Third Grade Talking Points

• "Ribs are bones in our body that protect important organs like the heart and lungs."
• "They are located in our chest and form a cage-like structure."
• "Ribs are long and curved, and they connect to the spine at the back."
• "We have 12 pairs of ribs in our body, making a total of 24 ribs."
• "The top 7 pairs of ribs are called 'true ribs' because they are directly connected to the breastbone."
• "The next 3 pairs of ribs are called 'false ribs' because they are indirectly connected to the breastbone."
• "The last 2 pairs of ribs are called 'floating ribs' because they are not connected to the breastbone at all."
