The definition of an appositive is a little bit complicated. Here are quite a few examples of appositives. Basically it is when you add a definition next to the noun to help clarify what it means. For example:
Mrs. Johnson, Billy's English teacher, said that he needed to write more neatly.
Thermodynamics - remember to tell your kiddos that thermo means heat and dynamics means movement - so we are talking about the way heat moves here. Big word, simple idea!
There is a fun series of math books by Cindy Neuschwander that deals with math ideas. The one we read this week is Sir Cumference and the First Round Table, there is also Sir Cumference and the Dragon of Pi (we might check this one out this week), There are many other titles. I don't know that I would buy the books but they are great to check out and read.
One of the things we should make more use of in our house is our world map shower curtain. It is really great to have a huge map that all my kids can look at easily and that they see everyday. I think we got it at Target once upon a time and as we get into these smaller countries - they still look pretty big when the map is the size of a shower curtain.
Have a great week.
