Type: Lesson/Unit Plan

Overview:

Now that students know how to layer their loops, they can create so many beautiful things. This lesson will take students through a series of exercises to help them create their own portfolio-ready images using Anna and Elsa's excellent ice-skating skills!

In this series, students will get practice nesting loops while creating images that they will be excited to share. Beginning with a handful of instructions, students will make their own decisions when it comes to creating designs for repetition. They will then spin those around a variety of ways to end up with a work of art that is truly unique.

Students will be able to:
- describe when a loop, nested loop, or no loop is needed.
- recognize the difference between using a loop and a nested loop.
- break apart code into the largest repeatable sequences using both loops and nested loops.

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 28) Develop, test, and refine prototypes as part of a cyclical design process to solve a complex problem. Examples: Design backpack for a specific user's needs; design a method to collect and transport water without the benefit of faucets; design boats that need to hold as much payload as possible before sinking; design models of chairs based on specific user needs. Unpacked Content Evidence Of Student Attainment:Students will: develop prototypes as part of a cyclical design process to solve a complex problem. test prototypes as part of a cyclical design process to solve a complex problem. refine prototypes as part of a cyclical design process to solve a complex problem.Teacher Vocabulary:develop test refine prototypes cyclical design processKnowledge:Students know: how to use the design process to solve a complex problem. strategies for creating a prototype as part of a cyclical design to solve a problem. strategies for testing and refining prototypes as part of a cyclical design process to solve a complex problem. characteristics of a cyclical design process.Skills:Students are able to: develop, test, and refine prototypes as part of a cyclical design process to solve a complex problem.Understanding:Students understand that: developing, testing, and refining are necessary steps in creating an effective prototype.
