Tricky Teens

Numbers 10-14

Numbers 15-19


Over the past two days we have been exploring the tricky teens.  We've talked a lot about how numbers in the teens are made up of "a ten and some ones."  We made chains with links; each student made a ten out of black links.  Then, each student made a different number from their ten by adding orange links.  12, for example, was 1 black ten and 2 orange ones.  Next we are going to label our tricky teens and hang them up in the room.  That means we get to enjoy our numbers, see a growing number line AND decorate our classroom for Halloween!
