• Welcome to R. Castillo's Math Class!

    Hello. My name is Mr. Castillo and I teach 7th grade math, and 8th grade Algebra I this year at E. T. Wrenn Middle School.
    In Algebra I, we will build a foundation for all higher math classes. This 
    course will review algebraic expressions, integers, and mathematical properties that will lead into working with variables and linear equations. There will be an in-depth study of graphing, polynomials, quadratic equations, data analysis and systems of equations through direct class instruction, group work, homework,student projects and technology.

    In 7th grade, we will  This year we will build upon the work done with fractions and decimals to include operations with positive and negative rational numbers. Students will extend their understanding of ratios to study proportionality, similarity, percent, slope and probability. Other topics that will be covered are surface area and volume for three-dimensional figures, displaying and interpreting data, graphing ordered pairs on the coordinate plane, and solving two-step linear equations.
