Here is a new printable for the winter season: Mitten Count and Match. Download the cards by click the button below, then print and cut.
There are two cards representing each number. The children count the mittens on each card, and match the cards that have the same amount of mittens. The mittens are placed in different arrangements so that they do not appear the same at first glance. This way, children have to actually count them rather than match them by sight.
