Reviewing and Practicing for the Multi-Step Problems:ĭiscuss a plan for solving these types and model how you would analyze the task… Why was it difficult? What caused a problem or might have been confusing for you?.After arriving at the answer, guide students’ reflection and have them share out:Īsk students to rate the difficulty of the question with a show of hands: hold up one finger for easy, two for medium, three for hard.Give the correct answer and have groups who got it correct model their thinking of how they got the answer. Encourage open dialogue among group members as they select answers. Give questions to pairs or small groups to answer.Then have students model their own thinking on the next question. Answer the question yourself and think out loud, describing how you would go about eliminating wrong answers. Have students discuss the possible answer as a class.Project a sample question for the class and… Instead of choosing a correct answer from a list of options, ask students to solve problems and enter their answers in grids provided on an answer sheet on your classroom and common assessments.Encourage students to express quantitative relationships in meaningful words and sentences to support their arguments and conjectures.Assign students math problems or create classroom-based assessments that do not allow the use of a calculator.Ask them to discuss how to arrive at solutions. Organize students into small working groups.Ensure that students practice solving multi-step problems.Therefore, the model that can be used to relate the pressure and the depth is p = 0.44 d + 14.74. Then one needs to determine the pressure due to the atmosphere or, in other words, the pressure when the diver is at a depth of 0. Calculating this gives equals comma or 0.44. To determine the linear model, one can first determine the rate at which the pressure due to the atmosphere and surrounding water is increasing as the depth of the diver increases. If the pressure increases at a constant rate as the scientist’s depth below the surface increases, which of the following linear models best describes the pressure p in pounds per square inch at a depth of d feet below the surface?Ĭhoice B is correct. At a depth of 14 feet, the pressure is 20.9 pounds per square inch. As the scientist descends, the pressure increases linearly. When a scientist dives in salt water to a depth of 9 feet below the surface, the pressure due to the atmosphere and surrounding water is 18.7 pounds per square inch. 2016: Math - Calculator questions with answers and explanations and Math - No Calculator questions with answers and explanations 2017: Math - Calculator questions with answers and explanations and Math - No Calculator questions with answers and explanations 2018: Math - Calculator questions with answers and explanations and Math - No Calculator questions with answers and explanations 2019 Math - Calculator questions with answers and explanations and Math - No Calculator questions with answers and explanations 2019: Math - Calculator questions with answers and explanations and Math - No Calculator questions with answers and explanations 2020: Math - Calculator questions with answers and explanations and Math - No Calculator questions with answers and explanations For more information about the MCAT exam, visit PSAT 11 - Oct.
