I created this printout to help students understand how to use Function/Input Output Tables with equations. There are tables with missing amounts, so the student must determine the rule and then the missing amounts. There is a guide with think aloud questions to help the students understand how to write an equation using the table. There is also an empty table for the student to create his/her own table with its own rule. This can be used in pairs, groups or individually. It has been helpful to my students in the past. The tables on this sheet have rules that apply to multiplication and addition.
