Whichever question they stall on names the lesson
The twelve questions above are drawn one skill at a time from these three lessons, which climb from counting outfits and codes to tree diagrams and picking without replacement. Each one teaches the method first, clicking through a worked example line by line, then works up through practice to a challenge.
Question numbers mean the same thing at every level, so whichever one your child stalls on names the lesson to work on next, whether they stalled at level 1 or level 3.
