This free math video shows the BEST way I’ve ever seen to introduce the idea of square root. It makes it so clear what the symbol means… one side of the square!!! That’s all there is to it!
It’s best for children to have a good understanding of square numbers before introducing the concept of square root. See my other videos for ideas!
I found this idea at Crewton Ramone’s House of Math. Lots of good stuff there so go check it out!
