Teaching Square Roots (Radicals) For Deep Understanding

square roots and radicals teaching ideas
The square root of nine can be shown visually
with chart paper and blocks.


Whenever possible, the visual form of math concepts should be shown.  It helps students deeply understand concepts.  Often times, blocks and diagrams are used at the lower grade levels.  Using diagrams, hands-on examples, and manipulatives can be useful for older students as well.

This method works only with perfect squares.  
To  teach square roots in a visual way,
 have students place their blocks in equal rows starting from the corner
of the page.  A total of 9 blocks will be added to this diagram.

Students can determine that the square root

Drawing a square within a radical sign is also helpful.
