- Left: 3 girls sitting
- Right: 2 girls standing
→ 3 + 2 = 5

Row 2: Ice cream cones

- Right: 3 swirled ice creams
→ 4 + 3 = 7

Row 3: Cupcakes
- Left: 2 plain cupcakes with cherries
- Right: 2 pink-frosted cupcakes

- Right: 3 carrots grouped together
→ 5 + 3 = 8

Row 5: Mangoes
- Left: 2 yellow mangoes

- Right: 1 watermelon
→ 1 + 1 = 2

Row 7: Airplanes
- Left: 5 red/blue planes
- Right: 6 white/red-striped planes

Row 8: Hot air balloons
- Left: 2 colorful balloons
- Right: 1 balloon
→ 2 + 1 = 3

Row 9: Monkeys
- Left: 6 monkeys (some standing, some sitting)
- Right: 4 monkeys playing
→ 6 + 4 = 10

Row 10: Boxes with ball

- Right: 1 empty box → that’s also 1 item
→ 1 + 1 = 2
