Multiplication and Division - Divide 3-digits by 1-digit - Presentation

In a comprehensive set of teaching slides focused on multiplication and division, students are guided through the process of dividing three-digit numbers by one-digit numbers. The lesson provides a structured approach, starting with an exploration of how methods adapt when transitioning from dividing smaller numbers to larger ones. Students are encouraged to discuss and compare calculations such as 34 ÷ 4 and 253 ÷ 3 to understand the concept better. The lesson continues with practical activities where students use place value counters to break down numbers into hundreds, tens, and ones (H, T, O) before performing division. For example, 609 ÷ 3 is divided into 600 ÷ 3, 0 ÷ 3, and 9 ÷ 3, with the results combined to give a final answer.

Further activities include dividing numbers like 884 by 4 and 8, and 489 by 2, using the same method to reinforce understanding. Students also explore flexible partitioning as a strategy for division, where they distribute a three-digit number across place values before dividing each part. This method is exemplified with calculations such as 981 ÷ 4, which is partitioned into 800 ÷ 4, 160 ÷ 4, and 21 ÷ 4, resulting in a quotient with a remainder. The lesson then challenges students with reasoning tasks, such as completing part-whole models for 208 ÷ 8 and creating three-digit numbers divisible by various factors using a set number of counters. The session concludes with independent work where students apply these methods to solve division calculations and consider different partitioning strategies to divide efficiently.
