Distributive Property Algebra Tile Models By Teaching In An Organized Mess An intro video: how to support students as they build on their understanding of the area model of multiplication to use algebra tiles to understand the distr. How to teach algebra: the distributive property progression with the area model (cra) “ditch the algebra tiles!”. many middle school and high school teachers will often eliminate the use of algebra tiles mathematical models or in many more cases not even introduce them at all causing them to promote “ditch algebra tiles”.
Distributive Property Algebra Tile Models By Teaching In An Organized Mess Students will add 8 2 to get 3 (10) and then multiply to get 30. you can have students discover that the distributive property allows for another way to solve. 3 (8 2) = 3 (8) 3 (2) = 24 6 = 30. proving to students that a property works instead of just telling them a property works will always earn a thumbs up from me. Engage in a similar discuss as above. write the expression 3(4x 2) on the board and ask students to represent the set as many ways as possible. represent the expressions 2(2x – 1) on the overhead with algebra tiles. ask students to represent the set in other ways and to write expressions that describe the set. I’ll use algebra tiles to show that two expressions that look different are actually equivalent.we're asked to show that 5(x 2) and 5x 10 are equal, or the s. Algebra tiles are great for modeling expressions, however, if you do not have algebra tiles you can either make them with paper, or use objects to represent the variables and constants. have your students model the expression. for example, they know that 2(x 3) means 2 groups of x plus 3. so now model the expression with manipulatives.
