Solving word problems is one of the most difficult tasks in math! Make this fun and engaging for your students with this easy, ready to use unit. Students will become detectives (and earn badges along the way) as they learn clues to help them determine if addition or subtraction is needed to solve the problems. Students are immersed in each type of word problem and engaged to discover much of the concepts on their own! In this unit you will get daily lesson descriptions, worksheets, clue sheets, sample problems and so much more! There is also a sorting activity and writing components throughout the lesson. Addition, subtraction, mixed operation and multi-step problems are all introduced in this unit with a final assessment to use at the completion of the unit. Choose to use this as a 3-4 week unit, or complete one lesson weekly to keep students constantly practicing problem solving (for a total of about 16 different lessons!). Answer sheets, printables, badges and so much more included!
