2008 TAKS
Notes
• These questions came from the TAKS grades 5, 8, 10 and 11 tests. Difficulty varies from “easy squeezy” to “gonna have to think”.
• There are numerous good questions that simply have too much to put on a slide – large graphics and/or lots of text. To access the test to print:– http://ritter.tea.state.tx.us/student.assessment/re
