COMMON CORE

Skills, Practice, and Problem-Solving Applications

8grade

CD-404222

Visit learningspotlibrary.com for FREE activities!

Common Core: Math Workouts 8 is designed to help teachers and parents meet the challenges set forth by the Common Core State Standards. The book is filled with skills practice and problem-solving practice exercises that correspond to each standard. Each page contains two “workouts”—one for skills practice and one for applying those skills to solve a problem. Skills covered include geometry, functions, the number system, expressions and equations, and statistics and probability. With a little time each day, your students will become better problem solvers and will acquire the skills they need to meet the mathematical expectations for their grade level.

Aligned with the Common Core State Standards for Mathematics

Can be used as warm-up exercises or assessments

Includes detailed answer keys

Correlated to Common Core State, National, and Provincial standards. Visit www.carsondellosa.com for correlations.

APP�Y YOUR SKI��S:KristyandPriscillaarebothcorrect.ReflectingpointQ (3,–3) over the x-axis would yield the point (3, 3). Rotat-ingpointQ270��counterclockwiseabouttheoriginwouldalsoyieldthepoint(3,3).Similarly,reflectingpointR (8,–8)over thex-axisor rotating it 270��counterclockwiseabout theoriginwouldyield thepoint (8,8).Therefore,XYcanbedescribedasthereflectionofQRoverthex-axisor the270��counterclockwiserotationofQRabouttheorigin.

thex-coordinate.Thenewpointwouldbe(–x,y). 5. Taking the opposite of the y-coordinate and then

switching the x- and y-coordinates. The new pointwouldbe(–y,x).

6. Takingtheoppositeofboththex-andy-coordinates.Thenewpointwouldbe(–x,–y).

COMMON CORE

Skills, Practice, and Problem-Solving Applications

8grade

CD-404222

Visit learningspotlibrary.com for FREE activities!

Common Core: Math Workouts 8 is designed to help teachers and parents meet the challenges set forth by the Common Core State Standards. The book is filled with skills practice and problem-solving practice exercises that correspond to each standard. Each page contains two “workouts”—one for skills practice and one for applying those skills to solve a problem. Skills covered include geometry, functions, the number system, expressions and equations, and statistics and probability. With a little time each day, your students will become better problem solvers and will acquire the skills they need to meet the mathematical expectations for their grade level.

Aligned with the Common Core State Standards for Mathematics

Can be used as warm-up exercises or assessments

Includes detailed answer keys

Correlated to Common Core State, National, and Provincial standards. Visit www.carsondellosa.com for correlations.
