Multiplication and division - Use arrays - Presentation

The teaching slides on multiplication and division focus on the concept of using arrays to solve mathematical problems. Arrays are a visual representation that helps in understanding and performing multiplication and division calculations. The lesson encourages students to recall what an array is and to use physical gestures to demonstrate rows and columns. This visual approach is particularly useful in identifying the difference between, for example, 2 x 6 and 6 x 2, which are both represented on the image, yet arranged differently within the array.

Interactive activities are central to the lesson, prompting students to locate and describe arrays, such as finding 2 lots of 3 or representing the array with different objects. These exercises not only reinforce the concept of arrays but also encourage students to understand the commutative property of multiplication, as shown in number sentences like 2 x 3 and 3 x 2. Further activities challenge students to draw arrays that represent given multiplication sentences, such as 4 x 5 and 5 x 4, and to explore various ways to create arrays with a set number of cubes. The lesson concludes with independent work where students are tasked with creating different arrays and using them to complete number sentences, thereby solidifying their understanding of the relationship between multiplication, division, and arrays.
