My kids are in school in Vic - prep they get two readers a week, they get sight words and are tested weekly to see if they are ready for the next round. They have a mathletics log in to practice maths and have also been given other homework. This continues through year 1 and 2. In year 3 they don't get readers but have to read 10mins each night independently, read with an adult and have an adult read with them and discuss what they read. They do 10mins of mathletics a night and then get a homework task every fortnight. Once a week they do a big write that sometimes will come home to discuss then write at school.
