Unlike the 5th grade boks starting in 6th grade the vocabulary is not listed in the beginning of each Investigation. I will be posting the vocabulary for the whole unit and having the students copy the vocabulary into their copybooks when we start a new unit. The students will have two weeks to study the vocabulary words before they are tested. Please make sure your child studies the vocabulary words for the unit each night until they have the test.
