Subject: Fractions
To teach fractions begin with what are fractions relative to whole numbers. Whole numbers are for counting. Whole numbers answer the question How many? For example, cars, horses, trees, houses. There are no half a house or half a car or half a horse. Fractions on the other hand are used to answer questions on measures: how far, how heavy, volume, weight kilos. To give accurate measures we need fractions. One half of a distance, half a year, a fraction of a weight or time. Next draw a rectangle, a circle or square. Emphasize that a whole is 1 and fractions and decimal fractions have been invented to measure accurately units less than 1.Divide the figure into 2 equal parts and write 1/2 in half the figure and 1/2 also in the other half. Then write outside the figures 1/2 + 1/2 = 2/2 = 1. This is the beginning , should be the beginning of teaching fractions. Yours in Math, laurodelara@Skyinet.net
