That’s the first step of the discovery lab. They’ll build the expression on the number line by starting at zero, placing the arrow that represents the first number, and then placing the second number. Students will be given positive and negative integers. The important part here is just to show them how to use the arrows and the number line itself. You can do this without getting into the math yet. I model a couple of examples and have the students follow along. We take a few minutes to just establish how to use the number line. I start the discovery lab with a workmat that has a number line on it (see the pic below). The best part is that they have to write rules, in their own words, to explain what is happening. The additive inverse discovery lab that I’ll walk you through here does a great job of giving students a concrete view of what is happening when they are adding and subtracting integers. I find that using number lines as much as possible is a great cornerstone for the building of the conceptual understanding when working with integers. It feels like you’re breaking down a wall and then rebuilding it. Getting past this strong built-in understanding can take a while. I’ve even found that many teachers have the same rigidity when it comes to adding and subtracting integers. That’s great! The flip side of that is that you have to work hard to break that schema so that they’ll understand negative integers. Students have a very strong background in positive integers. Through all of my experiences teaching about adding integers there is something that’s always true. Today I’ll share with you how my students get introduced to adding positive and negative integers through a discovery lab approach. Then, when you start the teaching and modeling, they have a place in their brain to put that new information. Discovery labs are an ideal way to start a new topic because it helps students build their own conceptual model right from the get-go. Why? Well, these activities help students face their misconceptions head on. One of my favorite ways to introduce new topics is with a discovery lab. We’re in love.Working with positive and negative integers is something that can throw students off at first. We have some wild nights with peanut butter. Say hello to the tall dark and handsome in my life. And this one has 29 grams of protein and only 135 calories. Get Fiasco Flair and Fiasco Family (coming soon to a screen near you) up and running!ĩ. Let’s try again with this making the bed thing because that seemed like a good idea.Ĩ. I used to be able to do the splits and it’s hilarious how much that is not the case now.ħ. (Because ahem a certain someone is moving to college and needs to fit their stuff in one suitcase so get ready for that.)Ħ. Remember how freaking fabulous it is and how much you love it. I should probably try to improve as a person this year. Smile, my love, because today is a beautiful day.Īw look at me I’m so cute and inspirational. I appreciate every single person around me (cough that means you cough).ġ0. And it’s nice to know that in trying times, the goodwill comes back for you. I like to think I did a decent job here, because I think being kind to other humans is so important. If any of you work in college admissions please please help me I’ll love and bake you cookies and cake forever and ever. ![]() Successfully navigate the college process. I think I did this for at least a month?Ĩ. Well since it’s very easy to develop recipes and take pictures and write and go to school and put the college in college try while trying to sleep sometimes maybe, I succeeded at this 1169423%. (Apparently sit up is two words? You learn something new every day.) I am the president of the no sit up left behind initiative. (I’ll work on this I promise because I love you more than I love cake and I love cake a lot). ![]() If they don’t involve cake then they were wrong. So please enjoy watching me cringe as I look over whatever resolutions I thought were a good idea last year. I am a strong independent woman and I don’t need no calendar to tell me when to change things. If there’s an improvement I want to make, I’ll make it. And my first decree as happiness queen was to not make any resolutions. My only resolution this year was to choose what makes me happy. I create single serving cakes to remedy the issue of my ensuing tight pants. I receive applause for such achievements. I make cakes at midnight and eat them all myself. ![]() I treat pajamas like workout clothes and workout clothes like acceptable wearing-in-public attire. LA had a few inches of rain in the past week, so basically half the city fled the country.īut apparently I’m now the kind of person who dances in the rain, which leads to laughing in the rain (mainly by other people), which leads to falling in the rain (mainly by me).
