This highly visual PowerPoint revises what decimals are and teaches students how to multiply and divide decimals. It includes a link to an online game and also includes lots of interactive practice questions.
It starts by asking teachers to have a "washing line" set up- a string tied between 2 chairs with a set of pegs and basic decimals (e.g. 0.1, 0.2... 1.2, 1.3, etc) made by the teacher. The "washing line" activities are incorporated throughout the Ppt.
