Addition, Subtraction, Multiplication and Division - Formal multiplication 2-digits by 2-digits - Planning

The Year 6 mathematics lesson plan focuses on the formal method of multiplying two 2-digit numbers. The class begins with a recap of the area model used in previous lessons, setting the stage for students to transition to a more formal written approach. The first activity involves a step-by-step explanation of the column method, using 26 multiplied by 13 as an example. The children learn to partition the multiplier and multiply the individual digits, placing the results in the correct value columns. The significance of the zero as a placeholder is highlighted, particularly when multiplying by 10, to ensure accurate placement of digits. After the demonstration, students practice this method with various calculations, sharing their answers and rectifying any misunderstandings.

Subsequent activities require students to complete missing parts of calculations and apply the learned method to new problems, with annotated examples provided for support. Group work and independent tasks aim to deepen their understanding and fluency in this multiplication technique. The lesson also prompts critical thinking through key questions about the importance of zeroes, the multiplication process, and exchanges in the column method. Misconceptions are addressed, ensuring students grasp the connection between the area model and the formal written method. The plenary includes a reflective 'Give me five' exercise, where students consider what they've learned, the skills they've used, and what they found challenging. Differentiated worksheets cater to varying levels of proficiency, from working towards fluency to achieving greater depth, with problem-solving tasks like investigating if certain products can be achieved by multiplying two 2-digit numbers.
