Max Maths, Year 4, Work Book, Multiplying 2-digit numbers with regrouping

In the Max Maths Workbook for Year 4, one of the practice exercises focuses on multiplying 2-digit numbers with regrouping. The first problem presents a practical scenario where students must calculate the total number of cherries in three containers, given that one container holds 28 cherries. The exercise encourages the use of counting blocks to visualise the multiplication process, grouping tens and ones to arrive at the final answer. This method not only helps in understanding the concept of multiplication but also in reinforcing the skill of regrouping when dealing with larger numbers.

The workbook continues with similar multiplication problems, such as determining the total number of eggs in four baskets when each basket contains 24 eggs. Again, counting blocks are used to group tens and ones, aiding students in visualising the multiplication and regrouping process. Additionally, the workbook provides a series of multiplication problems to be solved using the column method. These range from simpler multiplications like 16 times 4, to more complex calculations such as 97 times 8. This variety of exercises helps students practice and master the skill of multiplying 2-digit numbers with regrouping, an essential mathematical technique at this stage of learning.
