This is a 1:1 correspondence activity! This packet includes counting mats for the numbers 0-20. There are 2 versions!! Version one is a spider web with spider counters and version 2 is a candy bag with candy counters!! Real manipulatives (spider rings or real candy) could also be used!!
Students choose a mat, say the number out loud and "fill" the web or candy bag with that number of matching counters!
