Use this 10-page scavenger hunt to engage students in adding and subtracting decimals. Laminate, cut out and post the posters around the room. Students start at a random poster, work that problem, then look for the answer on a different poster. Students work until all 10 posters are complete.
Answer key and recording sheet included!
