The second part of this section focuses on rational numbers, Pythagorean Theorem, scientific notation, posititve and negative exponents, and square roots. They will also solve for a variable in formulas and equations involving rational numbers. Transformations of figures in the plane are explored. These transformations include translations, reflections, and rotations. Students review naming, rounding, and subtracting of whole numbers and decimals in preparation for multiplying and dividing whole numbers and decimals.
Students continue to build number sense through measurement and rounding.
The concepts of first quadrant graphing, function tables, and missing addend equations are introduced as well. They work with decimals include multiplying by powers of ten. A strong emphasis on exponents and estimation runs throughout the chapter. The chapter provides problem-solving settings that make connections with the multplication mprocess and with equations. After dividing a decimal by a whole number, students encounter problems with zeros in the quotient.
