Addition and subtraction - Add a two-digit and ​three-digit number crossing 10 or 100​ - Starter

In this engaging maths session for Year 3 students, set during the Autumn Term's seventh week on the second day, children tackle the fundamental concepts of addition and subtraction with a focus on crossing tens and hundreds. The starter activity, known as 'Fluent in Four - Revision', prompts students to warm up their numerical skills by calculating the difference between two numbers, such as 93 and 61. They are also challenged to double a number and then subtract another, specifically doubling 32 and subtracting 27, honing their mental arithmetic abilities.

The lesson continues with a variety of exercises designed to strengthen the pupils' understanding of mathematical operations. Students are asked to determine the fraction represented by a circled portion of an object, further enhancing their grasp of fractions. A real-life scenario is presented where Tom receives money from his parents, and students must calculate his total savings, reinforcing their skills in practical addition. Additionally, they face a problem that involves the addition of a two-digit number, 74, to a three-digit number, 423, and must find the sum. These activities not only bolster the children's computational skills but also encourage them to apply their knowledge to solve problems effectively.
