We need to write the number that matches each word form.
- Twenty nine → 29
- Eighty four → 84
- Thirty six → 36
- Three hundred & nineteen → 319
- Fifty two → 52
- Eight hundred & seventy → 870
✔ All correct.

Addition:
Solve each addition problem.
Left column:
1. 22 + 9 =
31
2. 44 + 7 =
51
3. 8 + 33 =
41
4. 6 + 19 =
25
5. 15 + 11 =
26
6. 27 + 12 =
39
Right column:
7. 50 + 30 =
80
8. 10 + 80 =
90
9. 70 + 20 =
90
10. 30 + 60 =
90
11. 10 + 30 =
40
12. 50 + 20 =
70
✔ All additions verified.

Shade odd numbers:
Odd numbers are not divisible by 2 — they end in 1, 3, 5, 7, or 9.
List all numbers and pick the odd ones:
Row 1: 89 (odd), 95 (odd), 45 (odd), 128 (even), 44 (even), 43 (odd), 35 (odd)
→ Shade: 89, 95, 45, 43, 35
Row 2: 26 (even), 22 (even), 21 (odd), 17 (odd), 19 (odd), 88 (even), 24 (even)
→ Shade: 21, 17, 19
Row 3: 36 (even), 62 (even), 11 (odd), 9 (odd), 12 (even), 130 (even), 127 (odd)
→ Shade: 11, 9, 127
Row 4: 197 (odd), 175 (odd), 188 (even), 125 (odd), 74 (even), 72 (even), 66 (even)
→ Shade: 197, 175, 125
✔ Total shaded odd numbers:
89, 95, 45, 43, 35, 21, 17, 19, 11, 9, 127, 197, 175, 125

How many tens and ones?
Break each number into tens and ones.
Example: 88 → 8 tens and 8 ones
1. 88 → Tens =
8, Ones =
8
2. 39 → Tens =
3, Ones =
9
3. 41 → Tens =
4, Ones =
1
4. 59 → Tens =
5, Ones =
9
5. 73 → Tens =
7, Ones =
3
✔ All place values correct.
