Intermediate Arithmetic
Start with Place value, Addition & subtraction and Multiplication & division. Each module explains the idea, shows a worked example and ends with a short project, so Arithmetic becomes something you can do rather than something you have only read about.
Modules: Foundations of Place value · Core methods in Addition & subtraction · Applying Multiplication & division
- Place value: This module treats Place value as a tool: the question it answers, what it assumes, and what a correct use of it looks like in Arithmetic.
- Putting place value to work: Place value is introduced from first principles, with the few terms you actually need and an example that shows how the idea behaves in practice.
- Checking your understanding of place value: This module treats Place value as a tool: the question it answers, what it assumes, and what a correct use of it looks like in Arithmetic.
Project: Write a one-page explanation of Place value in your own words, with an example you chose yourself, and test it against the module checklist.
