Double numbers

The ArithmeKit 219 from Buzzard Publishing offers an engaging and educational activity focused on the concept of doubling numbers. It presents a variety of exercises to help students understand and practice this mathematical principle. For instance, the kit includes a matching pairs game where students must find two numbers that, when doubled, result in the same product. They are also encouraged to create their own matching pairs problems involving doubles, further reinforcing the concept. The task is designed to help students recognise patterns and relationships between numbers, such as double 6 matching with 12, and double 15 with 30.

In addition to matching pairs, the ArithmeKit challenges students to use practical resources to visualise and confirm the results of doubling numbers. For example, they are tasked to convince themselves that double 25 is indeed 50, and to persuade a character named Coco that double 17 equals 34. The kit also includes a problem-solving element where students must place digits into blank spaces to complete equations correctly, such as finding the missing number that when doubled equals a given number. This encourages students to think critically and apply their knowledge of doubling in different contexts. The exercises also delve into the properties of numbers, prompting discussions on whether doubling an odd number can result in an odd or even outcome. The comprehensive approach of the ArithmeKit ensures a deep understanding of the concept of doubling for students at various levels of mathematical proficiency.
