Integers. Integer Games.
I just love grid puzzles and students do too. What is beneficial about using grid puzzles in the classroom is all students are simultaneously engaged. I have students complete the puzzles in pairs. These puzzles cover the 4 integer operations separately and then in mixed practice. They are designed to be a quick activity at the beginning of class to be used as formative assessment. The questions are selected to encourage mental computation. In my own classroom, I award the first 6 or 7 groups done with a small treat. To facilitate a check for accuracy at a glance each puzzle is designed with a message. I cut the puzzles out and keep in envelopes for year to year. It saves on paper and prep. Just make sure the students put all the pieces back in. The grid is 4 by 4 so 24 questions are included. Puzzles are provided for addition, subtraction, multiplication, division, mixed practice for integers and order of operations with whole numbers.
