Addition, Subtraction, Multiplication and Division - Multiply 3 digits by 2-digits (arithmetic) - Presentation

In a comprehensive set of teaching slides designed for enhancing mathematical fluency and reasoning, students are introduced to the concept of multiplying three-digit numbers by two-digit numbers. The presentation begins with a discussion prompt, encouraging students to consider the similarities between multiplying two-digit numbers and extending this to a three-digit by two-digit scenario. The slides then guide students through a series of structured activities, starting with an example where they multiply 132 by 14. This exercise not only reinforces the multiplication process but also highlights the importance of the digit zero in place value and calculations.

Further activities include a variety of multiplication challenges, such as calculating the product of 642 and 34, and more complex real-world problems like determining the area of a park measuring 134 by 68 yards. These exercises are designed to strengthen students' understanding of multiplication and its applications. Additionally, reasoning tasks challenge students to identify and correct mistakes in given calculations, such as spotting errors in Zach's maths work, where he has omitted necessary steps or exchanges. Through these tasks, students develop critical thinking and problem-solving skills, which are crucial for mastering more advanced mathematical concepts.
