teen numbers

K.CC.4 and K.CC.5  Counting and Cardinality (CC)  
K.NBT.1 Number and Operations in Base Ten (NBT)

We have been working on teen numbers and different ways to represent and show teen numbers. 

                                        

This teen number flyswatter game has been a favorite of my students.  I have the kids line up in two lines, they like to play girls vs. boys.  I call out a teen number and see who can swat it first.

                                                      

I created this sheet for students to work on showing a teen number in multiple ways, after we completed a lot of practice showing teen numbers on ten's frames, as ten blocks and ones, and counted items. We pick one number and fill out the whole sheet using that teen number.  This is a free download at teachers pay teachers.

                                         

We glued smarties on ten's frames to represent each number 1-20.  I hung this in the hall with the sayings "These smarties know numbers 1-20"
