Course 2/3 Math in Focus

Math in Focus
  • Math in Focus addresses topics in greater depth at each grade.  
    Please reference the 6-8 scope and sequence to see how mathematics skills are introduced and expanded within each grade level.
  • This year, students in Course 2/3 will focus on:
    • developing a unified understanding of numbers, recognizing fractions, decimals and percents as representations of rational numbers
    • converting between a fraction and decimal form of an irrational number
    • extending addition, subtraction, multiplication and division to all rational numbers
    • maintaining the properties of operations and the relationships between addition and subtraction, and multiplication and division
    • viewing negative numbers in terms of everyday context
    • explaining and interpreting the rules for adding, subtracting multiplying and dividing
    • extending their mastery of the properties of operations to develop an understanding of integer exponents, and to work with numbers written in scientific notation
    • using arithmetic of rational numbers as they formulate expressions and equations with one variable, and use these equations to solve problems
    • strategically using and implementing procedures to solve linear equations with one variable
    • developing an understanding that when you use the properties of equality and the concept of logical equivalence, they maintain the solutions of the original equation
    • recognizing equations for direct and inverse proportions
    • using linear equations and systems of linear equations to represent, analyze and solve a variety of problems
    • strategically choosing and efficiently implementing procedures to solve linear equations.
    • analyzing relationships among two-dimensional figures using scale drawings and informal geometric constructions
    • using ideas about distance and angles, how they behave under translations, rotations, reflections and dilations
    • analyzing ideas about congruence and similarity to describe and analyze two-dimensional figures
    • solving problems involving the area and circumference of a circle and surface area of three-dimensional objects.
    • expanding proficiency with single data distributions and random sampling to generate data sets.
