The tuition is being offered by Yorkshire Ambulance Service (YAS) staff and volunteers as part of Restart a Heart Day.
Youngsters are taught what to do if they come across someone who has suffered a cardiac arrest.
Over the past three years, more than 50,000 pupils at secondary schools across Yorkshire have taken part in the initiative.
Mrs Jones, whose husband died aged 29 after suffering a cardiac arrest during a match in May 2015, is an ambassador for the scheme.
"Restart a Heart Day is an incredible event and I am proud to be a part of something which has the potential to make a difference to so many lives," she said.
"By teaching our children such a vital skill we are changing the future.
"I would encourage as many schools as possible to take part."
Restart a Heart Day takes place on October 16, but the closing date for registration is April 7.
Pupils will also be invited to participate in a poster competition, with the winner receiving a defibrillator for their school.
YAS says that currently less than one in ten people in the UK survives a cardiac arrest.
In Norway, where CPR is taught in schools, the survival rate is 25 per cent.
"If we achieved the same rate an additional 100 lives a week could be saved," said Restart a Heart Day organiser Jason Carlyon, clinical development manager with YAS.
"The event is becoming more successful every year and 2016 was the best yet, when we shared our concept with all UK ambulance trusts to support its roll-out nationally."
