All primary schools across the Forth Valley are closed, as staff walk out in a dispute over pay.
Members of three trade unions have rejected a pay offer from the Scottish Government.
All local secondary schools are shut tomorrow, due to the pay dispute.
The offer includes rises of up to 6.85% for the lowest-paid staff - but unions were asking for a 10% rise.
Last-ditch talks yesterday to try and resolve the dispute failed to reach an agreement.
Dr Patrick Roach, NASUWT General Secretary, said:
“The failure of the Scottish Government and COSLA to offer any improvements in recent days means we are left with no choice.
“It just cannot be acceptable to expect teacher pay to be cut yet again at a time when we are facing the worst cost of living crisis in a generation.
“NASUWT members will not stand by and continue to watch their pay and living standards shrink further.
“The Government and the employers can end this dispute and they can do that by making a substantial offer that will pay teachers what they deserve.”
