Readroots is a series of 100 vocabulary-building units that help students learn important Greek and Latin roots and affixes. We made 100 units so that teachers in sequential grade levels can work together to present coherent and effective vocabulary instruction over time. The units are organized into twenty sets of five, so a fourth grade teacher might present the first 20 to 25 units, a fifth grade teacher might present the second 20 to 25 units, etc. Each unit incorporates images and a variety of collaborative activities that provide repeated opportunities for students to practice using the roots and affixes in different contexts.
Each unit requires students to learn just six parts, but the six parts work together to create lots of words. The six parts of Unit 1, for example, are the prefix “re_,” four roots (“pel/pul/puls,” “quer/quir/quest” “volv/volvo/volu/volt,” “mot/mov/mob”), and the suffix “_tion/_ion.” With these parts, students can construct the words: repel, repulse, request, require, question, revolve, revolt, revolution, remote, remove, and motion. Readroots is designed such that subsequent units connect directly with and build on the parts of previous units. Unit 2, for example, teaches: “de_,” “flex/flect,” “tect,” “press,” “ceiv/cep/cept,” and “fend/fens.” Students can now build: demote, devolve, reflex, reflect, reflection, repress, repression, receive, reception, deflect, deflection, detect, detection, depress, depression, deceive, deception, defend, and defense.
