01

What Students Need to Do

Students interpret a definite integral as net accumulation and signed area. They estimate with sums, find antiderivatives, and use bounds to calculate exact values.

02

What Mastery Looks Like

A student can estimate accumulation with rectangles and calculate exact values using antiderivatives. The student handles bounds, signs, units, and constants correctly and explains the result in context.

03

Common Misconceptions

Students may treat all area as positive, even when the graph is below the axis. They may forget the constant of integration for indefinite integrals or apply bounds before finding an antiderivative. Some confuse an integral’s value with the height of the function.

How to Assess It

Exit ticket: For f(x) = 2x - 3, compute ∫₀³ f(x) dx. Sketch the graph and explain why the result differs from the total geometric area.

1. 01

   Use cut paper rectangles under a graph to build left and right Riemann sums, then compare both estimates with the exact value.

2. 02

   Ask students to explain what a negative definite integral means for water flowing into and out of a tank.

3. 03

   Run a card sort matching graphs, definite integrals, signed areas, antiderivatives, and numerical values.

4. 04

   Give students velocity data from a short trip and have them estimate displacement from a velocity-time graph.
