Understanding Grade Scales and High School Credit
Exploring how percentage grades map to letter grades and determine credit eligibility.
Welcome students! Today we’ll explore how percentage grades convert to letter grades and what it takes to earn high school credit. Emphasize why knowing these thresholds helps you set academic goals.
Lesson Objectives
- Read percentage-to-letter grade scales
- Identify credit-earning thresholds
- Prepare to track your own grades
Read each objective aloud. Ask: Which objective sounds most important to you? Use this to build engagement.
Percentage to Letter Grade Chart
90–100% → A
80–89% → B
70–79% → C
60–69% → D
Below 60% → F
Show the chart and point to each range. Ask: What percent do you need for a B? Encourage students to come up and highlight a range on the board.
Credit-Earning Threshold
High schools typically require a minimum of D (60%) to earn course credit. Below 60% is considered failing and does not count toward credit.
Explain that most high schools require at least a D (60%) to earn credit. Ask: What happens if you score 58%? Clarify that below 60% is failing for credit purposes.
Example Calculation
If your average is 75%:
• Letter grade? _____ (C)
• Earn credit? _____ (Yes)
Guide students through this example. Ask a volunteer: If your average is 75%, what letter grade is that? Then: Do you earn credit? Confirm the answers (C and yes) before moving on.
Reflection & Next Steps
Think about your current grades:
- What letter grades are you earning?
- Are you on track to earn credit?
Discuss with a partner or write down your thoughts.
Invite students to think or jot down their responses. After a brief partner share, distribute the High School Credit Threshold Worksheet for hands-on practice.

Slide Deck
Projecting Grade Goals
Calculate what you need to score on remaining assignments to reach a target average.
Welcome back! Today we’ll learn how to project the scores you need on upcoming work to hit your target grade and earn high school credit.
Lesson Objectives
- Review key grade thresholds (A, B, C, D)
- Learn a formula to project needed scores
- Practice with real examples
Read each objective aloud. Emphasize how this skill helps you set clear, achievable goals.
Grade Projection Formula
Let:
• C = current average (%) on completed work
• W₁ = weight (%) of completed work
• W₂ = weight (%) of remaining work
• T = target overall average (%)
Solve for X (score needed on remaining work):
W₁·C + W₂·X = T·100 → X = (T·100 – W₁·C) ÷ W₂
Show the equation structure. Explain each component: current average, weight completed, weight remaining, and target average.
Example Calculation
You have a 75% average on work worth 60% of your grade (W₁=60).
Two tests remain worth 40% total (W₂=40).
You want an overall 80% (T=80).
Calculation:
0.60×75 + 0.40×X = 0.80×100
45 + 0.40X = 80
0.40X = 35
X = 35 ÷ 0.40 = 87.5%
You need about 88% on each remaining test.
Walk students through each step, pausing to check understanding and show how to plug numbers into the formula.
Your Turn: Practice
Use the Grade Projection Practice Worksheet to calculate needed scores in two scenarios. Be ready to compare answers with a partner.
Introduce the practice worksheet so students apply the formula with guidance.

Instructions: Use the Grade Projection Formula from the Grade Projection Slide Deck to calculate the score you need on remaining assignments to reach the target overall average. Show your work and answer the questions below.
1. Scenario 1
You currently have a 75% average on work worth 60% of your grade. Two tests remain that together count for 40% of your grade. You want an 80% overall average.
a) Write the equation using the formula:
W₁·C + W₂·X = T·100 → _______
b) Solve for X (the score you need on remaining work):
X = ____________%
c) What letter grade does that percentage represent? ________
2. Scenario 2
Your current average is 68% on work that counts for 80% of your grade. One final project counts for 20% of your grade. You want to earn at least a 70% overall average (a C).
a) Write the equation:
W₁·C + W₂·X = T·100 → _______
b) Solve for X:
X = ____________%
c) Based on your answer, will you meet the 70% target? Why or why not?
