First Grade Talking Points

• "Today, we are going to learn about addition, which is combining numbers together."
• "We will start by adding numbers up to 10. Can you think of any examples where we add small numbers together in real life?"
• "Counting on is a strategy we can use to add numbers. It means starting with one number and counting up from there."
• "Rolling dice can be a fun way to practice addition. We can use the program maths online to simulate dice rolling."
• "Now, let's move on to adding numbers up to 20. Can you think of any examples where we add larger numbers together in real life?"
• "Remember, counting on can help us add larger numbers too. We start with one number and count up from there."
• "Using a number line can be helpful when adding numbers. It helps us see the sequence of numbers and add them together."
• "Sometimes, we encounter addition problems with a missing number. We need to figure out what that missing number is by adding the other numbers together."
• "Lastly, we will learn how to add three numbers together. This can be a bit more challenging, but with practice, we can become experts!"
