Meet Mr. Origin
Est. Class Sessions: 1–2
Students use the manipulative Mr. Origin to describe the location of objects with directional descriptors: right, left, front, and back. They first play “Mr. Origin Says,” a variation of the game “Simon Says” in which they position Mr. Origin relative to various classroom objects. Students then describe the location of objects along the horizontal axis by measuring the distance and describing the direction they are from the origin or from each other.

Materials Preparation
Prepare Mr. Origin. Copy the Mr. Origin Master on heavy paper or card stock so you will have one Mr. Origin for each student. Cut apart, fold, and tape the front and back together so each Mr. Origin stands.
Create Mr. Origin’s Map. Make a model of Mr. Origin’s Map illustrated on the Mr. Origin’s Map page in the Student Activity Book. See Figure 1. Tape two centimeter rulers to a piece of chart paper or display for the axis. Place a prepared Mr. Origin and the four pattern blocks (hexagon, blue rhombus, square, triangle) along the axis of the model.

TIMS Tip
On some Mr. Origins, the right hand is larger than the left hand; on others, he is wearing a mitten. If you feel the right hand on your Mr. Origin is not distinct enough, place some tape on the right hand.
