Until November 6, Newton residents can vote in the Belmont Savings Bank Foundation‘s poll to help direct how the foundation will award grants of $2,000 to $10,000 to local charitable organizations.  Among the candidates is the Newton Schools Foundation to support The Calculus Project, an NPS program to narrow achievement gaps in mathematics by increasing the number of low-income African American and Hispanic American students enrolling in and completing Calculus in high school.  The program began last summer with 95 students, modeled after one that started in Brookline in 2009.  It starts with an intensive four-week summer program and continues support through tutoring in the school year.  A grant of $10,000 would support 10 students.
