Word Study – Latin Root family cent + KeyLanguage Montessori-inspired Worksheet

Explore the origins of modern English. 

Word study is the study of the changes made to words over time as our language has developed. Etymologies are not definitions but rather explanations of how our words came to be and how they might have sounded many years ago. It is both an extension of vocabulary enrichment as well as an aid to spelling. 

Word study can begin in the primary with affixes and compound words, but should extend into the elementary with word families, synonyms and antonyms.

Coordinate Geometry refers to graphing (or plotting) and analyzing points, lines and areas on a coordinate graph.

Grammar Symbols – Language Montessori-inspired Worksheet

Grammar is the essence of our language. Our words enable us to put forth our thoughts to others in a way that can be understood. It is the study of the way sentences are constructed. Syntax is the arrangement of words and phrases to create well-formed sentences in a language.

Grammar centers around the verb and the noun – the two most parts in our language. Other parts of speech have a relationship to one or the other of these two. 

The colors chosen for each are simply used to symbolize their function. There is no other meaning.

Multiplication Table x 10 Blank – Mental Math Montessori-inspired Worksheet

How You Can Help Your Child at home:

  1. Be interested in math yourself. You are your child’s greatest role model!
  2. Find out what facts they already know. Spend the least amount of times on these.
  3. Focus primarily on the facts they need to learn; kids tend to struggle with 6s, 7s, 8s and 9s.
  4. Provide encouragement along the way; you could even use a chart to monitor progress.
  5. Spend quality time practicing together and remember to acknowledge their successes!
