Addition and subtraction - Subtract a three-digit number from a three-digit number exchange - Starter

In a Year 3 maths lesson, students are tasked with a series of calculations to test their proficiency in subtraction and addition, as well as their understanding of fractions. The lesson starts with a 'Fluent in Four' revision exercise that includes a subtraction problem where students must find the difference between two three-digit numbers, specifically 74 minus 28. Additionally, they are challenged to calculate the result of taking half of 84 and subtracting double the value of 12. These exercises are designed to reinforce their arithmetic skills and ensure they are comfortable with basic operations.

The lesson continues with practical word problems that relate to everyday scenarios, further strengthening the students' numerical abilities. For instance, they must figure out how many apples remain with a greengrocer who starts with 368 apples and gives away 134 of them to friends. In another problem, they calculate the combined total of football cards that Duncan and his sister possess, starting with Duncan's 24 cards and his sister's 53. Lastly, the students apply their knowledge of fractions to determine how much of a 250g bag of chocolates Tom ate when he consumed three-fifths of it. These exercises not only test their subtraction and addition skills but also their ability to work with fractions and apply mathematics to real-life contexts.
