Large Group (Maria):

 * Introduce idea of writing subtraction equations for Total of Ten instead of addition. (ie. if you find the combination 7 and 3 to make 10, you can write 7+3=10 but you can also write 10-7=3 or 10-3=7.) Also, show how to include the subtraction equation in the Trading Game recording sheet.
 * Students play Total of Ten and the Trading Game going backwards in pairs (half and half)

Small Group (Heidi):

 * Play Collect 25 cents
 * Make 23 using base-ten blocks.
 * Use plus-1 flashcards to review plus-1 facts, with ten-frames as well.
