Subtraction L23 Four in a Row | Standard Form With Negative Powers is a printable subtraction game from a structured 26-level progression, designed to develop fluency with very small numbers in standard form.

This resource gives pupils focused practice in subtracting numbers written in standard form with negative powers of ten. Pupils must understand the place value represented by negative indices, align or convert powers correctly and write final answers in valid standard form.

Pupils answer subtraction questions and try to connect four correct answers, creating pace and engagement without reducing the mathematical challenge.

This is one individual consolidation level from the wider 26-level Subtraction progression. It builds on standard form with positive powers and extends the same subtraction process to quantities smaller than one.

The rationale behind the progression is that pupils should first secure standard-form structure with large numbers before applying it to negative powers. The surrounding notation becomes harder, but subtraction remains the central skill.

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 improve their understanding of negative powers, coefficient arithmetic and standard-form notation.

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