### Grade Level: 1 ### Content Standard: - Operations and Algebraic Thinking ### Student-Friendly Objective: I can add to find the total number of balloons. ### Number Talk Problems (in the order that you plan to pose them to students): 1. Sammy has five colorful balloonsthree red and two blue. Later, his friend Mia brings over four more balloons, all yellow. How many balloons does Sammy have in total now? 2. If Sammy gives away two balloons, how many does he have left? 3. After getting one more balloon from a friend, how many balloons does Sammy have now? ### *Highlighted Problem for Strategy and Question Section Below*: **Sammy has five colorful balloonsthree red and two blue. Later, his friend Mia brings over four more balloons, all yellow. How many balloons does Sammy have in total now?** ### Anticipated Student Solution Strategy: 1. **Identify the Numbers**: Students will first recognize that Sammy has 5 balloons already (3 red and 2 blue). 2. **Adding New Balloons**: They will know that Mia brings 4 more balloons. The addition can be thought of as combining two groups: - Group one: 5 (Sammy's) - Group two: 4 (Mia's) 3. **Using Addition**: Encourage students to add the numbers together: \[ 5 + 4 = ? \] Students might use counters (like blocks or small toys) to physically represent the balloons, helping them visualize how to combine the groups. 4. **Counting to Find the Total**: Students can count all the balloons one by one or use
