Addition and Subtraction - Subtracting whole numbers with more than 4-digits - Starter

In an engaging starter activity for Year 5 students during the Autumn term, the focus is on developing fluency in subtracting whole numbers with more than four digits. The exercise begins with a 'Fluent in Four' revision task where students are challenged to add together two multi-digit numbers, sharpening their mental arithmetic skills. Following this, the children are asked to complete a part-whole model and corresponding sentences that combine ones, hundreds, and tens, further reinforcing their understanding of place value and addition.

The lesson continues with a subtraction task where students are instructed to use the formal written method to subtract a four-digit number from another. This methodical approach helps them to grasp the concept of borrowing and regrouping as they work through the calculation. Additionally, learners are encouraged to explore the concept of '1,000 more' and '1,000 less' than a given number, which aids in their comprehension of the number system and scale. To round off the starter, students complete a table involving quarters, converting them into wholes and remaining quarters, thereby integrating their knowledge of fractions with their arithmetic skills. This multifaceted approach ensures that the students are well-prepared for more complex mathematical challenges.
