tree1
Help me figure out how many ornaments it will take to decorate my tree.  I put a star on the top of my tree and string garland around the tree.  The garland separates the tree into sections for me to decorate.  The top section uses 1 ornament and the next section uses 3 ornaments.  The third section down uses 5 ornaments as the tree gets wider and wider.  If this pattern continues, how many ornaments altogether will it take to decorate my tree?
Hint: I count 6 sections on my tree.










For 4th and 5th graders:  If each box of ornaments contains 12 ornaments and costs $6.00 a box, how much will it cost me to buy ornaments?
