Welcome to Mrs. Mastorio's 3rd Grade Math Web Page 

September 2, 2026

Dear Parent(s)/Guardian(s),

 

My name is Mrs. Mastorio and I will be your child’s third grade Math teacher this year. As you know, I will spend a great deal of time with your child. Because of this, I would like to take this opportunity to tell you a few things about myself and what I expect from both you and your child.

This is my twenty-second year teaching in Irvington Public Schools and my first year here at University Elementary school.  I have previously taught fifth, second, fourth and kindergarten all at Grove Street Elementary School. I graduated from Rutgers University in 2003 with a Bachelor’s degree and obtained my teaching certificate in 2006 from New Jersey City University. In September 2015, I became a mother to my son, Jase. He will be in Sixth grade this year. In December 2018, I had my second son Logan and he will be in Second grade this year. In August 2025 I married my husband Joe. 

The first three days of school I am going to spend time going over our rules and my expectations and procedures. All important notes home will be sent via ClassDojo as well as in their folders. Please check your child’s folder and ClassDojo daily to ensure your child is keeping up with the assignments and that you get important information. It is very important that the emergency contact information is kept up to date throughout the school year. Please let me or the main office know immediately if there are any updates.

Third grade is an important grade because this is where many children move from counting and basic facts into deeper number sense, place value, multiplication, division, and problem solving. Small gaps in understanding can show up in homework, quizzes, and class discussions, but they are common and very workable with clear feedback and guided practice. Parents often see the biggest growth when support is specific, patient, and matched to how their child learns, not just focused on getting answers faster. Strong foundations in third grade math support later work in fractions, multi-digit operations, measurement, and algebraic thinking.

As a parent/guardian, YOU are the most important person in your child’s life and we need to work together for your child’s benefit.  We need your support with the attendance, assignments, academic goals, and the citizenship plan I have set for the students.  I will be using Class Dojo to keep in contact with you. I also encourage you to use the “PowerSchool Parent Portal” on the Irvington website to continuously check your child’s grades. For more information on this please see Ms. Amoatey, our school counselor. You can reach Ms. Amoatey at 973-399-6826 Ext 1112  or via email [email protected]. With school and home working together, I know your child can have a successful year.

Ifyou have any questions, please do not hesitate to email me at [email protected] or send a message on ClassDojo. Thank you in advance for your cooperation. I look forward to educating your child this year.

 

Sincerely,

 

Mrs. Mastorio
