Max Maths, Year 3, Try it, Multiplying by teen numbers

In a Year 3 maths activity, students are encouraged to practice multiplying by teen numbers through a relatable scenario involving pencils in a box. The exercise begins with a 'Try It' section where the problem is to calculate the total number of pencils if there are 17 in one box and there are three boxes in total. To visualise the multiplication, counting blocks are used, depicting three groups of 17, which when added together, equal 51. The process is broken down further to show that 3 times 17 pencils can be seen as the sum of ones and tens, illustrating the concept of place value in multiplication. The final answer confirms that there are 51 pencils in 3 boxes.

Following the example, the 'Let's Practice' section invites students to apply their understanding to a series of multiplication problems involving teen numbers. They are presented with six different calculations, such as 12 times 4 and 32 times 3, challenging them to use their newly acquired skills to find the products. The activity is designed to help students become fluent in multiplying by teen numbers, an essential skill for their mathematical development. By completing these exercises, students reinforce their knowledge of multiplication and place value, building a solid foundation for more complex mathematical concepts.
