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. Devour.Working with positive and negative integers is something that can throw students off at first. Scrape the batter into the prepared loaf pan and bake in the oven at 350☏ for 27-32 minutes, or until a toothpick inserted in the center comes out clean. Add in the eggs or egg replacer, mashed banana, vanilla extract, molasses, and almond milk and stir until all the ingredients are incorporated and the batter is uniform. In a large bowl, stir together the flour, sugar or erythritol, baking powder, baking soda, salt, and cinnamon.Generously grease or nonstick spray an 8x4 loaf pan and set aside. 3 eggs OR 1 ½ Tablespoons of Ener-g egg replacer stirred with 6 Tablespoons of water until thick.1 ¾ cup white whole wheat flour OR almond meal.That being said, the almond meal version is not as sturdy.īehold! Oh that texture. They are both excellent, but the almond lend an extra special buttery texture. Just keep in the back of your mind that the batter is also relatively thick, which contributes to the sturdiness.īelieve it or not, the response was unanimous that the version with almond meal (gluten free, grain free) is actually better than its wheat flour counterpart. The final product is very moist, sturdy, and perfectly sweet with a lovely, delicately spiced flavor. I reserve being in love with bread for very special bread occasions, and this hunk a’ burning love certainly qualifies. I am a life long lover of banana bread, and it is safe to say I am in love with this healthy banana bread recipe. Let’s just say that the big fork came out again. Delighted, I made a few more adjustments, baked it up in a loaf pan, and crossed my fingers. My taste testing squadron (hi Mom!) loved my little biscotti detour. This tastes a lot like banana bread! I’m going to have to keep eating to verify… yup. Throw up your oven mitt clad hands and take the pan out of the oven. Take notes.) Cook way longer than directed. That’s okay! Nothing is going to happen as it should! (This is deep life stuff. Okay, it’s not going to harden as it should when it cooks. I’m sure it’s not that important! I’ll use something else instead. Make many many changes to said worthwhile jumping off point, but make sure to justify all of them. I got an A in geometry last year, so I’m an expert on logic. I mean, I wouldn’t know, but that sounds logical. Even though your final product will be completely unrecognizable, you want your original jumping off point to be worthwhile. Make sure you start of with a good recipe. You’re impressed, no? You want to know how to replicate such a feat, yes? Honesty time? This healthy banana bread was supposed to be healthy vanilla biscotti.
