of proportionality is this.
- 3
Tables
- $100 — x: 2,4,6 and y: 10,20,30. What equation relates y and x?
- y = 5x
- $200 — x: 3,6,9 and y: 2,4,6. What is y/x?
- 2/3 — Tables
- $300 — If a proportional table has x=8, y=28, then when x=12, y is this.
- 42 — Tables
- $400 — At $4.50 per ticket, 7 tickets cost this.
- $31.50
- $500 — A recipe uses 3 cups water for 2 cups rice. For 8 cups rice, water is this.
- 12 cups water
Graphs
- $100 — A steeper proportional line generally represents a larger value of this.
- the constant of proportionality
- $200 — A proportional graph must include this point.
- the origin — Graphs
- $300 — On a distance-time graph, slope represents this.
- speed
- $400 — If one line has slope 5 and another slope 2, the first grows this much faster per x-unit.
- 3 more y-units per x
- $500 — A line through (0,0) and (4,12) has this constant of proportionality.
- 3 per x-unit
Percents
- $100 — 15% of 80 is this.
- 12 — Percents
- $200 — A $50 item discounted 20% costs this.
- $40
- $300 — A $60 bill with a 15% tip has this tip amount.
- $9 tip
- $400 — Increasing 200 by 8% gives this.
- 216
- $500 — A price rises from $40 to $50. The percent increase is this.
- 25% increase
