6 Unlawful to potocopy or project witout permission Sirius Education Solutions Dear Students, Te STAAR Grade Matematics assessment measures your knowledge of te Grade mat standards (TEKS). STAAR tests are not designed to measure many important qualities of caracter and intelligence as tis cartoon sows. But performing well on te STAAR tests is important, so you want to do all you can to succeed on tem. Tat s were tis workbook comes in! Qualities Not Measured by STAAR Tests Persistence Curiosity Entusiasm COURAGE Leadersip Creativity Civic-Minded Resourcefulness Sense of Wonder Big-Picture Tinking Compassion Reliability Motivation Humor Empaty Sense of Beauty Humility Resilience Positivity Wat are some oter important qualities of caracter and intelligence missing in STAAR tests? Tis workbook was designed to elp you prepare for te STAAR Grade Matematics test by teacing te skills to approac and answer different STAAR test questions, and by providing practice questions tat are similar to tose you will answer on te actual test. But as good as tis workbook is, it only elps if you use it. So, please use tis workbook! Practicing Smart Is te Secret to STAAR Success Tere is a secret to success on te STAAR tests practice, practice, and more practice. Tis is good news because you are in control of ow muc effort you put into practicing. But not all practice is te same you need to practice smart. First, practice wit test questions tat are very similar to te actual STAAR test. Tat s easy because tis workbook is full of tem! Next, focus on your weaknesses spend extra time on questions you ave trouble wit. Tink of it like tis: if your basketball sot needs improvement, you don t practice dribbling. Instead, you practice sooting. Focusing on your weaknesses also means carefully analyzing eac test question you get wrong. Wy did you get it wrong? Wy is anoter answer correct? You can learn more from test questions you get wrong, so don t be afraid of making mistakes. If your basketball sot is off, you identify wat you are doing wrong (too far left), and correct it wit your next sot (aim furter rigt). Wen you practice, give eac question your full attention. Do not take a break until after you answer te question. Your attention is like a muscle tat you can build by using it, one practice test question at a time. Do you believe unfocused, sloppy practice of your basketball sot will elp you perform during a big game? No! Your attention is your greatest power. You develop it wit practice. Preparing for te STAAR test can actually be a fun callenge. And wen you practice smart, you are building life skills wile you prepare for te STAAR test!

Free Response Grids An interactive review on ow to correctly complete grids and avoid careless mistakes. STAAR Problem-Solving Strategies: Keys to Success Eac year, te STAAR Grade Matematics exam tests te same concepts in similar ways. In fact, it would not be fair unless te STAAR test was consistent from one year to te next. Tis means te STAAR test questions are predictable. So by using tis workbook, you will be well prepared for te actual STAAR test! Te test is callenging, and tere are no secret tricks. But using te following strategies will make a difference. So practice tem as you use tis workbook. Read EVERY Word Carefully and More Tan Once Te STAAR Grade Matematics exam also tests your reading skills because many questions are word problems. Plan to read eac question at least two times. Here are some recommended reading strategies:. First read te problem for te big picture of wat is going on. To do tis, you ignore details suc as names and numbers. Tis first read prepares you for a closer second read. º To sow you understand a problem, write a generalized name for te problem using te format Given, find.. Next, read te problem for supporting facts or details. Circle eac piece of given information and underline wat you are asked to find. º Read graps or tables. Te titles, labels, and scales include important information. º Read all answer coices. You may also want to compare and contrast te answers. Let s apply tese suggestions. Read te question below carefully. Big Picture: Te price was reduced. Te problem name could be: x Te price of a video game was reduced from $ to $. By wat percentage was te price of te video game reduced? STAAR Grade Matematics # F % G % H % J % Given te original price and te new price, find te STAAR Problem-Solving Strategies: Keys to Success tat te price was reduced. Supporting Facts: Original price: $ Sale price after reduction: Read te answer coices. Use estimation to eliminate unreasonable answers. Te price is reduced by $. Tis amount is more less tan one-alf of $. F and G are reasonable answers. Circle te correct coice. H is not reasonable because % is more tan one-alf of $. Wat is te correct answer? Wy?

(.D Lesson ) STAAR strategies are modelled using released test questions. Mixed review of previous lessons in a random order Great Griddables Of te STAAR Grade Matematics test questions, require griddable answers. Tese are just like oter questions, except tat you need to find your own numerical answer (instead of selecting among answer coices). After you ve found your answer, you need to fill it in correctly on your answer document. Here s ow you do it: Use te Boxes Write your answer in te top row of boxes before filling in any bubbles. Te scoring macine only reads te bubbles, but using te boxes will elp you fill in te bubbles correctly. Position wit te Decimal Point Your answer must be positioned properly wit te provided decimal point. Fill in Bubbles Fill in a bubble to matc eac number in te boxes above. Ten ceck your bubbles wit te boxes to avoid making a careless error! Decimals Decimals can be gridded to a maximum of two decimal places (undredts place). So decimals like. need to be rounded to.. For decimals between and, like., you do not need to grid te before te decimal point (altoug you may). You cannot grid fractions, so convert tem to decimals before gridding. Negative Numbers If your answer is negative, fill in te bubble containing a negative sign in te first column. If it s positive, leave te first column blank.
