Complete this fun craftivitiy to consolidate teen numbers as a group of 10 and some ones. Either print off a set of teen numbers from this resource or print off the last page and have students write their own. Ideally, print on card or laminate afterwards. Print the lined page in a variety of blues.
Cut along the 2 dotted lines and thread through a piece of paper to create the first chain link. Continue so there are 10 links on the left side and as many links as ones on the right side.
This would make a great number display in your classroom.
