Numerical Indices Four in a Row – 38 Levels, 380 Worksheets + Answers

Make numerical indices easier to teach across a genuinely mixed-ability class with the complete Four in a Row collection. This substantial print-and-go bundle contains all 38 carefully sequenced levels and all 10 versions of every level: 380 differentiated games, each with its own question list and complete answer page. The progression begins with repeated multiplication and positive powers, then develops reciprocals, negative indices, roots, fractional indices and exact mixed calculations.

The 38-step ladder gives pupils an accessible entry point while retaining a demanding GCSE ceiling. Discrete levels isolate one new mathematical structure; local consolidation levels revisit the immediately preceding cluster; full consolidation levels bring earlier knowledge back deliberately. This makes it practical to place different pupils on different levels in the same lesson without giving the class visibly different activities.

Question types include writing repeated factors as powers; evaluating positive, negative and fractional powers; finding reciprocals; connecting roots with fractional indices; interpreting negative bases accurately; and completing exact calculations using related common bases.

WHAT IS INCLUDED

HOW FOUR IN A ROW WORKS
Pupils answer a question, locate the matching value on the board and claim that square. The aim is to connect four squares horizontally, vertically or diagonally. The familiar game structure creates a reason to calculate accurately while preserving substantial independent practice. It works well for paired competition, individual retrieval, intervention, cover work, revision, homework or a purposeful lesson finish.

WHY TEACHERS FIND IT USEFUL
• One recognisable activity can run across a mixed-ability room.
• The levelled structure supports precise differentiation without changing the basic classroom routine.
• Ten versions support repeated practice, parallel groups and reduced copying.
• Separate question lists keep the board uncluttered and make checking straightforward.
• Full answers support self-marking, peer assessment and rapid teacher feedback.
• Carefully varied questions build fluency rather than rehearsing one superficial template.

The resource uses UK mathematical language and has been mathematically validated, pagination checked and visually audited. Every board contains 36 definite responses. Equivalent numerical answers are controlled, adjacent duplicate answers are avoided, and version-to-version variation is audited. The result is a professional classroom resource that combines the motivation of a game with the depth and discipline of well-designed deliberate practice.
