Teacher Resources for Index Laws
Teach index laws — also called the laws of exponents or exponent rules — to Years 8-10 with a complete set of lesson plans, worksheets, practice questions and assessments. Each resource builds students up from multiplying and dividing powers through to zero, negative and fractional indices, with worked examples teachers can adapt to their own classroom pace.

What’s Included in the Resources for Index Laws?
🔥Curriculum Aligned
Aligned to the Australian Curriculum v9.0 (and mapping cleanly to US laws-of-exponents standards), the index laws set gives teachers a sequenced path through the seven main rules: product, quotient, power of a power, power of a product, power of a quotient, zero index and negative index. Each rule has a worked example, a guided practice block and an extension question for early finishers.

🌍 Differentiated for Students
Show students where index laws actually appear outside the classroom — compound interest, scientific notation, exponential growth, half-life decay and the way memory or storage scales in powers of two. These contexts make abstract rules concrete and give every lesson a clear answer to "when will I use this?"
💡Incredible Teacher Resources
Practice questions move from single-rule warm-ups (simplify a⁵ × a³) to multi-step problems that combine product, quotient and power-of-a-power rules with negative and fractional indices. Each set is scaffolded so teachers can set the same task to a mixed-ability class and extend stronger students without re-planning.

Interactive Resources
Practice Questions
Tutero’s index laws resources cover every rule a Year 8–10 (Grade 8–10) student needs: the product rule (a^m × a^n = a^{m+n}), quotient rule (a^m ÷ a^n = a^{m-n}), power of a power ((a^m)^n = a^{mn}), zero index (a⁰ = 1), negative index (a^{-n} = 1/a^n) and fractional index (a^{1/n} = the n-th root of a). Each rule comes with a teaching slide, a worksheet and an assessment item.
Structured Solutions
Differentiated Questions
Each question set includes a clean answer key with full working, so teachers can mark quickly or hand it to students for self-checking. Common student errors (dropping the base, multiplying when they should add indices, forgetting that a⁰ = 1) are flagged inline so teachers know what to watch for.
Real-World Applications
Engaging Exercises
Real-world tasks ask students to use index laws to compare population growth rates, work out compound interest over different terms and re-write numbers in scientific notation. Each task is short enough to slot into a single lesson and structured so students can show full working.

Step-by-Step Lessons for Introducing Index Laws
Each lesson introduces one index law at a time, with a worked example, a guided practice block and a short formative check. The sequence starts with the product and quotient rules (multiplying and dividing powers with the same base), then power of a power, then the special cases that students typically find hardest — the zero index, negative indices and fractional indices. Slides, teacher notes and student handouts are aligned so teachers can run the lesson straight from the pack or rearrange it to match their own scheme of work.
Advanced Question Sets for Mastery of Index Laws
The advanced sets combine multiple index laws in a single question and bring in negative bases, surds and algebraic terms. Students are asked to simplify, evaluate and rearrange expressions, with stretch problems that lead into work on exponential equations and logarithms. Teachers can use these as homework, as a senior-class review of indices before logs, or as a differentiated extension when the main task is finished.
Hands-On Assessments and Projects to Explore Indices in Real Life
The assessment pack pairs short-answer questions on each individual law with longer real-world tasks: comparing the growth of two investments at different compound rates, modelling exponential decay in a half-life problem and converting between standard form and decimal notation in scientific contexts. A marking rubric and full worked solutions are included, so teachers can use the same pack as a low-stakes check or as a summative end-of-topic assessment.
