In mathematics, a unit square is a square whose sides have length 1. Often, "the" unit square refers specifically to the square in the Cartesian plane with corners at the four points (0, 0), (1, 0), (0, 1), and (1, 1).
In a Cartesian coordinate system with coordinates (x, y) the unit square is defined as the square consisting of the points where both x and y lie in a closed unit interval from 0 to 1.
That is, the unit square is the Cartesian product I × I, where I denotes the closed unit interval.
The unit square can also be thought of as a subset of the complex plane, the topological space formed by the complex numbers. In this view, the four corners of the unit square are at the four complex numbers 0, 1, i, and 1 + i.
It is not known whether any point in the plane is a rational distance from all four vertices of the unit square. However, no such point is on an edge of the square.
Given a Matrix we can use the unit square to obtain a written explanation of the transformation it represents.

In this video, Joseph Almeida explains how to find the area of a plane (flat) figure by covering it with square units. This is the basic process behind finding the area of a plane figure, which illustrates 3.MD.5.b in the grade 3 Common Core Standards for Mathematics.

Materials spec: Memo-pad sized paper (7cm square) Optional - Glue for actual assembly This is from the book 'Paper Fold-It' by Steve and Megumi video, as seen in my Showcase video. The picture used at the beginning of the video is made of 73 squares. Today you'll see how to make a placemat unit. They don't take that long to make, so you too can make your own placemat in a short time! If you wish to, you can also use a bigger square of paper, even card, to make a coaster. Incidentally, you should follow me on DA and Facebook. :3 http://www.facebook.com/AtelierIlyere http://ilyere.deviantart.com/

In this video, Mr. Almeida explains the concept behind area, which focuses on the unit square. This illustrates 3.MD.5.a in the grade 3 Common Core Standards for Mathematics.
Youtube videos by Julie Harland are organized at http://YourMathGal.com. This video is the third video showing how to convert from square units to other square units. Deals with area. Unit conversions is also referred to as dimensional analysis.

In this lesson students review basic ideas about square roots and then learn how to simplify square roots by using their multiplication property. For the worksheets that goes with this video, click on: http://www.emathinstruction.com/sitebuildercontent/sitebuilderfiles/CCAlgIU9L1SquareRoots.pdf
In this lesson, students explore the graphs of square root functions as well as their domains and ranges. Graphing calculator technology is used to quickly generate graphs and to explore the shifting patterns that we have seen in prior lessons.

In this lesson we see how the method of Completing the Square can be used to help solve for the zeroes of a quadratic function. We compare and contrast this method with the use of factoring to solve for zeroes. You can access the worksheet and homework for this lesson by clicking on: http://www.emathinstruction.com/sitebuildercontent/sitebuilderfiles/CCAlgIU9L5FindingZeroesByCompletingTheSquareV3.pdf
In this video we introduce the algebraic procedure of completing the square in order to find the turning point of a quadratic function. You can download a copy of the worksheet used in this lesson and an accompanying homework by clicking on: http://www.emathinstruction.com/sitebuildercontent/sitebuilderfiles/CCAlgIU8L4CompletingTheSquare.pdf
In this lesson, students first explore how changing the leading coefficient of a quadratic can stretch or compress its overall shape. They then work with completing the square on quadratics in order to identify its turning point.
