This activity has 21 problems for students to punch into their calculators. Each slide will ask them a theme question. Then, they will enter each bullet of information into their calculator. Often a bullet will ask them to apply math skills to know what to enter into their calculator. After entering each step, the student pushes the equal button, turns the calculator upside down and it will reveal the answer to the opening question. Students love doing these problems and beg for more. I often used these for a fun morning work activity and just set it up on a classroom computer for students to complete. They could also be printed and laminated for math centers. Be sure to look for set 2 also!
