Divide numbers mentally using known facts and place value

ArithmeKit 5.19 is a comprehensive set of exercises designed to help students in Year 5 enhance their mental arithmetic skills, particularly in division, by utilising known facts and understanding place value. A variety of division problems are presented, requiring students to divide large numbers, sometimes by decimals, to find the quotient. For example, dividing 560,000 by 80 results in 7,000, and dividing 560 by 0.08 yields the same quotient. The exercises encourage the use of mental methods, either by performing calculations 'in your head' or with simple jottings, to solve the problems efficiently.

Another aspect of the ArithmeKit focuses on creating and identifying patterns with numbers. Students are tasked with using the multiplication fact 6 x 7 = 42 to represent the number 0.6 in seven different ways, prompting them to notice patterns in place value and number relationships. The kit also includes matching pairs activities where students must find two calculations that result in the same answer, such as 560,000 ÷ 80 and 8, enhancing their understanding of how numbers can be manipulated using division. Additionally, the resource provides opportunities for students to create their own problems, further developing their numerical fluency and problem-solving skills.
