  • Effective vocabulary instruction strategies actively engage the student and require higher-level cognitive processing.  These strategies include: using new words in novel sentences based on connections to prior knowledge, identifying synonyms and antonyms, analyzing word features, and using visual aides (Kester-Phillips, Foote, & Harper, 2008).
  • Students need to understand semantic connections among words.  It may be necessary to target understanding of basic concepts that underpin the vocabulary required to access the curriculum (Taylor-Goh, 2005).
  • In-depth knowledge of word meaning helps students comprehend what they read and helps them use words accurately in speaking and reading (Taylor-Goh, 2005).
  • Vocabulary intervention should provide opportunities for students to use target words in multiple contexts (Boone et al., 2007).

100% Concepts incorporates these principles and is also based on expert professional practice.

Children need an adequate grasp of concepts to succeed in school and everyday life.  The essential concepts for each grade build in successive grades.  Missing out on these concepts causes a student to fall further and further behind.  That is why we put together worksheets on primary and higher-level concepts that students in elementary grades need to know.  Our intent is not to teach these concepts from the ground up; rather we've written worksheets that apply the concepts to the curriculum your students face every day. 

We've chosen concrete concepts, grouped them by topic area, and given the learning a curricular twist. 

In each section, we've included teacher guide pages with suggestions for teaching each concept.  You'll also find an index of all concepts and an answer key in the back of each book.  Please note that answers given are representative of probable student responses, so accept any other reasonable responses your students might give.    

We hope you'll have as much fun using the books as we did writing them.  Enjoy!
