Addition and subtraction - Subtract one from two-digit numbers 2 - Starter

In a Year 2 mathematics lesson, students are challenged with a series of addition and subtraction problems to enhance their numerical fluency. The lesson takes place during Autumn Term's Week 7, Day 5, and begins with a 'Fluent in Four' revision section. The pupils are tasked with solving problems that require them to add and subtract one and two-digit numbers. For example, they calculate the sum of 6 and 12, which equals 18, and they determine how many doughnuts do not have sprinkles by subtracting 3 from 9, resulting in 6 plain doughnuts.

The lesson continues with exercises that encourage students to use their understanding of number bonds and other strategies to solve subtraction problems efficiently. They are asked to subtract 9 from 46, which they can do by recalling their number bonds to 10, and similarly, they subtract 5 from 63. The use of a number line is also introduced as a tool to aid in solving calculations, such as finding the result of doubling 5 and adding 3. Additionally, pupils practice applying their arithmetic skills to real-life contexts, like adding up pence to find a total amount of money. Through these activities, students reinforce their mathematical understanding and develop problem-solving abilities.
