Subtraction L22 Four in a Row | Standard Form With Positive Powers is a printable subtraction game from a structured 26-level progression, designed to build fluency in subtracting large numbers written in standard form.

This resource gives pupils focused practice in subtracting numbers written in standard form with positive powers of ten. Pupils must align or convert powers correctly, subtract the coefficients accurately and ensure that the final answer is written in valid standard form.

Pupils answer the calculations and try to connect four correct answers in the grid. The game format makes repeated standard-form practice more engaging while retaining the need for careful mathematical working.

This is one individual consolidation level from the wider 26-level Subtraction progression. It transfers earlier place-value and decimal subtraction skills into scientific notation and prepares pupils for calculations involving negative powers.

The progression is designed so that the notation becomes more advanced while subtraction remains the central skill. Pupils must understand the values represented by the powers rather than treating them as decorative symbols.

This individual Four in a Row resource is useful for:

starter activities
retrieval practice
homework
tutoring
cover lessons
paired work
small-group practice
KS4 number revision
GCSE Foundation and Higher practice

The game format adds motivation and pace, while pupils build confidence with coefficient subtraction, powers of ten and standard-form normalisation.

This resource is sold individually as one level from the full 26-level Subtraction Four in a Row progression.
