Model daily processes by creating and following algorithms (sets of step-by-step instructions) to complete tasks.

Develop programs with sequences and simple loops, to express ideas or address a problem.

Decompose (break down) the steps needed to solve a problem into a precise sequence of instructions.

Debug (identify and fix) errors in an algorithm or program that includes sequences and simple loops.

Create programs that include sequences, events, loops, and conditionals.

Decompose (break down) problems into smaller, manageable subproblems to facilitate the program development process.

Test and debug (identify and fix errors) a program or algorithm to ensure it runs as intended.

Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.

Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.

Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
