Type: Lesson/Unit Plan

Overview:

In this lesson, students will explore the creation of repetitive designs using variables in the Artist environment. Students will learn how variables can be used to make code easier to write and easier to read, even when the values don't change at runtime. This stage teaches the most basic use for variables, as a constant that reoccurs frequently in a program.

Students will be able to:
- assign values to existing variables.
- utilize variables in place of repetitive values inside of a program.

Content Standard(s):
 Digital Literacy and Computer Science DLIT (2018) Grade: 5 6) Create a working program in a block-based visual programming environment using arithmetic operators, conditionals, and repetition in programs. Unpacked Content Evidence Of Student Attainment:Students will: create a working program in a blockbased visual programming environment. create a program in a blockbased visual programming environment using arithmetic operators such as AND, OR, and NOT. create a program in a blockbased visual programming environment using conditionals such as IF, THEN, and/or ELSE. create a program in a blockbased visual programming environment using repetition or loops.Teacher Vocabulary:program block-based visual programming environment arithmetic operators conditionals repetitionKnowledge:Students know: how to create a working program in a block-based visual programming environment. reasons for using arithmetic operators, conditionals, and repetition in programs.Skills:Students are able to: create a working program in a block-based visual programming environment using arithmetic operators, conditionals, and repetition in programs.Understanding:Students understand that: arithmetic operators, conditionals, and repetition in programs make more operations possible and can reduce the complexity or length of code. Digital Literacy and Computer Science DLIT (2018) Grade: 5 7) Identify variables. Unpacked Content Evidence Of Student Attainment:Students will: identify variables in computing and other subject areas.Teacher Vocabulary:variableKnowledge:Students know: a variable is a factor in a program or problem that is likely to change. how to identify variables.Skills:Students are able to: identify variables.Understanding:Students understand that: variables are a part of an algorithm or problem that are likely to change. Digital Literacy and Computer Science DLIT (2018) Grade: 5 8) Demonstrate that programs require known starting values that may need to be updated appropriately during the execution of programs. Examples: Set initial value of a variable, updating variables. Unpacked Content Evidence Of Student Attainment:Students will: demonstrate that programs require known starting values that may need to be updated appropriately during the execution of programs.Teacher Vocabulary:starting value execution of programs initial value updating variablesKnowledge:Students know: that for a program to run properly, the starting value may need to be set when the program begins.Skills:Students are able to: explain a scenario in which starting value is important to a program. Understanding:Students understand that: programs require known starting values that may need to be updated appropriately during the execution of programs.
