Two brand new sets of pages for Year 5 which look at angles on a straight line. Both are very different; the first looks at calculating the angles on a straight line using the knowledge that the sum of the angles comes to 180 degrees. The second looks at measuring angles on a straight line using a protractor. Of course, it is well worth reminding children that the angles they measure should add up to 180 degrees, which is an excellent way to check that the measurement has been carried out correctly.
