Esti Mystery Party!

The 2nd graders have been learning about numbers that are even and odd, numbers that are greater than or less than, and place value. 2nd graders placed beads in a brown paper bag, and their big buddies in 4th grade attempted to guess the mystery number of beads using clues provided by their little buddies. Clues included "my number of beads is an even number and has an 2 in the 10s place."
