---- Learning the Building Blocks of Better Spelling and Vocabulary ----
Empowers students to acquire an unlimited vocabulary, preparing them for testing and higher education!

Students learn the meaning and spelling of Latin roots, prefixes, and suffixes that are the elements used to form words in English. Learning these word elements dramatically improves spelling and the ability to decode unfamiliar words.

The activities focus on using these words in context to help students incorporate each word into their vocabulary and retain the correct spelling. There are periodic reviews to make sure students retain what is taught in the lessons.

Word Roots apps will add hundreds of words to your students' vocabulary and greater depth to their thinking and writing.

Each lesson has the meanings of prefixes, roots, and suffixes used to form the vocabulary words. The activities in each lesson include:
A. Touch the Word That Matches the Definition
B. Touch the Word That Best Fits in the Sentence
C. Build the Word That Matches the Definition
D. Touch the Word Part That Matches the Definition

Loved this but...

Some reason every time we try to open it, it starts up as if we were setting up an account for the first time. It's like it can't remember the account we set up.

I used this program years ago on an old Mac OS and loved it. I was excited to see this in a mobile format so my younger children can use it, but some reason it's giving me account problems.

We count on this app for homeschool lessons but it’s lately crashing and freezing and not useable.
