Gemma Devonish, 42, was found with stab wounds in Nutfield Close, Carshalton, on December 19.
Officers and the London Ambulance Service attended the scene where Ms Devonish was pronounced dead, the Metropolitan Police said.
Her long term boyfriend, James Madden, 38, of Railton Road in Brixton, is charged with her murder.
On Tuesday (March 11) he appeared at Croydon Crown Court from HMP Belmarsh.
During a brief hearing Judge Peter Gower KC set a trial date in October, with the trial expected to last around two weeks.
Madden will be asked to enter a plea to the murder charge at the same court in April.
The head of Roseberry School, an all-girls school in Epsom where Ms Devonish taught, described her as “the kindest and most gentle of people” who was “devoted to her work and loved her pupils”.
David Lach told the BBC: “She was a wonderful teacher who inspired a love of her subject among all her students and went above and beyond to offer her time, expertise and care to the students in her classes and in her year group.
“Her loss to our school is incalculable, but she leaves the most incredible legacy in the hundreds of students that have been touched by her energy, passion and empathy.
“The hearts of the Rosebery community will be broken by this awful news, but the strength of our school has always been the way we have supported each other in times of adversity.”
A post on Rosebery School’s website said: “The entire Rosebery community is devastated by the sudden and unexpected death of Miss Gemma Devonish.
“Our thoughts are with Gemma’s mother and sister, extended family and friends, at this deeply distressing time.”
After her death bundles of flowers were placed next to a memorial bench on Trinity Square, with a sign reading #SayHerName.
The bench was created by local artists Samia Tossio and her sister Hana Horack-Alyafi, to raise awareness to women and girls who have been killed by male violence.
It was unveiled by Sutton Council on March 2022, coinciding with International Women’s Day.
Many tragic tributes have since been shared by those who knew her.
Rosie Friend said: “RIP Miss Devonish, you were so loved by so many people and looked out and supported so many of us going out of your way to make sure that everyone was supported and put smiles on everyone’s faces.”
Niki Hodson-Aubrey said: “How lucky were we to know this incredible woman and how lucky were her students to experience her radiance and phenomenal teaching.
“A true beauty, taken selfishly in her prime by someone who just couldn’t handle her light. Shine bright Gemma.
“You will always be remembered for your sparkle. We keep your light burning through our candles as you remain always in our heart.”
