What This Standard Means
What Students Need to Do
- Students find the money left after subtracting total costs from total sales income. They use information from a situation to choose the correct amounts and calculate accurately.
What Mastery Looks Like
- Students identify the total cost and total sales income in a word problem. They subtract cost from sales income and explain what the result means.
Common Misconceptions
- Students may subtract in the wrong order or treat all sales income as profit. They may also ignore costs or use the cost of one item instead of the total cost.
How to Assess It
- Give this exit ticket: “A student spends $36 making bracelets and sells them for $56 total. Find the profit and show an equation.”
