This lesson introduces algebra to give learners a basic understanding of simplifying algebra/ collecting 'like terms', substitution and forming expressions. Pictures are used to help learners grasp the idea of algebra. This lesson is designed to be interactive, with questions/ answers included. This also reduces the need for printing. This resource will prove useful in any math lesson. Learning aims are also included so students can measure their level of understanding and success in class. A lesson I have enjoyed teaching myself!
