Fractions

What you'll learn

• Identify algebra tiles representing x², x, 1, -x², -x, and -1, and correctly associate them with their corresponding algebraic terms in polynomial expressions with 100% accuracy.
• Model polynomial expressions (up to degree 2 with integer coefficients) using algebra tiles, representing at least 4 different polynomials accurately, as assessed by a teacher checklist.
• Simplify polynomial expressions (up to degree 2 with integer coefficients) by combining like terms using algebra tiles, and accurately record the simplified expression in standard algebraic notation, achieving at least 80% accuracy on a practice worksheet.
• Explain the process of combining like terms in a polynomial using algebra tiles, justifying each step with the properties of addition and subtraction, in a written paragraph that demonstrates understanding based on a provided rubric.
