The main premise of a discovery lab is that students, through trials, will draw their own conclusions and make meaning of the math they’re exploring. Once they’re clear on these rules, they’re ready to move on to the challenges. Before moving on, be sure students understand that 1) they will always start at zero, 2) each arrow has a different length to represent a number, and 3) when a number is positive, the arrow points to the right when a number is negative, the arrow points to the left. 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.
