Choose the operations and the amount of support
Choose by the learner’s current skills. Mixing operations adds the task of recognizing a sign before choosing a method, even when the individual numbers are familiar.
The preview shows the first student page. Downloads contain the complete worksheet; the version with answers adds a separate key with matching problem positions. More spacious written-method practice may use several pages.

Teaching notes
Make the practice count
- Every symbol uses two decimal places here, including yen. This is symbol-based decimal practice, not a claim about a currency’s usual cash denominations.
- The chosen integer width is a maximum; select zero for amounts below one.
- Keep the currency symbol separate from the digit columns.
