Academic Context and Connections
Finer grained standards that are part of this one
In Grade 2, students reason with shapes and their attributes.
Construct viable arguments and critique the reasoning of others.
In Grade 4, students draw and identify lines and angles and also classify shapes by properties of their lines and angles.
Can you draw a quadrilateral that is not a rhombus, rectangle, or square?
This expectation supports the major work of the grade.
Look for and make use of structure.
In Grade 3, this expectation connects to developing an understanding of fractions as numbers.
(Given two identical squares) Divide each of these squares into four equal parts, but in different ways. If you compare a part of one with a part of the other, are their areas the same? How do you know?
Reason abstractly and quantitatively.
