Max Maths, Year 3, Learn together, Multiplying by 10 and doubling numbers mentally (2)

In a Year 3 mathematics lesson from Max Maths, students are learning to multiply by 10 and double numbers using mental strategies. The lesson involves a practical approach where children use counting blocks to understand the multiplication process. For example, to find the result of 14 multiplied by 10, students first consider what they already know: that 10 multiplied by 10 equals 100, and 4 multiplied by 10 equals 40. By combining these two pieces of information, they deduce that 14 times 10 is the sum of 100 and 40, which equals 140. This method breaks down the multiplication into more manageable parts, making it easier for students to comprehend and calculate.

The lesson further engages students by prompting them to discover a shortcut for multiplying any number by 10. This encourages independent thinking and helps them to recognise patterns in multiplication. By exploring these patterns, students can quickly and efficiently perform calculations without the need for physical counting aids. The aim is to develop their mental arithmetic skills, fostering a deeper understanding of the number system and multiplication concepts. This foundational knowledge is crucial for their progress in mathematics, equipping them with the tools to tackle more complex problems as they advance in their education.
