Missing Addends Christmas Math Center for first grade! Use this cute Christmas cookie themed center activity to practice finding the missing addends. The center includes a cookie sheet part-part-whole work mat with red and white Christmas cookie game pieces that students use to work out the problem and find the missing addend using concrete manipulatives.

Center includes five different practice sheets with missing addend problems with a given number of red cookies. Students use the cookie piece manipulatives on the work mat to find the missing number of white cookies for each problem and record their answers on the practice sheet.

Center requires some minimal prep (laminate work mat and center pieces) and offers cute, seasonal practice with this critical building block in mathematical understanding! Merry Christmas, and I hope your kiddos enjoy this activity!
