5Number Talk
1. Aria is right: after 119 comes 120. Sample reasoning: 119 + 1 more = 120; the ones go 9 → 0 and the tens go up by 1 (1 ten becomes 2 tens).

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

3Show 118 Two Ways
1. Any two correct representations: base-10 blocks (1 flat + 1 rod + 8 units), 100 + 10 + 8, tally marks, ten-frames, etc.
4Number Talk
1. 120 has more tens: 120 has 2 tens, 114 has 1 ten. Look at the middle digit.

Common error: reading 120 as 'one hundred two.' Use base-10 blocks to show 2 full rods in the tens place.
