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

In the Year 3 mathematics lesson for Autumn Term's fifth week, students are introduced to subtracting one-digit from two-digit numbers. The lesson begins with a 'Fluent in Four' revision exercise, designed to test their quick arithmetic skills. Students are asked to use a number line to solve calculations such as adding three ones and one ten to forty-five, resulting in fifty-eight, and combining forty-three with twenty-four, which totals sixty-seven. They also practice their addition skills with a slightly more complex sum: nine plus two hundred and thirty-four equals two hundred and forty-three.

Further exercises aim to solidify the students' understanding of place value, as they identify numbers represented in the tens and ones format. For instance, the digits 8 and 2 represent the numeral eighty-two, and similarly, 9 and 2 represent ninety-two. The lesson also includes a matching activity where students connect turns, such as a quarter turn clockwise or a half turn anticlockwise, to their corresponding descriptions, enhancing their spatial awareness and understanding of angles. This engaging and varied approach helps ensure that students are not only fluent in their calculations but also have a strong grasp of fundamental mathematical concepts.
