Watch the linked video of Jess and Squeaks Build a Back Scratcher again if needed. Jess has a problem that she needs your help to solve. She needs you to CREATE the back scratcher and then to TEST it on one of your teachers' backs and your partner's back to see if it scratches their backs well. If it does not, then you will need to IMPROVE the back scratcher and TEST again to see if it is better than your first one. Remember to draw the pictures of what you created and what you improved. 1. Tap 2. Take a photo of your planning sheet again and your creations. 3. Tap and record what happened after you tested the back scratcher and tell us whether it worked or didn't and why. What would you do differently the next time?
