DecaCards are a classroom resource for teaching place value that is based on a familiar and powerful representation of ten: fingers. Designed to help students see ten as 10 ones or 1 ten, and to further develop understanding of two-, three-, and four-digit numbers. Tried and tested in classrooms across Australia and internationally.
