Clarifications

These tasks should support Grade 3 fraction and area work. Technology-enhanced tasks could involve partitioning a shape into parts with equal areas; more traditional tasks could involve expressing the area of each part as...

Depth of Knowledge

  • M-DOK1

    Recall includes the recall of information such as fact, definition, term, or a simple procedure, as well as performing a simple algorithm or applying a formula. That is, in mathematics a one-step, well-defined, and straight algorithmic procedure should be...

Task Description

Prompt Features: The student is prompted to select a shape that displays the given attributes. Stimulus Guidelines: Item difficulty can be adjusted via these example methods: Recognizes rhombuses, rectangles, and squares. Recognizes shapes that are quadrilaterals and shapes...

Stimulus

The student is presented with a description of a shape which may include:

  • the name of the shape (e.g., quadrilateral, parallelogram)
  • the attributes of the shape (e.g., 4 sides)

Example 1

Example Stem: Decide if each shape is a quadrilateral. Select Yes or No for each shape.

Yes No
A shape is shown with 5 sides.
A shape is shown with 4 sides.
A shape is shown with 4 sides.

Rubric: (1 point) The student correctly identifies each shape as Yes or No (e.g., N, Y, Y).
