These tasks are grade-level formative performance assessment tasks aligned to the Common Core State Standards for Mathematics. Some have accompanying scoring rubrics and discussion of student work samples. Others, such as the Dana Center Early Mathematics Tasks, connect to children’s literature.

You may download and use these tasks for professional development purposes without modifying the tasks.

The tasks below are arranged by grade level. To search for tasks by mathematical strand or to see information about alignment to specific standards, use the "shortcuts" field at the top of the page, or visit the Common Core mathematical content standards page.

2.MD.2

Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.

Performance Assessment Tasks

2.MD.4

Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

2.MD.6

Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ..., and represent whole-number sums and differences within 100 on a number line diagram.
