Course 2/3 Math in Focus

Math in Focus addresses topics in greater depth at each grade.Please reference the 68 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 twodimensional 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 twodimensional figures
 solving problems involving the area and circumference of a circle and surface area of threedimensional objects.
 expanding proficiency with single data distributions and random sampling to generate data sets.
 developing a unified
understanding of numbers, recognizing fractions, decimals and percents
as representations of rational numbers
