Grade 2 · Proportional & Applied Math
Money: Coins and Bills
Learn to use arithmetic to solve money situations through clear explanations, worked examples, an interactive model, and guided practice.
Lesson coverage
Learn the whole topic, not just one problem type.
This lesson and its practice bank deliberately rotate across these core facets so students build a connected understanding of the subject.
Recognize and combine money amounts.
Add prices accurately.
Subtract to find money returned or remaining.
Compare cost per item or unit.
Use money math in buying and budgeting situations.
Build the idea
Money: Coins and Bills is part of the build fluency with place value and operations while introducing money, measurement, graphs, arrays, and equal groups. Start by identifying what each quantity, symbol, diagram, or graph represents before calculating.
Coin & bill values
Recognize and combine money amounts. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Totals
Add prices accurately. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Change
Subtract to find money returned or remaining. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Unit price
Compare cost per item or unit. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Applications
Use money math in buying and budgeting situations. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Use a reliable strategy
Identify the quantities, choose the operation that matches the situation, calculate carefully, and check whether the result is reasonable.
Check and explain
A correct answer is only part of mathematical understanding. Check units, signs, scale, and whether the result makes sense. Then explain the relationship in words so you can recognize the same structure when the numbers or context change.
