Mixed word problems, or number stories, are a challenge in first grade and second grade. Knowing whether a word problem requires addition or subtraction can be difficult. This pack was created to help students to identify key words and determine which operation they should use. As they complete the story problems, they also will get plenty of practice with addition and subtraction facts within twenty.
The resource includes:
• four scoot games
• recording sheet
• two interactive notebook pages to record key words
The word problems included have a wide variety of addition and subtraction situations represented. An answer key is also included.
In my classroom, we complete the addition scoot on day one and go over the answers as a class. I laminate the story problem strips so we can display them under our document camera and use an expo marker to highlight the addition key words. I list the key words we come across on the board as we go. Students then add the words to their addition keys and paste them into their interactive notebooks.
We repeat this process on day two with the subtraction scoot problems. After that, the mixed addition and subtraction sets can be used in a whole group or as a math center activity. Students can use their interactive notebook pages to help them to determine which operation to use as they work.
This pack addresses the following first and second grade Common Core Standards:
*1.OA.A.1: Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
*1.OA.A.2: Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
*2.OA.A.1: Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
It could also be used as review for third graders.
