In a surprise announcement on Monday, the ailing 82-year-old said he would not stand for a fifth term -- but also cancelled next month's presidential election.
After initial celebration following Bouteflika's announcement, protesters returned to the streets of the capital Tuesday, accusing the 82-year-old of "tricks".
On Wednesday, an AFP correspondent saw middle and high school teachers protesting alongside their students in central Algiers.
"It's important that we teachers mobilise," said Driss, a teacher at a high school in the Algerian capital. "It's about the future of our children."
The protesters carried signs saying: "No to the extension of a fourth term!" Schools in Algeria have been hit by a partial strike in recent days as protests have repeatedly rocked the capital and other major cities.
University students have been at the forefront of the movement, in a country where half the population is under the age of 30 and many have never known any president other than Bouteflika.
The veteran leader's promise of a "national conference" to carry out reforms and set a date for new elections "before the end of 2019" suggested he may stay in office for another year.
