Multiplication and Division - Multiply 2-digits by 1 digit - Starter

The 'Fluent in Four' revision activity is designed to enhance the mathematical fluency of Year 4 students, focusing on the practical application of subtraction, multiplication, and understanding of fractions. In the first task, students tackle subtraction problems, such as finding the difference between 5,391 and 486, and then subtracting complex numbers like '32 thousands, four tens and five ones' from 'seventy-nine tens and 6 ones'. In multiplication, they calculate the product of 43 and 3, reinforcing their skills in multiplying 2-digit numbers by 1-digit numbers.

Another engaging part of the lesson involves Zach and Malachi sharing a pizza. Students are asked to determine what fraction of the pizza remains after Zach eats 1/9 and Malachi eats 1/3 of it. This exercise helps students grasp the concept of adding and subtracting fractions with different denominators. Additionally, the activity includes place value problems where students must complete calculations by adding or subtracting from the number 554 to reach specified totals. By comparing the calculations, students identify similarities and differences, enhancing their understanding of number properties and operations. The use of place value counters in these exercises aids in visualising and solving the problems, providing a hands-on learning experience.
