Starting up with Thing 2

Since Thing 1 has been "doing school" every day, Thing 2 has wanted her own work.  So, I bought her a little box and filled it with crayons, scissors and a glue stick.  She's been doing Kumon First Steps workbooks, two a day (we've done Let's Fold and Let's Color at the beginning of the year, then Let's Cut Paper and Let's Sticker and Paste.  Now We're on More Let's Fold and More Let's Color.).  However, she wants more.  Specifically, she wants the goodies for doing more.
At the completion of every book in their curriculum, the kids get an ice-cream party.  Since Thing 1 has switched from Shush and Say Six back to Aleph Champ, the the reward also includes a medallion for every book started.  Thing 2 also wants medallions.  So, I made a deal with her.  I said, "If you finish the first book, you'll get two medallions, red and white."  (Aleph Champ takes the Hebrew reading process and breaks it down into color-coded books--white, red, orange, yellow, green, blue, purple, and brown.  Thing 1 is on Blue.)  Thus far, it's been working.  Thing 2 does her page a day, and is so far up to the letter yud.  We'll see how it goes.
