Rounding treasure hunt (10, 100, 1000, whole numbers, decimal places, significant figures)

A set of differentiated treasure hunts on rounding with 4 different difficulties. Skills covered include rounding to 10, 100, 1000 & whole numbers, rounding to decimal places, rounding to significant figures and a mixture of all rounding skills. Student record card and solutions included.

Difficulties include
★ Blue (easy) rounding to 10, 100, 1000 & whole numbers
★ Gold (medium) Round to a specified number of decimal places. (available FREE here)
★ Red (hard) rounding to a given number of significant figures
★ Purple (challenge) a mixture of all the rounding skills above

Students need to start on any random card and note down the letter on their recording card. They answer the question on that card then find another card that has the answer on (they then note down that letter and so on).

Suggestions for use:
★Print them off on A4 and scatter them around the room (students love getting out of their seats!)
★Print the cards off 4 to a page and give them to students individually to do on their desk
