Addition and subtraction - Subtract with two-digit numbers not crossing 10 - Starter

In a Year 2 mathematics session focused on subtraction with two-digit numbers, not crossing the ten boundary, students are presented with various problems to solve. The session begins with a 'Fluent in Four' revision exercise, where pupils are encouraged to calculate answers to multiplication questions such as '6 × 5', reinforcing their times tables knowledge. They then move on to a practical application of addition; for instance, Tia, a pen collector, receives 14 pens on Monday and buys another 28 on Tuesday. Students are tasked with calculating the total number of pens Tia has, which is a straightforward addition problem resulting in 42 pens.

Beyond simple arithmetic, the lesson also includes exercises to complete sentences with missing numbers, promoting understanding of number relationships and operations. For example, students might be asked to figure out the number of cherries in each column and the total number of columns to calculate the total number of cherries by performing addition. Furthermore, they are challenged to identify and write down or circle all the rectangles presented to them, which integrates shape recognition with numerical operations. These varied activities are designed to enhance the children's fluency in basic arithmetic while also introducing them to more complex mathematical concepts.
