Now, stand so that the door is to your left. Students should respond with an estimated number of feet. Students should respond with both the estimated number of feet and a direction. But, when I asked where the door was in relation to my position, you gave me a direction as well as a number, and then it did matter which way I was facing. Today, we'll talk about absolute value.
Absolute value tells how far from zero a number is.
It doesn't tell you which direction from zero. Point to 6 on the number line. Divide the class into two teams. Encourage students to be creative with their questions. Team 2 should go first as often as Team 1 does.
