Create your own calculator race sheet... What to do: This activity allows students to become comfortable with using a calculator- scientific/non-scientific. Students should be handed the worksheet and simply follow the instructions on it! The idea is for them to race through the tasks choosing when to use a calculator... Variations:
Hand students subtly differentiated questions based on their current levels.
Ask some students to complete the activities using mental arithmetic only!
