Four other backbenchers raised the issue of school funding during the session, including Conservative Michelle Donelan, who asked the prime minister to reaffirm her commitment to fair funding for school.
Last year, after Britain voted to leave the European Union - with Labour incensed at Corbyn's lacklustre campaign in support of the Remain camp - MPs wanted to oust him after only a year in the job. "There can be no turning back", she said.
Corbyn has criticised her apparent u-turn on a snap election, as May previously insisted there would be no vote before 2020. "You can't go into an election with a weak leader, whom the public thinks is incompetent".
The Leader of the Opposition welcomed the move and he and other MPs prepare to hit the campaign trail today (April 20). "Why should anyone believe a word they say over the next seven weeks?"
As a Remainer (albeit not a very convincing one), she has persuaded voters that she is serious about taking the United Kingdom out of the EU.
Labour leader Jeremy Corbyn has rallied activists in key target seat Croydon Central with a speech in which he highlighted a string of recent policy promises to build council houses, help carers and boost the minimum wage.
I welcome the Prime Minister's decision to give the British people the chance to vote for a government that will put the interests of the majority first.

Speaking after a meeting of Labour's National Executive Committee, he said: "There will be no coalition deal with the SNP and a Labour government".
"We understand that, in the immediate run up to an election, signalling a willingness to work with other parties might be hard but we hope you'll agree that the times we are living in require leaders to be courageous and visionary, to actively build a more positive politics". "Independence would lead to turbo-charged austerity in Scotland - not progressive politics".
Opponents also accused Mrs May of ducking out of TV debates during the campaign, after a Downing Street source said she would not be taking part. This is despite broadcasters saying they will have the debate without the Prime Minister. Most forecasters predict Britain's main opposition Labour Party, which has struggled to formulate a position on Brexit, will lose dozens of seats to May's Conservatives.
And attacking top bosses, he will say: "If I were Southern Rail or Philip Green, I'd be anxious about a Labour Government".
If he defied the polls, which give the Tories a double-digit lead, to get into No 10, Mr Corbyn said he would take on the "cosy cartels. rigging the system in favour of a few powerful and wealthy individuals and corporations".
"We will not let the elite extract wealth from the pockets of ordinary working people any longer".
