Divide by 10, 100 and 1000

The ArithmeKit 5.17 from CanDoMaths presents a series of exercises designed to help students understand the process of dividing numbers by 10, 100, and 1000. Students are tasked with finding matching pairs in a set of division problems, identifying what's missing in given equations, and creating their own problems that involve these divisions. For example, dividing 879 by 100 results in 87.09, and dividing 8079 by 1000 yields 8.79. Through these activities, students will notice patterns, such as how the decimal point moves to the left by one, two, or three places depending on whether they're dividing by 10, 100, or 1000, respectively. They are encouraged to write their own questions that lead to the same answer, further reinforcing their understanding of the concept.

Additional exercises prompt students to calculate divisions, such as 8900 divided by 10 equals 890, and 89,000 divided by 100 also equals 890, illustrating the consistent relationship between the divisor and the movement of the decimal point. The material includes a variety of problems that range from simple to more complex, with numbers increasing in size, to challenge students at different levels. For instance, dividing 6709 by 100 results in 67.09, while dividing 4560 by 1000 gives 4.56. The exercises are designed to build confidence in manipulating numbers and to deepen the students' understanding of place value and the impact of division on the position of digits within a number.
