Teach/Review writing numbers in word form.
Have students get into 4 groups.
Give each group an envelope with a variety of pictures. (I used magazines and old calendars.)
Tell students that they will have 3 minutes to choose a picture that they like. Remind them to not fight over pictures.
At the end of three minutes, have them take their pictures, return to their seats, and get out a piece of notebook paper.
Give students a couple of minutes to write down as many words as they can of things that are in their pictures or of things the pictures remind them of.
Provide students with copies of DIAL UP YOUR BRAIN. Demonstate how to convert their words into numbers.
Ask students to write their new numbers into word form.
