Hi, I'm Rachel, and today we're going to be going over how to teach second graders addition and subtraction using number lines. Number lines are a fabulous way to have the kids start to visualize what they are doing instead of just doing it by you know, routine and memory, they can actually see. They're not just going to memorize that seven minus four is three, they're actually going to be able to understand it. So usually in second grade they haven't learned negative numbers yet so we'll just start off at 0 and you know, you can write a whole number line from there. I'll just go up to seven for now. So then you can have them, you know, do certain addition and subtraction problems using the number line and actually counting it out so they can visualize what they are doing. So that if they have two plus four, they can start at the two and add four, one, two, three, four to get six. So they don't just memorize but they actually understand. Same with if they have you know, seven minus three, they can start off at the seven and subtract three to get four. This is just a great way for them to practice of course, you know you can do it much more than seven, you can go up to 100, you can go further than that and just having them add and subtract instead of just two numbers, you can have them do three or four and this way they can visualize what they are doing and start to understand and comprehend it more. I'm Rachel and thanks for learning with us today.
