Merry Christmas! To help your child stay sharp during the holiday, Santa has left lots of colorful presents filled with addition facts for your child to solve.

Santa's a busy guy. Help him out this holiday season by adding up his stash of candy canes, snowmen and presents!

Little math learners, get safely through the snow by filling in the missing numbers! This is a great activity to practice skip counting by twos.

Off to grandma's house for Christmas? Get there safely by filling in the missing numbers in these sequences. This is a tough skip-counting challenge!
