    Professional Bio:

    My name is Margo Petre and I have been teaching 5th Grade Mathematics here at Cambria Heights Elementary School since 2014.

    I graduated from Cambria Heights in 2004 and pursued my Elementary/Special Education degree at St. Francis University, where I graduated with honors in 2008.

    I earned my Master's degree in Curriculum & Instruction from Gannon University in August 2019.

    I have been teaching for 12 years, including service with the IU8 and Central Cambria Middle School.

    I really look forward to teaching in my home district with a great bunch of 5th graders!

    How to help your child learn AND love MATH!

    1. Encourage children to play math puzzles and games. Puzzles and games – anything with dice, really – will help kids enjoy math, and develop number sense, which is critically important.

    2. Always be encouraging and never tell kids they are wrong when they are working on math problems. Instead find the logic in their thinking.

    3. Never associate math with speed. It is not important to work quickly, and we now know that forcing kids to work quickly on math is the best way to start math anxiety for children, especially girls.

    4. Never share with your children the idea that you were bad at math at school or you dislike it – especially if you are a mother. Researchers found that as soon as mothers shared that idea with their daughters, their daughters’ achievement went down.

    5. Encourage number sense, having an idea of the size of numbers and being able to separate and combine numbers flexibly.

    6. Perhaps most important of all – encourage a “growth mindset” – let students know that they have unlimited math potential and that being good at math is all about working hard… use growth praise such as “It is great that you have learned that;” “I really like your thinking about that;” “You have worked really hard to learn that.”
