Number pattern problems using only subtraction operations, but with gaps at beginning or middle of the series.
The subtraction number patterns on these worksheets require students to supply missing values at the beginning or middle of the number sequences. This requires a student to understand the rule for the pattern in reverse as well as forward, and can help provide the skills to transition easily between addition patterns and subtraction patterns. These are more comprehensive problems suitable for regular practice once the basic number pattern concepts are well understood.
