The video tutorial begins with Romo introducing a seashell counting activity to prepare a necklace for a sea turtle. The activity involves finding and counting seashells, using basic addition. The next section introduces a 'Guess the Number' worksheet, where students learn to use equations to find missing numbers, applying the associative property. The final section covers a 'Part-Part-Whole' worksheet, teaching students to find missing parts using subtraction and addition strategies. The video concludes with a summary of the strategies used.
