Investigating currency rates around the world is an effective way to practise multiplying and dividing decimal numbers by 10, 100 and 1000. Use this activity, What’s today’s rate? as a Mental Warm-up with your Stage 3 students at least once a week. Your students will become proficient at collecting online data and multiplying and dividing decimals in their head.
They challenge a partner to answer random questions related to the data they collect. They will see how each week our currency is worth more or less or may even stay at the same exchange rate. The decimal differences will make sense rather than just being a number on a screen or a page in a workbook.
