It’s time to have a little fun decorating a colorful Christmas tree by using skills aligned with the Common Core State Standards Initiative. Today I’ve whipped up a Christmas Tree addition activity, where students can add ornaments, bells, Christmas lights, candy canes and more to a bare fir tree. Over the next few posts I’ll be adding Christmas tree activities for more skills – namely subtraction, multiplication and division – so that other grade levels can join in on the fun.

### Adding ornaments to the tree

Using this worksheet is easy – simply read the instructions, and then add that many indicated Christmas items to the undecorated Christmas tree. As you continue to add ornaments and other items to the tree, it will really start to sparkle. Don’t forget to use lots of different colors and patterns to decorate the tree!

### First and Second Grade Common Core Standards for Mathematics

This lesson falls under:

• 1.OA.5, Operations & Algebraic Thinking for first grade:

Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

• 1.OA.6, Operations & Algebraic Thinking for first grade:

Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.

• 2.OA.2, Operations & Algebraic Thinking for second grade:

Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
