## Explanation of the toolThe ratio chart helps students think in ratios and is also a handy tool when doing math.Almost all methods use charts with two different quantities above and below, like price and weight, or number and price. The ratio chart is also used for part-total ratios. For example: a school has 140 students; 4 out of 5 students make use of daycare. In a number of methods the ratio chart is used to work with percentages. Example: how much is 18% of 1400? Students will first have the option to choose their own way of notating their calculations in relation to ratios. The importance of notating things systematically will be discussed. Working with the ratio chart will be explained based upon the experience level of the students. ## Tags |
