This unit has a variety of activities that are easy to use and challenging. Great for grades four and five, but also good for accelerated third graders. The unit has a game called WILD 1, that is played like WAR or BATTLE. The unique and challenging feature to the game is that the largest number is not always the winner. The number with the greatest amount of factors wins. WILD 1 is the trump card because it only has one factor, itself. Students can play with a factor sheet, but as they become more comfortable with factors, the factor sheet answer sheet can be removed. This is a great game for the teacher to play against the class. HOTS are embedded in the activities. Students begin to recognize the frequency of "2" and "3" as factors. They form ideas about why some numbers have more factors than others.
Student task cards (10) are also included. These can be placed in a math center or the teacher can do them in whole group as a math warm up.
Two easy to use worksheets are included. Answer keys, also.
