2. Can find the product of any two Polynomials by formal multiplication

Activity No #1

Multiplying Polynomials Using Algebra Tiles

• Estimated Time

15 to 20 minutes

• Materials/ Resources needed

1. Algebra Tiles activity sheet , 2. Algebra tiles

• Prerequisites/Instructions, if any

Knowledge Of the terms monomial, binomial, trinomial, polynomial, term, degree, base, exponent, coefficient

• Multimedia resources

• Website interactives/ links/ / Geogebra Applets
• Process/ Developmental Questions

1. Demonstrate multiplying polynomials using algebra tiles, as shown in above video :

(x x 1)(x + 6) = x2 + 7x + 6

2. Distribute algebra tiles and copies of the Multiplying Polynomials Using Algebra Tiles activity sheet. Instruct students to model each expression with the tiles, draw the model, simplify the expression, and write the simplified answer.

• Evaluation

o Draw a model of the multiplication of two binomials. Simplify your expression.

o Explain why (2x)(3x) = 6x and not 6x.
