Overview:

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.

One of the best parts of teaching conditionals is that students already understand the concept from their everyday lives.

This lesson merges computer science into the real world by building off of students ability to tell if a condition is true or false. Students will learn to use `if` statements to declare when a certain command should be run, as well as `if/else` statements to declare when a command should be run and what do run otherwise. Students may not recognize the word conditionals, but most students will understand the idea of using "if" to make sure that some action only occurs when it is supposed to.

Students will be able to:
- define circumstances when certain parts of a program should run and when they shouldn't.
- determine whether a conditional is met based on criteria.
- traverse a program and predict the outcome, given a set of input.

Content Standard(s):
 Digital Literacy and Computer Science DLIT (2018) Grade: 3 2) Analyze a given list of sub-problems while addressing a larger problem. Example: Problem - making a peanut butter sandwich; sub-problem - opening jar, finding a knife, getting the bread. Problem - design and share a brochure; sub-problem - selecting font, choosing layout. Digital Literacy and Computer Science DLIT (2018) Grade: 3 3) Explain that different solutions exist for the same problem or sub-problem. Example: Multiple paths exist to get home from school; one may be a shorter distance while one may encounter less traffic. Digital Literacy and Computer Science DLIT (2018) Grade: 3 4) Examine logical reasoning to predict outcomes of an algorithm. Digital Literacy and Computer Science DLIT (2018) Grade: 3 23) Implement the design process to solve a simple problem. Examples: Uneven table leg, noise in the cafeteria, tallying the collection of food drive donations.
