Make the bars green! How? Put your left index on the left bar, your right index on the right bar, and move the fingers up and down.  o The right finger needs to move double the speed of the left hand.  Click the arrow to make the bars go up and down in green.  See if these numbers help you move between green combinations.  they found a “green” pair, then moved both fingers up, but the bars went red.  Are your shapes green? Study the table: figure out shortcuts for predicting green number pairs.  o The fingers need to move in different ways.  What's new? Have you discovered a new technique? You can change the calibration of these lines by pressing on the arrow in the bottom-right-hand corner.  Developed by Berkeley professor of mathematics education, this is an innovative entry to the concept of proportion.  This brings up multiple meanings of ratio and proportion and helps everyone build connections.  o The distance between the fingers needs to grow as you go up.  These horizontal lines could help you find “green” locations.  Contrast with non-proportional situations such as two siblings' ages now and when the younger one is double as old.  Same game, but now you get to input numbers in a ratio table.  o It's about the relation between where the two fingers are at.  Use Settings to create your own secret ratios for the four conditions.  Have your students discuss their strategies.  Finally, click “D”.  Next, click on “C”.  Now click “B”.  o For every 1 unit you up on the left, you go up 2 on the right.  Look on the left: You've been working on “A”.  o Ask students what was surprising for them.  strategies give the same outcome.  time on a bike(kid) and car (parent).  it in middle school.  Play with this for a while.
