S'more Grammar Games includes a game for both irregular plurals and irregular verb tenses. Each game is themed with the campfire and s'more themes. In the irregular verbs game, students create sentences for irregular past, present and future tense of verbs. They must collect all three to make a s'more! The irregular plural games is played using a campfire for each student. They take turns drawing marshmallows on a stick. Each stick names the singular form and students need to create a sentence for the plural form.
