Accurately calculate a series of integers (1, 2, 3, 4, 5) using mental addition and subtraction strategies.
This Sludge Eliminator card contains 24 Mental Addition and Subtraction operations, with a twist ...and a turn.
These calculations take place within an innovative machine known as the Sludge Eliminator, which chemically changes useless, smelly, toxic sludge into a vibrant selection of weatherproof glossy paint… well let’s just pretend it does anyway.
This fun and creative approach inspires the students to
persevere through numerous mathematical operations within an imaginative environment.
To cater for a wide range of ability, four different starting numbers can be chosen; a 1 digit, 2 digit, 3 digit & a 4 digit number.
Furthermore, mental operations may involve calculating a simple series of 3 different integers to create RED paint, through to a complex series of 34 integers...as the ‘sludge’ travels through the ‘eliminator’ chutes and transforms into WHITE paint.
