Keep your class calculators organized and in good condition. You can use a hanging sentence-strip pocket holder to do this. Write the names of all of your students on small strips of tagboard and place them alphabetically in the pockets on the chart. Place a calculator behind each name card. You may want to number the calculators as well and have a matching number on the back of each name card. When it is time to use the calculators, you can have helpers hand them out. This way you can keep track of them as well as ensure that students are not always using them for all of their math calculating.
