Multiplication and Division (1) - Multiply by 10 - Presentation

In the lesson focused on multiplication by 10, students are invited to revisit their knowledge of multiplying whole numbers by ten. The lesson begins with a reflection on the 10 times table and an exploration of the commutative property of multiplication. The students are then engaged in a series of interactive activities. The first activity involves completing sentences to demonstrate the process of multiplying by 10, using visual aids such as place value grids to reinforce understanding. For example, when presented with a series of ones arranged in rows on a grid, students must determine the total value by multiplying the number of ones in each row by the number of rows, thus solidifying their grasp of the concept.

Further activities build on this foundational skill, with students using place value counters to work out multiplications such as 8 x 10 and 10 x 7, translating these into written calculations. The lesson challenges students to apply their knowledge to real-world scenarios, such as determining the number of passengers on a number of buses or the total pencils in pots, using bar models to visualize the problem. Additionally, reasoning exercises are included to deepen understanding, such as determining the original number when a product falls within a specific range. Independent work tasks encourage students to represent calculations, draw bar models, and match statements to the correct visual representation, ensuring a comprehensive understanding of multiplying by 10.
