## Makey Takey: Place Value

This kit is designed for use in a center with a 1st grade class to address the NY Common Core Math standard 1.NBT.2: Understand that the two digits of a two-digit number represent amounts of tens and ones. During this lesson, students will determine which pressure switch activates each place value and put them in the correct order. Students will be given a two- or three-digit number (by the teacher), and students will activate the correct pressure switches to arrive at the correct number in the pre-created Scratch program.
