Addition and subtraction - Pattern spotting - Starter

In this engaging maths activity for Year 3 students, the focus is on mastering addition and subtraction with an emphasis on pattern spotting and revising calculations involving hundreds. The task begins with a simple subtraction problem: 73 minus 54, and then challenges students to subtract half of 60 from 94. These exercises are designed to reinforce the students' ability to perform basic arithmetic operations and understand the concept of halving numbers. The activity continues with a number track sequence, where children must identify the smallest and greatest numbers, and then continue the sequence by adding or subtracting 100 to or from given numbers, such as 428 minus 400 and 73 plus 100.

Further, the worksheet prompts students to fill in the blanks to complete sentences involving the concept of a whole and its quarters, providing a practical application of fractions. For instance, they must determine what a quarter of a given number is and apply this knowledge to a real-life scenario: Leanna has 24 marbles and gives a quarter of them to her sister. The children are tasked with calculating how many marbles each person will have after the division. This exercise not only tests their mathematical skills but also their comprehension and ability to apply mathematical concepts in everyday situations. The worksheet concludes with sentence completion exercises that consolidate their learning and ensure they understand the relationship between wholes and parts, particularly in the context of sharing and division.
