Unit Plan 30 (Grade 2 Math): Time & Money Applications
Blend schedules, elapsed time on number lines, price lists, and coin combinations to solve real-world mini-projects, using clear models, labels, and estimation to check reasonableness.
Focus: Blend schedules, elapsed time on number lines, price lists, and coin combinations to solve mini-projects.
Grade Level: 2
Subject Area: Mathematics (Measurement & Data • Operations & Algebraic Thinking)
Total Unit Duration: 5 sessions (one week), 45–60 minutes per session
I. Introduction
This week we connect time and money in real-life situations. Students read schedules, represent elapsed time on open number lines, build coin combinations, and solve price-list problems. The week culminates in a mini-project where teams plan and budget for a simple class event.
Essential Questions
- How can an open number line help me find elapsed time?
- How do I make the same amount of money in different coin combinations?
- How can I use estimation to check if my time or money answer is reasonable?
II. Objectives and Standards
Learning Objectives — Students will be able to:
- Read and write times to the nearest five minutes; identify a.m./p.m. and interpret schedules.
- Find elapsed time using open number lines (start/end/elapsed unknown).
- Count coins and bills; make target amounts with different combinations and the fewest coins.
- Solve multi-step price-list problems (total, compare, change) and explain their strategy.
- Model and communicate solutions with equations, number lines, tables, and clear labels/units.
Standards Alignment — CCSS Grade 2 (focus this week)
- 2.MD.7: Tell and write time to the nearest five minutes using analog and digital clocks; a.m./p.m.
- 2.MD.8: Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies using $ and ¢ symbols.
- 2.OA.1: Use addition and subtraction within 100 to solve one- and two-step word problems.
- Mathematical Practices: MP.4 (model with mathematics) featured; MP.1, MP.6, MP.7 supported.
Success Criteria — Student Language
- I can show elapsed time on an open number line and label start, jumps, and end.
- I can make an amount of money with different coin combinations and explain my choice.
- I can solve a price-list problem and use estimation to show my answer is reasonable.
