Jigsaw Sudoku or Irregular Sudoku (Mini Sudoku Series #23)

Irregular Sudoku is also known as Jigsaw Sudoku. As both of these names are famous, I am using both these names while publishing this puzzle type.
Recently, my 9-year-old daughter started learning Sudoku variations and I have one more 6-year-old student who is very much interested in learning Sudoku. For both of them, I am creating Mini Sudoku Variations of Sudoku so that they can easily understand these puzzles. I have earlier created 6x6 Irregular Sudoku which was published here with the title Irregular Sudoku (Mini Sudoku Series #19). However, I felt that to make kids understand this puzzle type 5x5 Sudoku will be better. So, I created this puzzle but giving the minimum hints possible here, so most of the techniques to solve Jigsaw or Irregular Sudoku can be applied here.
I am posting this 5x5 Jigsaw or Irregular Sudoku as 23rd Sudoku in Mini Sudoku Series. Can you solve these Sudoku Puzzles?

Rules of Irregular Sudoku

Place a digit from 1 to 5 in each empty cell so that each digit appears exactly once in each row, column, and outlined region. Each outlined region is marked by thick borders.
