Print by grade
-
4th grade
Input-output tables for fourth grade use one-step rules (add 7, subtract 4, multiply by 3) with a couple of Out values missing from each table. Your child applies the stated rule down the column, a first taste of how functions behave.

5th grade Core grade
Each print is a different sheet with its own answer key. You don't need to sign up.
Fifth grade tables keep the one-step rules but flip the question: some tables state the rule and hide values, others show every pair and ask your child to write the rule in words, like multiply by 3.
-
6th grade
In sixth grade the tables switch to x and y, and rules read like equations: y = 3x or y = 3x + 2. Your child completes tables and writes two-step rules, dependent-variable thinking that runs straight into algebra.
