Fast, Easy, and Engaging! The 20th century Texas speed sheets includes all of the major events of the 20th Century. The speed sheets are aligned with the Texas Knowledge and Skills for Seventh Grade. Speed Sheets allow students to learn the significant content vocabulary without spending an entire class period on an activity. Speed Sheets provide an activity for each day of the week that allows the teacher to facilitate and pre-teach vocabulary concepts throughout a unit of study. By pre-teaching the vocabulary, students have a foundation to connect the significant ideas, people and events within the curriculum.
