Wednesday, September 5, 2018

Today in class:

Please work in your assigned groups. Please manage your time wisely. From the beginning of class, you have 15 minutes to review the text, example flowchart ("Hey Jude"), and link for flowchart symbols and meanings, and project instructions and brainstorm to choose your topic for your flowchart. For the next 15 minutes, work with your groups to complete your flowcharts. For the next 10 minutes, exchange your flowchart with another group and provide written feedback, noting both strengths, weaknesses, and suggested improvements. *Your group will be graded not only on your flowchart, but also on the feedback you provide the other group, so please be sure to put all group member names on your project as well as the feedback you provide the other group. For the last 10 minutes of class, we will read our text "CODING SKILLS: Encryption." 

This means second hour will exchange projects for review at 9:24 a.m. and sixth hour will exchange projects for review at 1:46 p.m.

Please thoroughly review the instructions below before beginning. 

Review the text on flow patterns and flow charts. Discuss the example flowchart illustrating how to sing "Hey Jude" and how it could be better. It is flawed. Then, as a group, create a flowchart illustrating a process, such as making a great peanut butter and jelly sandwich. (Use the explanation of common flowchart symbols and meanings found at https://en.wikipedia.org/wiki/Flowchart#Building_blocks to choose your symbols.) 

Each flowchart must meet the following requirements:

-- Must have a least six steps. May have more. 

-- Must use sequencing, selection, and iteration. Must use either a definite loop or an indefinite loop. Sequencing, selection, iteration, and definite or indefinite loop must be labeled within the chart.

-- You may bring examples to illustrate your flowchart on Friday. Some suggestions during sixth hour yesterday were how to bake brownies, how to make pizza, getting ready for school, and how to apply makeup. Enjoy!

Your flowcharts and feedback to the other group are due by the end of the hour.

Tuesday, September 4, 2018

Today in class:

-- We studied vocabulary set two on Quizlet and took the accompanying test.

-- We studied vocabulary three on Quizlet.

-- We read the section on Flow Patterns in our online text and discussed flowcharts.

-- Reading the section on Algorithms was assigned as homework.

-- Sixth hour brainstormed ideas for process flowcharts. Second hour will do this Wednesday, and both classes will complete the flowchart project.
