A square is a special type of quadrilateral, which is a polygon with four sides. What sets a square apart from other quadrilaterals is that all four of its sides are equal in length, and all four of its angles are right angles (90 degrees).

1. **Equal sides:** All four sides of a square are of equal length. This means if one side is 's', then all sides are 's'.

2. **Right angles:** All four angles of a square are right angles (90 degrees).

3. **Diagonals:** The diagonals of a square are equal in length and bisect each other at right angles.

4. **Perimeter:** The perimeter of a square is four times the length of one of its sides, so if the length of a side is 's', then the perimeter is 4s.

5. **Area:** The area of a square is the length of one of its sides squared, so if the length of a side is 's', then the area is s^{2}.

Perimeter = 4 × side length (P = 4s)

Area = side length × side length (A = s^{2})

To understand squares better, make sure to focus on the following:

- Understand the definition of a square and its properties.
- Learn how to calculate the perimeter and area of a square using the formulas provided.
- Practice identifying squares and their properties in everyday objects and shapes.
- Work on solving problems involving squares to solidify your understanding.

Remember to ask your teacher or tutor for help if you have any difficulties with understanding squares and their properties.

Connections to the Grade 4 Focal Points (NCTM)

Algebra: Students continue identifying, describing, and extending numeric patterns involving all operations and nonnumeric growing or repeating patterns. Through these experiences, they develop an understanding of the use of a rule to describe a sequence of numbers or objects.
