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.
