Introducing Multiplying 2-Digits by 1-Digit - PowerPoint

This educational resource is designed to help Year 3 students grasp the concept of multiplying a 2-digit number by a 1-digit number. The objective is to introduce students to this fundamental mathematical operation through a series of interactive PowerPoint slides. The presentation guides students through the process of completing various multiplication calculations. For example, students are shown how to add the number 21 four times (21 + 21 + 21 + 21) and then to recognise that this is the same as multiplying 21 by 4, with both methods resulting in the answer 84. This visual and repetitive approach helps to reinforce the concept of multiplication as repeated addition.

Further slides offer additional practice, where students are encouraged to match repeated addition expressions to their equivalent multiplication sentences. For instance, they'll see that 15 added to itself four times (15 + 15 + 15 + 15) corresponds to the multiplication of 15 by 4. Place value counters are used as visual aids to assist in the comprehension of calculations, such as 44 added to itself equalling 88, which is the same as 44 multiplied by 2. The resource also includes worksheets that prompt students to identify and correct mistakes in multiplication calculations, such as recognising that multiplying 3 by 3 is different from multiplying 30 by 3, ensuring a deeper understanding of the multiplication process and the importance of place value.
