Teachers can use ExploreLearning Gizmos as a demo projected in front of the class, but Gizmos are best used when placed right in the hands of the students. After setting up a teacher account, educators go to their Teacher Homepage, where they can create classes, assign individual Gizmos, and view assessment results. Teachers can select Gizmos aligned to the Next Generation Science Standards and Common Core State Standards for math. Gizmos are also organized according to popular textbooks and curriculums such as FOSS Science.
Each Gizmo has support materials including Lesson Plans, Vocabulary Sheets, Teacher's Guides, and editable Student Exploration Sheets. Each activity also ends with an online assessment, the results of which are available immediately to teachers and students. The ExploreLearning community allows teachers to share worksheets and lessons that they have created using the Gizmos.Continue reading Show less
It's difficult to describe the entire array of interactive simulation tools (called Gizmos) that ExploreLearning makes available on this site. Arranged by curriculum, topic, or textbook, these little applications explore hundreds of concepts that students learn in elementary, middle, and high school mathematics and science. From number sense to algebra and from biology to physics, there are enough tools here for students to try a different one each week for every school year.
Each Gizmo comes with extensive support through the site and printable resources to help with deployment. The Exploration Sheet includes some questions that activate prior knowledge and others that allow students to record their learning during an activity. An assessment is administered at the end of each Gizmo to measure student learning. All of these are of high quality and rigorous enough to be useful in any classroom.Continue reading Show less
ExploreLearning Gizmos allow individual students to experiment and build their own understanding of the concepts involved. Many are conducive to classroom demonstrations for a larger group, but this method loses the magic that comes from kids tweaking the settings of a simulation to see what happens. For example, the Archimedes Principle Gizmo is perfect for teaching the idea of buoyancy and displacement to middle school students. A student can learn a lot by adjusting the size of a "boat" and then adding mass until it sinks, observing how such factors affect whether a boat floats.
Gizmos embody the three-dimensional learning called for by the Next Generation Science Standards. Students are engaged in Science and Engineering Practices such as analyzing data, while they also learn content. Woven throughout the Gizmos are Cross-Cutting Concepts such as cause and effect and systems and scale. Simulations bundled with a few assessment questions help kids practice for the tech-enhanced items now appearing on many standardized science tests.Continue reading Show less
Key Standards Supported
Expressions And Equations
Write, read, and evaluate expressions in which letters stand for numbers.
Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.”
Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 × 108 and the population of the world as 7 × 109, and determine that the world population is more than 20 times larger.
Interpreting Categorical And Quantitative Data
Represent data with plots on the real number line (dot plots, histograms, and box plots).
Measurement And Data
Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
Number And Operations In Base Ten
Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.
Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.
Number And Operations—Fractions
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions
Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.
Statistics And Probability
Display numerical data in plots on a number line, including dot plots, histograms, and box plots.
Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book.
Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.
Vector And Matrix Quantities
(+) Recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes (e.g., v, |v|, ||v||, v).
