Go Trick or Treating while you review many principles of decimals to the thousandths. This fun lesson is like a jeopardy game with a gameboard and linked slides. Each slide has a value and it can be played as a whole class divided into teams; as a small group; or even as partners in an independent center or station. Great for review or practice. Skills include place value with decimals; writing decimals, ordering decimals; measuring using decimals; greater than, less than, equal to with decimals. There is a variety of questions and questions are on different levels so they move from easier to more challenging as you choose a higher value of question. All slides are linked and answers are provided so entire lesson is self checking. Great for grades 3-7 depending on the level of the class. Halloween theme.
