Students explored 10s and 1s on the 120 chart by choosing a starting number, rolling a dice and then figuring out the direction to moved based on what the dice said. +10, +1, -10, -1
This is a tough concept to efficiently maneuver a 120 chart but it was lots of fun. In time, students will make the connection that moving up and down on the chart is changing the number by 10 and moving left to right is how to move by 1s.
