# Algebra topics for elementary kids

Below are the elementary topics available for the category "Algebra" at Free Math Games.

These free math topics with audio offer a complete set of basic Algebra topics for elementary pupils (Kindergarten to 5th grade, ages 5 to 11). The Algebra category is divided into sub-categories such as "Equations", " Formulae: perimeter", " Formulae: area", etc. Each sub-category has multiple topics with between 6 and 10 question and answer pairs for the lessons, plus additional question answer pairs for the games and tests.

For each question/answer pair in a topic you get the question as picture, equation or text, the spoken question read by a robot, and an answer as both number or text and as audio. For most topics there are also 3 wrong answers prepared for each question.
