Predecessor and successor are important concepts in mathematics that are often used in various fields such as computer science, engineering, and business. Understanding these terms is essential for building a strong foundation in mathematics.

These terms are used for a series of whole numbers. The number that appears just before the given number in a series is called Predecessor.

The number that appears just after the given number in a series is called Successor.

Predecessor is a number that comes before another number, and it is one less than that number. Predecessor of any given number is obtained by subtracting 1 from the given number.

**For example **: Predecessor of 68 is 68 – 1 = 67, similarly predecessors of the numbers 10, 15, and 20 are 9, 14, and 19, respectively.

After kids understand the concept of predecessor, introduce the concept of successor. A successor is a number that comes after another number, and it is one more than that number. Successor of any given number is obtained by adding 1 to the given number.

**For example :** Successor of 68 is 68 + 1 = 69. Similarly, successors of the numbers 10, 15, and 20 are 11, 16, and 21, respectively.

Kids can easily relate to real life examples. For instance, if a student is born in the year 2020, then their successor would be the year 2021, which comes after 2020 and predecessor of the year 2020 would be the year 2019.

**Jigsaw Puzzle : **

- There are puzzle pieces of 2 digit numbers along with P and S pieces.
- The level of the game is decided as per the age of the child; initially, 2 digit numbers can be taken.
- Kids can be instructed to make sets of predecessors and successors arranging numbers with the correct P or S piece.
