Description

Ask any working adult which school skill they use most and a surprising number will say the spreadsheet. Almost none of them were ever taught it.

Cells & Secrets: The Art of Spreadsheets is a self-paced spreadsheet class for high school that fixes that. With Anna Knaub, students work through intro basics and spreadsheet operations, formulas and functions, advanced functions, data management, charts and graphs, conditional formatting, data validation and protection, PivotTables, advanced charting, macros, collaboration and sharing, and advanced data analysis.

Every week brings a hands-on project with a real purpose behind it: tracking expenses, managing a budget, organizing a project, reading a trend.

Nothing needs purchasing. Your student needs access to Google Sheets or Excel and a willingness to become the person in the room who can make the numbers behave. It pairs well with Entrepreneurship I and II, Personal Finance, or Biz Talk.

Anna Knaub is a licensed Pennsylvania teacher and homeschool evaluator who studied Medieval and Renaissance literature and has taught for over twenty years.

“I have grown in my reading analysis and writing skills, especially poetry. I thoroughly enjoyed the environment you created.”
— A TNA Student, on British Literature and Composition

  1. Kathy (verified owner) –

    My boys INHALED this class! Ms. Knaub makes spreadsheets really engaging and fun. The workload was light and the concepts applicable and memorable. She uses Google Sheets (free) so no software purchase was necessary. My husband was talking about a spreadsheet he was making for work and the boys chimed in, talking about some of the functions they had learned in class and how they could be useful. I’d like to put my request in for an advanced class!
