Decimals - Activity: Tenths and Hundredths Activity - Starter

The mathematics activity for Year 4 students during Spring Term Week 9 focuses on decimals, specifically tenths and hundredths. The starter activity involves a practical problem where students must calculate the weight of chocolate eaten by two individuals, Zach and Rosie, from a 300g chocolate bar. Zach consumes 6/10 of the bar, while Rosie eats 4/10. Students are tasked with determining how many more grams Zach eats than Rosie. This real-world application helps them understand the concept of tenths in a tangible way. Additionally, students are asked to locate and order numbers on a number line, reinforcing their understanding of numerical sequences and place value.

Another part of the activity requires students to solve a measurement problem. They must find the combined length of two wooden boards, one measuring 28 cm and 25 mm, and the other 37 cm and 16 mm. This exercise not only tests their ability to add lengths in centimetres and millimetres but also their understanding of converting between these units. Alongside these tasks, the students practice addition with multi-digit numbers, further enhancing their arithmetic skills. The activities are designed to be engaging and challenging, promoting a deeper comprehension of decimals and their practical applications in everyday contexts.
