This is a great printable activity for students who are working on future, present, and past tenses. 6 pages (33 total) of tense discrimination are included. Present tenses include singular and plural present progressive (is/are verb+ing) and singular and plural present tense "-s" (walk versus walks). Past tense includes both regular and irregular forms.
An extension activity is included for students to generate all 3 tenses on their own and then use them in written sentences.
