Max Maths, Year 2, Learn together, Missing numbers

In the Max Maths Year 2 curriculum, students are encouraged to learn together through interactive exercises that focus on finding missing numbers in addition sentences. On Workbook page 33, they encounter a series of exercises designed to bolster their understanding of basic addition and the concept of inverse operations. The exercises are presented in a story-like format, where characters Han and Padma take turns writing down addition sentences with one number covered up, and the other has to determine the missing number.

The section begins with an example where Han writes "35 + ___ = 40" and Padma figures out that the missing number is 5, because she knows that 35 plus 5 equals 40. Similarly, when Padma writes "___ + 25 = 30", Han deduces that the missing number is 5, as adding 25 to 5 results in 30. This interactive method of learning reinforces the students' ability to complete addition sentences by understanding the relationship between the numbers. Then, the workbook prompts students to apply what they've learned by writing down the missing numbers in a series of addition sentences, such as "15 + ___ = 20" and "36 + ___ = 40". The activity is designed to be engaging and educational, helping Year 2 students to strengthen their arithmetic skills in a fun and collaborative way.
