Science learning often involves creating abstract representations and models of processes that we are unable to observe with the naked eye. Learn more about visualizing, representing, and modeling to aid struggling learners.
ALMA'S WAY follows 6-year-old Alma Rivera, a proud, confident Puerto Rican girl who lives in the Bronx with her family among a diverse group of close-knit friends and community members. In every episode, It aims to model self-awareness, self-advocacy, social awareness, cultural competency and responsible decision-making -- encouraging kids to generate and value their own ideas and questions. It celebrates and explores the thinking process -- Alma's "way" is to think things through. As she shares her observations and feelings and works through challenges, she speaks directly to young viewers, offering them a window into her everyday life. This Collection includes: Video (10), Media Gallery (3), Webpage (2) for Grades PreK-K, K-2 , Resources in Spanish (3).
Students will practice counting from 1-30 and having one-to-one correspondence with objects for these numbers. Also, they will practice finding patterns on a hundreds chart. This lesson includes a detailed plan, videos of students participating in a counting chain, and a printable ten frame worksheet.
In the NGSS, one of the performance expectations is for the children to develop a model to represent the shapes and kinds of land and bodies of water in an area. In the science practices, the children also must develop and use models. This lesson will help them understand that process. Video clips of the student's explaining their models are included.
Using a mathematical model, students will be able to visually see the process of how to multiply a fraction by a whole number to find its product in order to gain a deeper understanding to ultimately be able to do it on their own.
A lesson focused on subtracting mixed numbers using fraction strips and an interactive fraction pad.
Find animated diagrams that describe both eukaryotic cells and prokaryotic cells. There are models for animal, plant, and bacteria cells.
In this context-setting lesson, students will run and collect data from a simple simulation in Sprite Lab. After running the simulation multiple times, students will have an opportunity to predict how changing a variable in the simulation might impact the outcome and test that hypothesis. This lesson aligns to national Computer Science standards from CSTA.
This lesson combines skill-building around events with a mini-project where students get to build their own computer simulation in Sprite Lab. Students will study the simulation to understand how quickly a virus can spread and what can be done to slow it down. This lesson aligns to national Computer Science standards from CSTA.
In this exploratory lesson, students will train a machine learning model by classifying fish and other objects. This lesson aligns to national Computer Science standards from CSTA.
This online interactive module of 10 pages or frames integrates textual information, 3D molecular models, interactive molecular simulations, and embedded assessment items to guide students in understanding the copying of DNA base sequences from translation to transcription into proteins within each cell. The module divides the exercises in to Day 1 and Day 2 time frames. Teachers can view student assessment responses by assigning the module within a class created within the Molecular Workbench application. This Java-based module must be downloaded to each computer.
Engineers use a series of steps called the design process to solve a problem. In this resource, featuring video segments excerpted from DESIGN SQUAD, watch teams of kids work through each of the five steps of the design process: 1) identify the problem; 2) brainstorm; 3) design; 4) build, test, evaluate, and redesign; and 5) share solutions.

The WebMuseum offers a biography of Georges Seurat (1859-1891 CE), known for his creation of the Pointillism technique of 19th century neo-impressionist painting. Content includes numerous samples of his work, as well as full descriptions of each piece.
How do animals digest food? Animal nutritionists determine feed rations for livestock, zoo animals, and pets related to their dietary needs but also their digestive systems. This unit will make a connection between soybean used as high protein feed and the types of digestive systems in animals. This unit features 3 lessons and 7 files. Lessons are aligned to NGSS.
A mathematics tutorial that allows you to interactively learn and manipulate the slope and intercepts of a line.
Discover different types of compounds such as binary covalent, binary ionic, binary acids, and oxyacids. Explore links that give information about writing names and formulas for different compounds.
This excellent high school physics tutorial from The Physics Classroom investigates motion formulas using several problem-solving strategies including diagrams, equations, and lists.

Prior Knowledge
Students should be able to:
Write and evaluate simple expressions that record calculations with numbers.
Use parentheses, brackets, or braces in numerical expressions and evaluate expressions with these symbols.
Interpret numerical expressions without evaluating them.
Lesson Flow
Students learn to write and evaluate numerical expressions involving the four basic arithmetic operations and whole-number exponents. In specific contexts, they create and interpret numerical expressions and evaluate them. Then students move on to algebraic expressions, in which letters stand for numbers. In specific contexts, students simplify algebraic expressions and evaluate them for given values of the variables. Students learn about and use the vocabulary of algebraic expressions. Then they identify equivalent expressions and apply properties of operations, such as the distributive property, to generate equivalent expressions. Finally, students use geometric models to explore greatest common factors and least common multiples.
Lesson OverviewStudents use a geometric model to investigate common multiples and the least common multiple of two numbers.Key ConceptsA geometric model can be used to investigate common multiples. When congruent rectangular cards with whole-number lengths are arranged to form a square, the length of the square is a common multiple of the side lengths of the cards. The least common multiple is the smallest square that can be formed with those cards.For example, using six 4 × 6 rectangles, a 12 × 12 square can be formed. So, 12 is a common multiple of both 4 and 6. Since the 12 × 12 square is the smallest square that can be formed, 12 is the least common multiple of 4 and 6.Common multiples are multiples that are shared by two or more numbers. The least common multiple (LCM) is the smallest multiple shared by two or more numbers.Goals and Learning ObjectivesUse a geometric model to understand least common multiples.Find the least common multiple of two whole numbers equal to or less than 12.
