Addition and subtraction within 10 - Adding more - Presentation

In Lesson 12, young learners delve into the concept of addition through a series of engaging activities that encourage them to 'Add More'. The lesson prompts students to think creatively about number sentences, asking them to consider different ways of representing a given equation such as 3 + 4 = 7. The children are challenged to apply this understanding in various scenarios, including calculating the total number of vehicles like tractors and cars, as well as other items such as aeroplanes and pennies. The activities are designed to help students grasp the idea that adding to a number changes its value and to become comfortable with constructing and solving addition problems within 10.

As part of the lesson, students are also introduced to reasoning exercises that further solidify their understanding of addition. They are asked to determine the truth of a statement, such as whether adding one to a number keeps it the same, and to identify and correct mistakes in addition problems using visual aids like number tracks. Additionally, they explore the highest and lowest possible scores when adding numbers from a game involving marbles and buckets, explaining why certain totals cannot be achieved. The lesson concludes with independent work where students read questions carefully and express their answers as number sentences, encouraging autonomy in their mathematical reasoning.
