Class/ Group Activity. DifferentiatedA series of easy, medium and difficult expressions for pupils to substitute values into. Instructions: Each column contains 5 cards to be ordered. Assign a value to x and order the cards. Negative numbers can be used to increase the difficulty of the exercise.

To substitute positive and negative integers into formulae. A lesson and a game that involves codes to test students' knowledge of algebraic expressions, substitution and negative numbers

Algebra Level 5 Group activity A game where students must roll a dice and then use the score plus the instructions on the square they are on to decide how many spaces they can move. This then links into forming algebraic expressions

Algebra Level 6 Algebra Level 7 Expanding brackets Whole class activity Randomly generates all different types of brackets for students to expand and simplify. also gives answers
