Classifying Polynomials
I can write a polynomial in standard form and name its degree and number of terms.
The problem this sheet solves
Degree is the HIGHEST exponent anywhere in the polynomial, not the one that happens to appear first, and students who read left to right get it wrong whenever the polynomial is not already in standard form. Naming by number of terms is the companion skill, and it collapses in the same way once the ordering is unfamiliar. This sheet makes standard form the move that PREVENTS the error rather than a separate tidying step, because once the highest power leads, the degree cannot be misread. Classifying by degree and by term count is practised together, and polynomials are deliberately presented out of order.
The key rule
The degree is the HIGHEST exponent anywhere in the polynomial, not the exponent you happen to read first. Put it in standard form and the highest comes to the front.
Scan every term. Then order it.
Watch out
The mistake: For 5x + 3x4 − 2 a student answers degree 1.
The fix: Degree 4. The 5x is only first, not highest. In standard form it reads 3x4 + 5x − 2, and the degree is then impossible to misread.
