Operations on Integers and Decimals

Complete lesson originally aimed at year 10 students.

This is planned / designed as a round robin exercise of 10 minute periods.

There is a timer on the instruction page, after which are the task sheets and their answers.
Original aim is to have the answer sheets at the back of the room, when a student finishes the task on the table they move to check their answers. If all students finish and mark early the timer is reset (back arrow) and the students move tables. (likewise if more time needed).
Tasks do vary with one being collaborative and two investigative (that may need extra time), all are non-calculator where the icon shows.
