Teacher's field guide

What Students Need to Do: Students compare how much the same deposit earns at two interest rates. They explain why a higher rate makes savings grow faster when the starting amount and time are the same.
What Mastery Looks Like: A student calculates one year of interest on $100 at 2% and 5%, getting $2 and $5. They explain that the 5% account ends with more money because it pays more interest.
Common Misconceptions: Students may think 5% interest means $5 for every deposit, no matter its size. Some confuse interest earned with a fee paid to the bank, or compare accounts with different starting amounts.
How to Assess It: Exit ticket: You put $200 in each of two accounts for one year. One pays 2% interest and the other pays 4%. How much interest does each earn, and which grows faster?

Lesson moves

Give pairs 100 paper squares as a $100 deposit, then have them add 2 squares and 5 squares to model two annual rates.
Ask students to write two sentences explaining why $200 earns more interest at 4% than at 2% after one year.
Play a rate-match game with cards showing deposits of $100 or $200 and rates of 2% or 5%; students match each to its yearly interest.
Show two savings account ads with different rates and ask students which pays more on a $500 deposit after one year.
