Decimals - Hundredths on a Place value Grid - Starter

In an engaging mathematics lesson tailored for Year 4 students during their Spring Term, the focus is on understanding hundredths using a place value grid. The session commences with a 'Fluent in Four' revision exercise, where pupils tackle a series of arithmetic problems involving fractions and operations such as addition, subtraction, and comparison. This warm-up is designed to consolidate their arithmetic skills and set the stage for the day's learning objective. Students are then presented with a table to complete, which requires them to convert fractions into decimals, specifically dealing with hundredths. For instance, they learn that 20 hundredths is equivalent to the decimal 0.20 and that 47 hundredths is represented as 0.47.

The practical application of decimals is further explored through real-life problems. One such problem asks students to calculate the total amount of money in a jar, requiring them to express the answer in pounds and pence. Another problem sets up a comparative scenario where Malachi has two bottles of water, each containing 1 litre and 200 millilitres, while Zach has seven cans of sparkling water, with 350 millilitres in each can. The challenge for the students is to determine who has more water. Through calculation, they find that Malachi's total of 2,400 millilitres is slightly less than Zach's 2,450 millilitres, thus concluding that Zach has the most water. These exercises not only test the students' ability to work with decimals and fractions but also help them apply mathematical reasoning to everyday situations.
