Trump, will campaign in New Hampshire, Maine and Iowa on Friday.
"Let's be real. As our first African-American first lady, she's faced pressures I never did, and she's handled them with pure grace", Clinton said to applause.
Trump said his approach would create "a massive education market" and produce better outcomes than the nation's existing public education system. It's also a move to protect his own legacy. The Democratic nominee has called for new spending to add computer science programs and refurbish crumbling buildings.
Over the course of his presidential bid, the NY businessman who says he is worth $10 billion has given about $56 million of his own money.
He cited a 2011 memo from former Bill Clinton aide Doug Band bragging that he had funneled tens of millions of dollars to "Bill Clinton Inc".
But to the frustration of many in his party, Trump has struggled to stay on message. That money "should follow the students", a concept known as portability. He's already been to the battleground states he plans to visit next week, and has also visited Nevada and California on behalf of the Democratic candidate. Trump has called the allegations "absolutely false".
Then Mrs Obama took to the stage, saying of the former first lady: "Yes, she is absolutely ready to be commander-in-chief on day one". "And I am prepared to go much more than that".
In short, that means Clinton doesn't need to win a state now rated as a toss-up to win the White House.

For the season, Osweiler has completed just 58.2 percent of his throws for eight touchdowns and a passer rating of 71.9. The ailing New Orleans defense helps make this play a little more palatable though.
TRUMP: The academic standards adopted in more than 40 states are a frequent target of Trump's ire. "So, obviously, Common Core does not work", he said last month.
In New Hampshire, the state's politics are disproportionately influenced by women: the state's governor, two senators and a majority of its state Senate are women.
Her husband President Barack Obama won North Carolina by just 14,000 votes in 2008. Some of her mastery rubbed off on Mrs Clinton, who by her own admission is not a gifted speaker on stage, but was at her warmest ever sharing the stage with Flotus. "It was to try to come up with a core of learning that we might expect students to achieve across our country, no matter what kind of school district they were in, no matter how poor their family was".
Less than two weeks until the general election, Clinton's appearance alongside the first lady represents a final push to encourage and attract as many swing-state voters as possible. He also needs to win states now leaning Clinton's way. Mrs. Obama's appearances have become a key part of Clinton's effort to fire up women, particularly black women for whom she's a model and a source of pride.
TRUMP: He supports merit pay for outstanding teachers and wants to end teacher tenure that "rewards bad teachers".
Trump leapt on the news this weekend, but so, too, did Clinton, casting Comey's decision to act so close to November 8 as "deeply troubling" as she sought to rally Democratic voters.
Band wrote the 2011 memo to defend his firm, Teneo, describing how he encouraged his clients to contribute to the foundation and provide consulting and speaking gigs for Bill Clinton.
