This article describes the two types of reasoning in fraction conceptions that students often use, "gap" and "missing piece," and one that the authors aspire their students to reach, "residual." Each of these types of reasoning are underpinned by a different conception of fractions. Students who use "gap…

The Common Core has emphasized reading for comprehension, including making inferences. However, little is known about the instructional materials included in core literacy programs for teaching inferences. The purpose of this study was to determine the frequency of background, anaphoric, predictive, and retrospective inferences in instructional…

The Common Core State Standards for Mathematics (CCSS-M) aim to engage students in complex mathematical practices, including modeling, reasoning, and argumentation. Currently, little is known about how teachers' daily instruction supports these practices. This study draws upon data from daily logs completed by third-, fourth-, and fifth-grade…

The population of emerging bilinguals (EBs) is rapidly growing across the United States leaving many teachers wondering how best to teach these students to read and write effectively in English. Concurrently, and as a result of the Common Core State Standards, elementary school students are required to produce more sophisticated writing than ever…

A fundamental claim for Common Core State Standards (CCSS)-aligned assessments is that they will lead to better teaching practices. The purpose of this study is to seek evidence in support of this claim by surveying teachers about their instructional practices, test preparation strategies, and test score use both before and after the introduction…

The 10th anniversary of Common Core's launch offers the opportunity to take stock of the impact these nearly national standards have had on student learning, as well as their future prospects. In this article, Morgan Polikoff shares his view that the standards movement in general, and Common Core in particular, have achieved all they are going to…

In this featured lesson, entitled "Fishy Feeding Frenzy," fourth-grade students engage in a classic science activity that requires them to experience the interdependent relationships of organisms in an ecosystem. The students explore how adaptations increase the survival of a member of a species by participating in an active "fishy…

To an outside observer, there is nothing really novel about whiteboarding. An observer passing a classroom would see students using dry-erase markers to write and sketch their ideas on large, dry-erase-type boards. However, like so many things in education, the subtleties that an outside observer might not notice are the precise things that make…

The Common Core State Standards, released in 2010, were rapidly adopted by more than 40 states. Champions maintained that these rigorous standards would transform American education, but the initiative went on to encounter a bumpy path. A decade on, what are we to make of this ambitious effort? What kind of impact, if any, has it had on the…

Twenty-one fourth graders are actively listening and constructively critiquing mathematical statements. Each student is eagerly participating in mathematical discussions that involve multiple strategies to discover solutions. What a dramatic change since the first months of school when the same students sat as quiet as stone statues, hoping their…

Children using robotics for engineering, science, technology, and mathematics (CREST-M) is an ongoing curriculum creation and evaluation project developing math-focused science, technology, engineering, and mathematics (STEM) curriculum units that incorporate storytelling with math and are designed to be engaging for students from backgrounds…

In this article, the authors show how groups of 2nd- and 4th-grade students in an urban school district responded to a postmodern children's book, The "Three Pigs" by David Wiesner (2001). The students came to the project from basal-based direct instruction, and here they were offered a more constructivist opportunity to engage with a…

If you are a teacher of grades K-6, you may be asking, "Should I teach grammar in my classroom on a daily basis? How would I go about doing this? And how can I teach grammar so it isn't boring to my kids?" In "Grammar Matters," Lynne Dorfman and Diane Dougherty answer these questions and more. Using mentor texts as the…

Some statisticians have pointed out that the field of statistics essentially exists to study the variability seen in everyday life. Because variability is so foundational, the "Guidelines for Assessment and Instruction in Statistics Education" (GAISE 2007), published by the American Statistical Association (ASA), recommend that teachers…

The purpose of this two-year observational study was to determine if the use of technology and intervention groups affected fourth-grade math scores. Specifically, the desire was to identify the percentage of students who met or exceeded grade-level standards on the state standardized test. This study indicated possible reasons that enhanced…
