Gakuen Alice is a really good manga! Some manga I have read that are like Gakuen Alice:

Shugo Chara

Everybody at Seiyo Elementary thinks that stylish and super cool Amu has it all: But nobody knows the real Amu, a shy girl who wishes she had the courage to truly be herself. Changing Amu's life is going to take more than wishes and dreams - it's going to take a little magic!

One morning, Amu finds a surprise in her bed: three strange little eggs. Each egg contains a Guardian Character, an angel-like being who can give her the power to be someone new. With the help of her Guardian Characters, Amu is about to discover that her true self is even more amazing than she ever dreamed.

Cardcaptor Sakura

Sakura Kinomoto was just an average 4th Grader - loved P.E., hated math - until one day, while looking through her father's library, Sakura found the Clow, an enchanted book designed to hold a set of magical Clow Cards. But when Sakura opened the book, it was empty. Talk about disasters!! Cerberus, the Creature of the Seal, emerged from the cover of the book and told Sakura the cards must be returned to the book. "If the cards aren't in the book, they come to life and do evil!" Kero formed a contract with Sakura making her a Cardcaptor and together with Sakura's best friend, Tomoyo, they embark on a mystical journey to capture all the Clow Cards before the Cards can wreak chaos and destruction.

They can do things that other babies can't! But before Tamae can keep them--she has to prove herself to her mother. Out of all her siblings, she gets the worst test scores, and the last thing she needs is another distraction.

Ciel

Because a count tries to kidnap her, Yvienne flees to the Lowood Institution for wizardry and witchcraft, forced to leave her family.

In the school, she meets interesting people, like January Lightsphere who comes from a noble but peculiar family, or Lariatte, an heir to an orthodox fighter family, who might yet become her closest friend.
