1 north carolina End of Grade Mathematics North Carolina Practice and Master 8

2 FOR THE STUDENT North Carolina End-of-Grade Mathematics Practice and Master is a mathematics review program. It can help ou prepare for such end-of-grade tests as the North Carolina End-of-Grade Mathematics Test. This book has practices. In each practice, ou will answer 80 multiple-choice questions. You ma use a calculator and graph paper to answer an of the questions. You must use a calculator for an calculation involving pi. Use the answer form on page and the back cover of this book to record our answers. Be sure to fill in the answer bubbles completel. If ou change an answer, erase our first answer full. As ou do the practices in North Carolina End-of-Grade Mathematics Practice and Master, use the testing tips below. The can help ou be a better test taker. Testing Tips for Answering Multiple-Choice Questions Read each question carefull before ou tr to answer it. Be sure ou know what the question is asking ou to do. Cross out an answer choices that are not reasonable. Then make our choice from the remaining choices. Read the question again. Check that our answer makes sense.
