Hold the Ctrl key down while dragging a tile which also makes a copy of the original. I show how using Algebra Tiles can make this process easier to see in the two videos below. Instruct students to model each expression with the tiles draw the model simplify the expression and write the simplified answer.
For all real numbers a b and c if a b then. Variable squared squares were 7cm x 7cm. I really like to annotate what I am doing as I work.
Make a rectangular array of the tiles by placing square tiles in the upper left corner and unit 1 tiles in the lower right corner. The first step is to copy the tiles above to model the equation. I have used conventional x rather than b.
Solve ½x 4 7 with algebra tiles. Read the dimensions factors of the completed triangle. Variable rectangles were 15cm x 7cm.
Solving a simple linear equation using Algebra Tiles. Solve 3x 15 using Algebra Tiles. Division Perfect Squares and Completing the Square In this the last post of the Algebra Tiles series I will be looking at how you can use the tiles to demonstrate various more advanced ideas such as difference of two.
The Division Property of Equality states. First lets review dividing whole numbers by whole numbers. We still keep the other half for the end First I cut an x in half to show the ½x.
For each product sketch the tiles you could use. The black bar stands for the equal sign. Factorising a quadratic expression where the coefficient of x is not 1 Factorising a quadratic expression where the coefficient of x is not 1 another example.
You might also want to give the students a laminated A3 sheet to work on so they can annotate and write notes as they use the tiles. Its nice to use paper algebra tiles free here for this example so that an x can be cut in half. Assessment Questions o Draw a model of the division of a trinomial with a binomial.

I 12k 4 ii -12k 4 iii 12k iv - 12 k -4 b In part a two of the products were b In part a explain why some answers are not modelled by the algebra tiles. Throughout the integer operation series we have focused only on adding and subtracting integersNow that students have developed a solid understanding of how integers work we will continue the series by introducing the multiplication of integersYES finally onto multiplying negative and positive values as many have requested to date.
Solving Equations in One Variable Model the left and right side of the equation. We will soon see that dividing whole numbers by unit fractions has the same meaning 6 div 3 means. In the video below I show how I would solve the above problem using Algebra Tiles.
