Now that I'm a math coach, I've been helping teachers learn how to integrate Algebra Tiles into their lessons. Alternately, if our tiles were blue, we would need to pair them up with a red tile. This post and accompanying Desmos Activity Builder is a result of a… To use algebra tiles to model an equation, we place the relevant number of variable rectangle tiles and number square tiles for the left side of the equation and for the right side of the equation. Create an equation with a variable on both sides. If our numbers are negative, then our square tiles can be a different color to show the difference. Let's take a look at how we can use algebra tiles to help us model and solve an equation. For example, if the expression is 3x– 2, place 3 green x tiles and 2 red 1 tiles in one half of the workspace. Because we just doubled our x, we have to double the other side. Expressions are built up from tiles corresponding to each of x 2, −x 2, x, −x, 1, and −1, where the shape and colour indicates the class of tile. For example, we can use square tiles to represent numbers. Solving Equations with Algebra Tiles Standards: 7AF4.1*: Solve two-step linear equations and inequalities in one variable over rational numbers, interpret the solution or solutions in the context from which they arose, and verify the reasonableness of the results. Six times the smaller is equal to 3 more than the larger. If we have 2x, then we will have two rectangle tiles. So that means our x is equal to 7. Solve the equation using algebra tiles and algorithms simultaneously. Example 1 : Use algebra tiles to model 3x - 4 = 5. This leaves us with just the green tiles on the left and our blue tiles on the right. You will need to flip the tiles to get the red inverse tiles. >>A paper version of the solving mat can be found for free here or here. Solve your equation using Graspable Math Create your Equation. We see our equals sign, so we will place square and rectangle tiles on either side to represent what is on either side of the equation. We have ten blue square tiles on the right side.
