Problem 1: Circle the odd numbers below.

Odd numbers end in 1, 3, 5, 7, or 9.

Look at each number:

Row 1:
- 16 → ends in 6 → even
- 255 → ends in 5 → odd
- 8 → ends in 8 → even
- 42 → ends in 2 → even
- 37 → ends in 7 → odd
- 89 → ends in 9 → odd
- 630 → ends in 0 → even
- 10 → ends in 0 → even

Row 2:
- 94 → ends in 4 → even
- 77 → ends in 7 → odd
- 36 → ends in 6 → even
- 448 → ends in 8 → even
- 81 → ends in 1 → odd
- 19 → ends in 9 → odd
- 543 → ends in 3 → odd
- 48 → ends in 8 → even

So the odd numbers are:
255, 37, 89, 77, 81, 19, 543

Problem 2: Circle the even numbers below.

Even numbers end in 0, 2, 4, 6, or 8.

Row 1:
- 84 → ends in 4 → even
- 43 → ends in 3 → odd
- 38 → ends in 8 → even
- 920 → ends in 0 → even
- 71 → ends in 1 → odd
- 62 → ends in 2 → even
- 346 → ends in 6 → even
- 95 → ends in 5 → odd

Row 2:
- 11 → ends in 1 → odd
- 32 → ends in 2 → even
- 472 → ends in 2 → even
- 23 → ends in 3 → odd
- 527 → ends in 7 → odd
- 58 → ends in 8 → even
- 90 → ends in 0 → even
- 47 → ends in 7 → odd

So the even numbers are:
84, 38, 920, 62, 346, 32, 472, 58, 90

We’ll list which are even (blue) and which are odd (red).

Grid:

Row 1:
- 34 → even → blue
- 45 → odd → red
- 38 → even → blue
- 437 → odd → red
- 24 → even → blue
- 372 → even → blue
- 358 → even → blue

Row 2:
- 50 → even → blue
- 29 → odd → red
- 734 → even → blue
- 531 → odd → red
- 33 → odd → red
- 50 → even → blue
- 59 → odd → red

Row 3:
- 452 → even → blue
- 326 → even → blue
- 42 → even → blue
- 39 → odd → red
- 451 → odd → red
- 946 → even → blue
- 129 → odd → red

Row 4:
- 18 → even → blue
- 97 → odd → red
- 208 → even → blue
- 55 → odd → red
- 7 → odd → red
- 98 → even → blue
- 47 → odd → red

Row 5:
- 6 → even → blue
- 3 → odd → red
- 22 → even → blue
- 83 → odd → red
- 30 → even → blue
- 774 → even → blue
- 342 → even → blue
