Math and teaching courses

These courses make everyday maths automatic and show teachers how to put Excel to work in the classroom. Each lab is a short, realistic problem in a spreadsheet that checks your answer instantly, so you practise until the method sticks instead of reading a worked example and moving on.

Business Math Essentials covers percentages, ratios, simple and compound interest, discount and markup chains, weighted averages, unit conversions, solving for an unknown and growth with the rule of 72. Probability & Combinatorics for Decisions covers counting, permutations and combinations, conditional probability, Bayes' theorem, expected value and the binomial, Poisson and normal distributions. Algebra & Functions with Spreadsheets covers expressions, linear and quadratic functions, systems of equations, exponential growth, logarithms, inequalities and a numerical root finder. Excel for Teachers builds a weighted gradebook, drops the lowest score, assigns letter grades, summarises class results, curves a test, tracks attendance and runs an item analysis. The courses suit adult learners refreshing their maths, school students, students in business and vocational programmes, and teachers who want reliable gradebooks and class analytics without paying for extra software.

Frequently asked questions

Is this course suitable if I am bad at maths?

Yes. Business Math Essentials starts with percentages and ratios and explains every step. The spreadsheet does the arithmetic, so you can concentrate on the method.

Can teachers use the gradebook for real classes?

Yes. Excel for Teachers builds a weighted gradebook, letter grades and class statistics with formulas you can rebuild in Excel or Google Sheets for your own classes.

Is probability covered without heavy theory?

Yes. Each topic starts from a business question, such as a quality inspection or an alert that goes off, and the lab calculates the answer with ordinary spreadsheet functions.
