They will learn that an acute angle is less than 90 degrees, 90 degrees is a right angle and an obtuse angle is more than 90 degrees but less than 180 degrees. There is a teaching presentation accompanied by differentiated activities with a range of fluency, reasoning and problem-solving questions.
