In this task using a number line, students must partition the interval between 0 and 1 into eighths.

This task assesses a student's ability to use the addition rule to compute a probability and to interpret a probability in context.

Students are exptected to identify the slope of the line with the unit rate in this real world problem.

Collaborative research project in which undergraduate geoscience curricula at Research 1 institutions are compared. This project uses the methods of science to explore a topic that beginning students can understand. This project uses rubrics for self, peer, and instructor assessment.

This professional development article identifies resources that show young learners (K-grade 5) how scientists study Earth's climate and make predictions. The online lessons either allow students to collect and analyze data or learn about tools and technologies that make data collection possible. The lessons are aligned with national content standards for science education. The article appears in the free, online magazine Beyond Weather and the Water Cycle, which examines the recognized essential principles of climate literacy and the climate sciences for elementary teachers and their students.

n this task, students are able to conjecture about the differences in the two groups from a strictly visual perspective and then support their comparisons with appropriate measures of center and variability. This will reinforce that much can be gleaned simply from visual comparison of appropraite graphs, particularly those of similar scale. Students are also encouraged to consider how certain measurements and observation values from one group compare in the context of the other group.

College Success takes a fresh look at what it means, in today’s world, with today’s students, to be successful in college.Although many of the topics included—from study skills to personal health, from test-taking to managing time and money—will look familiar to those who have used student success texts that have been around for many editions, College Success takes a new approach. The focus is on realistic, practical tools for the students who need them. This is a book designed, frankly, for students who may have difficulty with traditional college texts. The style is direct and to the point. Information is presented concisely and as simply as possible. This is not a weighty tome that discusses student success—this is a manual for doing it.College student demographics have changed considerably in recent decades. More than a third of all students enroll not directly from high school but after a delay of some years. More students are working and have families. More students come from varied ethnic and cultural backgrounds. More students are the first in their family to attend college. More students have grown up with electronic media and now read and think in ways different from the previous generation. With these and so many other cultural changes, more students are not well prepared for a college education with the study skills and life skills they need to become successful students.For each student to get the most out of College Success and their college experience they must understand who they are as it relates to college. To that end, in every chapter students explore themselves, because success starts with recognizing your own strengths and weaknesses. Students make their own goals based on this self-assessment, determining what success in college really means for them as individuals. Interactive activities then help students learn the choices available to them and the possibilities for improving their skills. Skills are presented in step-by-step processes, tips for success in manageable highlighted displays. Most important, students always see the value of what they are reading—and how they can begin to apply it immediately in their own lives.College Success is intended for use in Freshmen Orientation, Study Skills or Student Success courses. A 2009 study revealed that currently nationwide, 34% of college freshmen do not return to their college for their sophomore year. This book is designed to help change that.

The purpose of this task is to help students understand the connection between counting and cardinality. Thus, oral counting and recording the number in digit form are the most important aspects of this activity. However, teachers can extend this by making a bar graph about how many students are wearing the color each day.

This is a laboratory exercise designed to allow students to further investigate the light spectrum. This lab is used to have students view the light spectrum first hand as opposed to using lecture alone.

The primary purpose of this problem is to rewrite simple rational expressions in different forms to exhibit different aspects of the expression, in the context of a relevant real-world context (the fuel efficiency of of a car). Indeed, the given form of the combined fuel economy computation is useful for direct calculation, but if asked for an approximation, is not particularly helpful.

Three in-class lecture demonstration questions to test and build understanding of DC circuits are presented. These questions cover simple series and parallel circuits, and a more complicated circuit that is fundamental for understanding this topic.

Students observe a burning candle and the byproducts given off through the burning process. This observation leads to a discussion to the effects of air pollution on our lives.

This activity consists of classroom lessons where children observe tree leaves and compare and contrast those leaves leading to an understanding of the terms deciduous and evergreen (and also coniferous). They then use that learning to help them identify the kind of tree based on samples on a chart.

This task gives students an opportunity to work with exponential functions in a real world context involving continuously compounded interest. They will study how the base of the exponential function impacts its growth rate and use logarithms to solve exponential equations.

The purpose of this task is for students to compare fractions using common numerators and common denominators and to recognize equivalent fractions.

This task is meant to address a common error that students make, namely, that they represent fractions with different wholes when they need to compare them. This task is meant to generate classroom discussion related to comparing fractions. Particularly important is that students understand that when you compare fractions, you implicitly always have the same whole.

This task is appropriate for assessing student's understanding of differences of signed numbers. Because the task asks how many degrees the temperature drops, it is correct to say that "the temperature drops 61.5 degrees." However, some might think that the answer should be that the temperature is "changing -61.5" degrees. Having students write the answer in sentence form will allow teachers to interpret their response in a way that a purely numerical response would not.

The purpose of this task is to foster a classroom discussion that will highlight the difference between multiplicative and additive reasoning.

The purpose of this task is to assess studentsŐ understanding of multiplicative and additive reasoning.

This lab activity is designed to allow students to experience what an increase in mechanical advantage means. Students determine the mechanical advantage of three pulley set-ups. Students also measure the work input and output, then calculate the efficiency. Finally, students determine the relationship between the mechanical advantage and the efficiency of the pulleys.
