Grown-up sheet · Level 3 · Hundred Island · Big game
This is the fifth island of Level 3: counting on from any number, crossing into the next ten, counting to 100, and counting by tens and by twos.
How to use it
- Watch the video together with your child. Don't give them the answer. If they stay quiet, wait for Pipo to say it.
- For each challenge, mark just one box:
- ✓ if they answered on their own, before the circle emptied.
- ½ if they answered late or with help.
- ✗ if they didn't answer or got it wrong.
- Pause the video to write things down if you need to.
- At the end, look at the "What to review?" table.
What to watch for on this island:
- Counting on without going back to one: with "25, 26, 27, ?", ideally they keep going from 27. If they count from one to get there, they aren't counting on yet.
- Crossing into the next ten: the hard step is from 29 to 30 or from 49 to 50. Mistakes like "twenty-ten" or "forty-ten" are common.
- Counting by tens or by twos: notice whether they count the bars saying "ten, twenty, thirty" or count them dot by dot.

What to review?
Rule: a block is mastered if the child got at least one challenge with ✓ and none with ✗.
| · | Counting on 1–2 | Stop 1: "Learn" and "Play" (M19-S1-A, M19-S1-J1) and "Learn" from stop 3 (M19-S3-A) |
|---|---|---|
| · | Counting by tens 3–4 | Stop 2: "Learn" and "Play" (M19-S2-A, M19-S2-J1) |
| · | Up to one hundred 5–6 | Stop 3: "Play" and "Play more" (M19-S3-J1, M19-S3-J2) |
| · | Counting by twos 7–8 | Stop 4: "Learn" and "Play" (M19-S4-A, M19-S4-J1) |
| · | Pipo made a mistake! 9–10 | Stop 5: "Learn" and "Play" (M19-S5-A, M19-S5-J1) |
What to do next:
- Everything mastered: move on to the next island (measuring and time).
- One block not mastered: rewatch those videos for 2 or 3 days.
- Two or more blocks not mastered: it's worth spending one more week on this island. Counting to 100 takes time, and reviewing is fine.
Common mistakes at this age:
- "Twenty-ten" (challenge 2): count together on a 1-to-100 chart and point to the jump to the next row: "after nine, the next row."
- Mixing up 73 and 37 (challenge 6): say the number slowly, "seventy… three". The first digit tells you the tens.
- Counting the bars dot by dot (challenge 3): it isn't a mistake, but it takes longer. With pasta or sticks in piles of ten, practice "ten, twenty, thirty".
