Decimals - Halves and Quarters - Starter

Year 4 students are engaging in a series of mathematical exercises designed to strengthen their fluency in working with decimals, specifically focusing on halves and quarters. The set of activities, titled "Fluent in Four - Revision," includes a variety of tasks such as calculating time in the format of '19 past 7 p.m.', performing division with simple numbers like '63 ÷ 9', and handling more complex divisions such as '312 ones divided by double 4'. Students are also asked to complete number lines with decimal sequences ranging from 9.1 to 9.9 and 28.1 to 28.9, ensuring they understand the incremental progression of tenths.

Practical geometry is incorporated into the lesson with an exercise asking students to determine the perimeter of a rectilinear shape, where each square on the grid measures 1cm by 1cm, reinforcing measurement and calculation skills. Division problems such as '18 ÷ 10' and '30 ÷ 10' are presented to help students grasp the concept of dividing by ten, translating whole numbers into decimals. Additionally, real-life applications are included, such as a scenario where Mark has 9 meters of rope and uses 187 cm to make a skipping rope, prompting students to perform subtraction in different units and complete part-whole models to further develop their understanding of fractions and division.
