5 Directions for Completing the Response Grids. Work the problem, and find an answer.. Write your answer in the answer boes at the top of the grid in the Answer Document. Write only one digit or symbol in each answer bo. Be sure to write a decimal point, negative sign or fraction bar in the answer bo if it is a part of the answer.. Fill in a bubble under each bo in which you wrote your answer in the Answer Document. Fill in one and ONLY one bubble for each answer bo. Do NOT fill in a bubble under an unused answer bo. Fill in each bubble by making a solid mark that completely fills the circle. You MUST fill in the bubbles accurately to receive credit for your answer. Answer boes Negative sign Fraction bar Decimal point Number bubbles i

6 ii You can record a mied number in several different ways. You can write it as: a. A whole number and a fraction ( /). Be sure to include a space between the whole number and the fraction. / b. An equivalent fraction (/) / c. An equivalent decimal (.).

7 Directions: Today you will be taking the Ohio Grade Mathematics Practice Assessment. There are several important things to remember:. Read each question carefully. Think about what is being asked. Look carefully at graphs or diagrams because they will help you understand the question. Then, choose or write the answer you think is best in your Answer Document.. Use only a # pencil to answer questions on this test.. For questions with bubbled responses, choose the correct answer and then fill in the circle with the appropriate letter in your Answer Document. Make sure the number of the question in this Student Test Booklet matches the number in your Answer Document. If you change your answer, make sure you erase your old answer completely. Do not cross out or make any marks on the other choices.. For questions with response boes, write your answer neatly, clearly and only in the space provided in your Answer Document. Any responses written in your Student Test Booklet will not be scored. Make sure the number of the question in this Student Test Booklet matches the number in your Answer Document.. If you do not know the answer to a question, skip it and go on to the net question. If you have time, go back to the questions you skipped and try to answer them before turning in your Student Test Booklet and Answer Document.. Check over your work when you are finished.
