CHALLENGES IN LEARNING FACTORIZATION:
Students face difficulty in factorization as they lack clarity in factorization process, knowing identities, identifying like terms. One of the most common mistakes are cancelling incorrectly (eliminating common item from rational expression like x +2x +4= 4x +3) and inability to apply integer rule correctly.
WHY FACTORIZATION TILES?
Factorization tiles include red and purple tiles as positive and yellow tiles as negative with 3 different sizes of square as x2, Rod or rectangle as x and unit tiles as 1. While simplifying the equation student will be able to identify the like terms and discover which items to be consider as like terms and need to be cancel between equation. With concrete tiles students can solve the parenthesis problems of multiplication by method of area model. Different colored tiles help students to overcome problem regarding operation of integer rules and confusion about which sign to be carry out because they are visually able to observe the tiles that represent different sign and values.
