Coders use a variety of blocks in parallel to create simulations (e.g., dribbling a ball). The purpose of this short project is to apply previously learned understandings in order to simulate motion.

These lesson plans and activities were developed by Janine Darragh, Gina Petrie, and Stan Pichinevskiy and were previously located on the Reaching for English app. Created for K-12 English teachers in Nicaragua, the materials may be used and adapted for any country's specific context and needs.

Coders learn how to use the “go to page” blocks to create a multi-page story about a rainy day. The purpose of this project is to introduce coders to the “go to page” blocks and to apply previous understandings across multiple pages.

Coders use a variety of blocks and sprites to create a multi-page story about a day as a pirate. The purpose of this project is to reinforce the “go to page” blocks and to apply previous understandings across multiple pages.

Coders use the repeat block to repeat a silly dance for Scratch Cat using motion blocks. The purpose of this project is to introduce young coders to repeating algorithmic sequences in ScratchJr.

This lesson unit is intended to help teachers assess how well students are able to visualize two-dimensional cross-sections of representations of three-dimensional objects. In particular, the lesson will help you identify and help students who have difficulties recognizing and drawing two-dimensional cross-sections at different points along a plane of a representation of a three-dimensional object.

This Demonstration illustrates the concept of rotating a 2D polygon. The rotation matrix is displayed for the current angle. The default polygon is a square that you can modify.

This activity is designed for a primary classroom (outdoors & indoors) investigation where students collect and investigate soil samples and describe the soils, looking for similarities and differences. Students develop a method of recording the data colleted and can present the information gathered.

This week we will examine the concept of a function, a fundamental concept underlying all of modern mathematics. You’re undoubtedly already familiar with functions in an intuitive sense: a function is something which, given
an input, produces an output. But you’ve probably never seen the formal definition of a function as it relates to set theory, which is what we’ll look at this week.

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 aspects of the task and its potential use.

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: * Color the inside of all the triangles blue. * Color the inside of all the quadrilaterals red. * Color the inside of all the pentagons orange. * Color...

Next lets build a diagram that break rotation into smaller parts. The next exercise will give us a chance to build our understanding of this diagram.
