Halve decimal and whole numbers

The ArithmeKit 5.21 from Buzzard Publishing, part of the CanDoMaths series, is an engaging resource designed to help Year 5 students develop their skills in halving both decimal and whole numbers. The exercises prompt students to notice patterns when numbers are halved and to match them to their correct halves. For example, numbers like 5.65, 5.15, and 5.55 are presented for students to observe the halving process. The activity continues with a range of numbers, including those in the double digits like 11.3 and 11.9, where students must apply their understanding to find the correct halves. Additionally, the resource includes a set of numbers such as 3.4, 8.4, and 12.4, which students must halve, reinforcing their arithmetic skills and ability to work with decimals.

The kit further challenges students with problems that require halving numbers such as 16.8, 45.2, and 98.4, ensuring they practice and consolidate their understanding of halving large numbers and decimals. It also encourages critical thinking through problems where students must use digits 0-9 to complete mathematical statements, and even create their own matching pairs problems. The resource includes an intriguing discussion point where students must use practical resources to prove why Coco's method of halving 11.7 to get 5.535 is incorrect, and determine whether Colin's method of halving 15.3 to get 7.8 is correct. This not only teaches them the correct halving technique but also fosters a deeper comprehension of the mathematical concepts involved.
