This article provides a brief discussion of the importance of teaching students to analyze data and representations of data as well as two resources that can help teachers implement these strategies into their instruction.

A set of lessons that covers most of 3.1 (Core Knowledge). Teachers would need to add a solution design activity to cover 3.1.3. This unit has students evaluate design solutions, but not design their own.

The COVID-19 Pandemic is a clear example of how science and society are connected. This unit explores how different communities are differentially impacted by the virus through the lens of historical inequities in society. In the context of decisions their families make, students explore the basics of how the virus affects people, and design investigations to explore how it spreads from person to person, and what we can do to prevent that spread.

This lesson demonstrates how conditionals can be used to tailor a program to specific information. We don’t always have all of the information we need when writing a program. Sometimes you will want to do something different in one situation than in another, even if you don't know what situation will be true when your code runs. That is where conditionals come in. Conditionals allow a computer to make a decision, based on the information that is true any time your code is run.
Up until this point students have been writing code that executes exactly …
Up until this point students have been writing code that executes exactly the same way each time it is run - reliable, but not very flexible. In this lesson, your class will begin to code with conditionals, allowing them to write code that functions differently depending on the specific conditions the program encounters.

By the time students reach this lesson, they should already have plenty of practice using `repeat` loops, so now it's time to mix things up.
_While loops_ are loops that continue to repeat commands while a condition is met. `While` loops are used when the programmer doesn't know the exact number of times commands need to be repeated, but does know what condition needs to be true in order for the loop to continue repeating. For example, students will be working to fill holes and dig dirt in Farmer. They will not know the size of the holes or the height of the mountains of dirt, but the students will know they need to keep filling the holes and digging the dirt as long as the ground is not flat.

In this lesson, students will learn about `until` loops. Students will build programs that have the main character repeat actions `until` they reach their desired stopping point.
Students will practice `while` loops, `until` loops, and `if / else` statements. …
Students will practice `while` loops, `until` loops, and `if / else` statements. All of these blocks use conditionals. By practicing all three, students will learn to write complex and flexible code.
