Repeated Addition: Visual Models and Arrays

Section role: supports the building of the repeated addition model in Section 3 while the teacher uses the students' board work from the toy store challenge to bridge to theory. Slides: (1) Title — 'Building the Repeated Addition Model'; (2) Equal Groups — bullets: definition of equal groups, visual example of 3 boxes with 5 donuts each; (3) From Counters to Math — bullets: bridging the toy car activity (6 + 6 + 6 + 6) to the concept of repeated addition; (4) Visual Arrays — image of a carton of 12 eggs as 2 rows of 6, prompt: 'What is the addition sentence for this?'; (5) Common Mistakes — bullets: addressing why 4 groups of 6 is written as 6 + 6 + 6 + 6 and not 4 + 6, emphasizing the role of the addend; (6) Vocabulary Recap — terms: equal groups, repeated addition, sum. Closing slide: 'How does adding the same number help us find the total faster?' — sets up the individual pattern master check section that follows.
