5Number Talk
1. Aria is right: after 109 comes 110. Sample reasoning: 109 + 1 more = 110; the ones go 9 → 0 and the tens go up by 1.

If your child says 'one hundred AND two,' gently model 'one hundred two' — no 'and' in standard form.

3Show 108 Two Ways
1. Any two correct representations: base-10 blocks (1 flat + 8 units), 100 + 8, tally marks, ten-frames, etc.
4Number Talk
1. 110 has more tens: 110 has 1 ten, 104 has 0 tens. Look at the middle digit.

Common error: writing 107 as '1 hundred 7 tens.' Use base-10 blocks to show the tens place is EMPTY (zero tens).
