Activity ages 9-14 years Ancient civilisations in the past used different systems of numeration. These number systems had different ways to arrange symbols to form numerals. Some used additive or subtractive notation whilst others used multiplicative or positional notation. In this activity (which is part of the place value unit) students will explore ancient Roman numeration and compare this with the Hindu-Arabic numeration system that we use today. The activity card includes instructions and follow up activities.
