Alien Errors

Worksheet Description

Students read twelve silly sentences about aliens learning how to spell Earth words. Each sentence contains one incorrect -ed or -ing form that students must circle and repair. The examples include aliens floating through cafeterias, riding cupcakes, joining moon gyms, and mixing moon dust. Students write the correctly spelled word on the line below each sentence.

This worksheet helps students detect word-ending errors while reading complete sentences. The funny situations keep attention high, but students still need to study each root word and apply the proper spelling rule. Correcting the words also strengthens their understanding of whether the action happened before or is happening now. The activity improves proofreading, grammar, spelling memory, and sentence-level reading.

This worksheet is part of our adding -ed and -ing worksheet series.
