The Foxes had promotion wrapped up with weeks to spare and claimed a 2-0 victory away to Huddersfield on Saturday.
But boss Pearson said: "The 100-point total has given the players something to focus on."
Leicester reached 99 points and with a home game against Doncaster to come, Pearson said: "All we can do is keep playing well and hopefully reach the 100 or 102-point mark."
Pearson made six changes against Huddersfield but his side never looked in danger of slipping up.
He said: "We have illustrated we have a really strong squad and are capable of still performing at this stage of the season."
Pearson praised his players and added: "This is one of the hardest leagues in the world to be successful in.
"It is always difficult for teams coming down from the Premier League to be a hit straight away.
"There are a number of big clubs who have struggled to get out of this division. We have been in the Championship for 10 years and that has been frustrating for the fans and everyone at the club."
Pearson said he had carefully selected players with good footballing ability and the right mental attitude, adding: "We have some really good choices in the squad and it is difficult to keep them all happy.
"They have shown a level of support for each other and that is as important as their technical ability. We have a squad with good technical ability and character."
Pearson knows Leicester will have to improve to make an impact in the Premier League, but said: "We are on 99 points so we are not too shabby.
"We know we have to improve in certain areas but my glass is always half full. Contrary to certain people's belief that I am a miserable so-and-so I am not."
Matty James smashed a shot against the underside of the crossbar before Gary Taylor-Fletcher opened the scoring against one of his former clubs.
James' breakaway allowed Lloyd Dyer to set up Taylor-Fletcher who struck a curler in off the far post.
In the second half Dyer forced two saves from Town keeper Alex Smithies before skipper Wes Morgan fired home from James' corner late on.
Pearson added: "It was nice to see that one go in. We feel we should have scored more goals from setplays."
Huddersfield boss Mark Robins said he would have liked to have seen more from his players.
He said: "We were all right box to box but in the final third we didn't do enough.
"Having said that we were playing the champions who look like a Premier League outfit now. They have done unbelievably well."
Town chairman Dean Hoyle said in his programme notes that he thought the team had "under achieved" this season.
Robins said: "I have to share that view. Dean is talking as a supporter and wants the best for the club.
"He also says we have to work smarter because we don't have unlimited resources.
"That means we have to bring players through and that means inconsistencies and challenges.
"The disappointing thing is that 10 or 15 games ago (we) were closer to the top than the bottom.
"We want to be better but the remit for this season was to embed a style of play and bring youngsters through.
"Next season we have got to be challenging higher up the league."
