I used this in Kindergarten for a beginning review for five minutes as a review for what we taught the following week. It is based on the common core with boxes labeled accordingly. I did four days together and on the fifth day was a quiz. You can also use this for center work or homework. I used this on the Smartboard and the students completed this for one minute individually. Then, they worked in pairs. We went over this for a few minutes. Mainly, this is used as review.
