A Staten Island teacher with a prior manslaughter conviction was booted by the Department of Education for allegedly menacing an ex-boyfriend.

Elementary-school teacher Kim DePrima — whose manslaughter rap came after her two pit bulls mauled an elderly neighbor to death in 2008 — was canned for allegedly getting a friend to shoot up the home of her old flame earlier this year.

Although prosecutors dropped attempted-murder charges against DePrima last summer, the city arbitrator concluded that she had encouraged the intimidating act.

“‘I told you you are dead, motherf–ker!’” her ex-beau told cops she said to him the night bullets flew.
