About Word Roots Level 3 Flashcards™

Word Roots Level 3 Flashcards™

The Building Blocks of Better Spelling and Vocabulary

Word Roots Level 3 Flashcards™ can be used with our award-winning Word Roots books/software products or as an independent teaching tool.  The 10 flashcard games in this software teach students the meanings of word parts (prefixes, roots, and suffixes) so they can decode the meaning and spelling of new vocabulary by breaking a word into its word parts.  This set of games includes all of the 23 prefixes, 115 roots, 23 suffixes, and 288 vocabulary words that are in the corresponding book or software.

The games are numbered 1-10.  Games 1-6 are Study Games to learn the word parts and their definitions.  Games 1-3 and 4-6 can be switched and the prefixes, roots, or suffixes can be played in any order.  Games 7-10 are Practice Games using the word parts to form words to show that students know the definitions of the word parts.  Games 7 and 8 may be switched with games 9 and 10.

We have numbered the games in what we consider the optimal learning order, but you also have the option to create your own order to meet your needs.  For example, rather than do all of the flashcards by identifying the definition or word part, you may choose to focus on studying prefixes, then suffixes, then roots.

For more than 50 years, our fun, award-winning products have helped students of all abilities achieve better grades and higher test scores with highly effective lessons that sharpen the mind as they teach reading, writing, mathematics, science, and history.  We do not teach through drill and memorization or teach to the tests - we empower the mind!

We design critical thinking into our products so students must carefully analyze what they are learning.  Deeper analysis produces deeper understanding, which results in better academic performance.  Over time, students who practice critical thinking learn to apply it throughout their education and life.

“If we teach children everything we know, their knowledge is limited to ours.
If we teach children to think, their knowledge is limitless.”
