Frequently asked questions

What's on a Grade 8 simple interest worksheet?
Each pack has up to 12 questions per page with a matching answer key, tuned to Grade 8, with beginner, intermediate, and advanced options so a teacher, tutor, or parent can match the learner's level.
What grade is simple interest taught in?
Simple interest is introduced in Grade 8 as part of the financial literacy strand, building on the percentage skills learned in Grades 6-7, then continues through Grades 9-11.
What's the difference between simple and compound interest?
Simple interest is always calculated on the original principal. Compound interest is calculated on the growing balance (principal plus previously earned interest), so it grows faster over time.
