Materials:
-A collection of 25-100 items for students to count (shoes, buttons, crayons, etc.)

Directions:
·      Pose the questions “how could we count these in a way that’s easier than counting by ones?”
·      Use whatever suggestions you get as best you can
·      After trying a few different ways, talk about what worked best and what didn’t work as well
·      If no one brought up counting by tens, suggest it

Pretzel stick place value


Materials:
·      Laminated place value mats for each student
·      Numbers for teacher to hold up

Directions:
·      Give each student a place value mat and a pile of pretzel sticks
·      Draw a number card and read it aloud (also hold it up for the students to see)
