Mastering Number Symbols up to 200 and Grouping Strategies

Section role: supports the 'Naming Our Numbers and Master Groups' section while the teacher formalizes the grouping strategies discovered by students and introduces symbols up to 200. Slides: (1) Title — 'Mastering Groups and Numbers to 200'; (2) From Piles to Groups — visual breakdown showing 10 groups of 10 making 100; (3) Reading Numbers Up to 200 — symbols like 142, 165, and 189 displayed clearly; (4) Tricky Number Names — spelling guides for 'forty', 'fifty', and 'eighty'; (5) Before, After, and Between — examples using 156 and the range between 150 and 152; (6) Let's Practice Together — reading sequences aloud, building on the baseline counting to 100 from earlier activities. Closing slide: 'What number comes right after 199, and how do we write its symbol?' — hands control back to the teacher to transition into the abstract counting and worksheet tasks in the next section.
