Common Misconception 1
A common misconception is that students may confuse the values of different coins and bills, thinking, for example, that a nickel is worth more than a dime because it is larger.
Intervention 1
To remediate this, use hands-on activities with real or play money to practice identifying and counting different coins and bills. Reinforce learning with visual aids and repetition.
Common Misconception 2
Another misconception is that students may incorrectly use the $ and ¢ symbols interchangeably, not understanding that $ represents dollars and ¢ represents cents.
Intervention 2
Provide visual aids and practice problems that emphasize the correct usage of $ for dollars and ¢ for cents. Reinforce the difference through consistent practice and examples.
