Addition and subtraction - Compare number sentences - Starter

In a Year 2 mathematics lesson, students are presented with a series of exercises designed to consolidate their understanding of addition and subtraction. The "Fluent in Four" revision activity is a part of the Autumn Term curriculum for Week 5, Day 3. It starts with a problem-solving task where students must determine the missing number in a multiplication sentence, exemplified by "6 × _ = 60", encouraging them to identify patterns and use inverse operations to find the answer. Another challenge involves comparing a multiplication sentence with an equivalent value, such as "_ = 9 × 5", which tests their ability to recognise and calculate equivalent expressions.

The lesson progresses with a set of calculations for the students to complete, such as "16 + 3 = 19". They are then asked to consider which related calculations can be used to verify their answers, promoting the concept of inverse operations as a means of checking work. For example, "19 – 3" and "19 – 16" could be used to check the addition of "16 + 3". Students are encouraged to complete the given sentences by filling in the blanks with the correct numbers, reinforcing their arithmetical skills. The task also includes a practical application question, asking "How many rectangles?" to connect their numerical understanding with geometric contexts. This multifaceted approach to learning addition and subtraction ensures a thorough grasp of the concepts and their applications.
