Breaking numbers in multiplication helps simplify calculations and make them more manageable. It allows students to work with smaller parts of a number, making it easier to understand and solve multiplication problems.
The area model is used in this lesson because it provides a visual representation of how breaking numbers can simplify multiplication. It helps students see the relationship between different parts of a number and how they contribute to the final product.
Breaking numbers into groups of ten helps in multiplication by making calculations easier. It allows students to work with multiples of ten, which are often easier to multiply or divide mentally. By breaking larger numbers into groups of ten, students can simplify the multiplication process and develop a stronger number sense.
