Practice weighted like the test

Practice that gives every standard the same number of questions spends too long on standards that carry little of the test. These sets follow the weighting TEA publishes instead.

Assign each reporting-category set as you teach it, then give the practice test once everything has been taught.

Teacher questions

When should I use each part?

Assign each practice set as you teach its topics, then give the full-length practice test once everything has been taught.

What about calculators?

The practice follows the state's calculator rule for this grade: graphing calculator required. Check your school's testing guidance for the current rules.

Are these actual state test questions?

No. Every item is original and aligned to the published standards. Nothing is copied from a state test, a released item or a reference sheet.
