Hear your students "roar" these math words with ease after participating in these activities! This unit includes posters, graphic organizers, card games, and sorts that focus on differentiating between "addition" words and "subtraction" words when reading word problems. Students will use the "Additoro Rex" and the "Subtractosaurus" to help them remember which words go with which operation. These activities can span throughout the year as lessons, math stations, or supplemental activities. Have fun!
