Coders use the start on green flag block to create a silly dance party using motion blocks. The purpose of this project is to introduce young coders to adding sprites in code and triggering algorithms with the green flag in ScratchJr.

We can use de Casteljau's algorithm to calculate curves using any number of points.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"3D-printed with microscale precision, these tiny architectural marvels could be the key to making high-temperature ceramics less vulnerable to fracture. The implications could span across the numerous areas these materials are used, from aerospace to tissue engineering. The blueprint for these hardy structures is reported in the Journal of Materials Research Volume 33, Issue No. 3, earning honors as the 2018 JMR Paper of the Year. Researchers built the miniature trusses layer by layer using a technique called projection microstereolithography. In this process, a UV-light pattern is scanned across a polymer bath composed of photo-active ceramic building blocks. The silicon-based polymer solidifies at every point traced by the UV beam. Subsequent heating in a high-temperature furnace activates the polymer structures, baking off volatile organics, to produce silicon oxycarbide structures. The team then put these structures to the test..."

"When modern 3D printing was invented in the early 1980s, few could have predicted the influence it has today. At no other time in history has it been this easy to transform a sketch into the real thing. And while that feat has proven immensely useful for constructing complex machines, it is unlikely more meaningful anywhere else today than in the field of biomedicine. With the ability to churn out standard or custom prosthetics, devices, and even test models, the 3D printing of biomaterials is revolutionizing medical care. One of the greatest conveniences afforded by biomedical 3D printing is the ability to manufacture parts on demand. Common load-bearing prosthetics, such as those for knee or hip replacements, no longer have to be built in bulk and benched before use. Virtually stored print files can be called upon and processed into parts as soon as they are needed in the clinic, with the printing material and method suited to the part’s function and placement..."

Let's take a closer look at the weights used during subdivision. Do we have to be careful when selecting weights?

Learn how honey bees work together as a hive to provide for their own needs while pollinating our planet's flowers!  This lesson includes learning objectives, material and resource lists, background information, activities, reading selections, writing assignments, a game, assessments, and support documents. See the Educator's Guide for more video links and recommended readings. 

Let's look more closely at how light bounces when it strikes an object. We'll cover reflected and refracted rays.

This resource was created by Jeanine Figueroa, in collaboration with Dawn DeTurk, Hannah Blomstedt, and Julie Albrecht, as part of ESU2's Integrating the Arts project. This project is a four year initiative focused on integrating arts into the core curriculum through teacher education, practice, and coaching.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: A small square is a square unit. What is the area of this rectangle? Explain. What fraction of the area of each rectangle is shaded blue? Name the frac...

This task is related to Sub Claim C: Elapsed Time. Students are adding and subtracting time intervals on a number line. Standard 3.MD.1

This task challenges students to find the area of different sections of a garden and the entire garden. With missing lengths and widths, the students are challenged to apply computation skills to finding missing measurements.

This task requires students to find the area and perimeter of a rectilinear figure and model their thinking through multiple equations. This task relates to the Common Core State Standards: 3.MD.C.7d, 3.MD.D.8, and 3.OA.D.8.

This task requires students to find the area of a rectilinear figure and model their thinking through multiple equations. This task relates to the Common Core State Standards: 3.MD.C.7d and 3.OA.D.8.

This is a concrete referent reasoning task for Grade 3. Students need to use the diagram to find the information to find the area of a rectilinear figure. This is a task that would be a good starting point for solving problems for this standard.

A task related to standard 3.MD.7d, additive area of rectilinear figures. Students find the area of the parts of a pool to ultimately find the area of the entire pool.
