Practise measurement, scale and navigation at your own pace. Choose a difficulty, try each question on paper or in your jotter, use hints only when you need a start, then show answers to check your work.
Build your confidence
Choose a difficulty and practice length, write down your working, then reveal answers only when you are ready to check. Hints give a starting point without giving away the answer.
