## More information

The zip file contains a worksheet activity, and a spreadsheet activity, and solutions.

In the worksheet activity, students have to find remainders to work out what Chinese Zodiac (animal and element) particular years have. Students then need to make predictions about how often the Chinese Zodiacs will repeat themselves, which links to lowest common multiples.

The spreadsheet activity follows the worksheet. Here students write formulae to automate the process of finding the animal/element for each year and check their predictions.

The maths of remainders/modular arithmetic and the spreadsheet skills required are similar to those needed in our last resources ‘New Year Calendar Resources’, so you could link these tasks.
