"Quantities Discrimination Worksheet: Students write the number under each image to practice counting and number recognition."

Let's solve this Quantity Discrimination worksheet step by step. The goal is to count the number of items shown in each box and write the corresponding number in the blank space below it.

We’ll go through each box row by row:

---

Row 1

1. Hand showing 5 fingers → 5
2. Dice with 3 dots → 3
3. 6 green dots (in a 2×3 grid) → 6
4. Hand showing 5 fingers → 5

✔ Row 1: 5, 3, 6, 5

---

Row 2

1. 10-frame with 10 blue dots filled → 10
2. 4 vertical lines (tallies) → 4
3. Two dice: one with 6 dots, one with 6 dots → 6 + 6 = 12
4. Dice showing 3 dots → 3

✔ Row 2: 10, 4, 12, 3

---

Row 3

1. Hand showing 1 finger → 1
2. Tally marks: four vertical lines and one diagonal crossing them → This is a group of 5 (standard tally mark group)
- But here, there are four vertical lines, and then two more next to it? Wait — actually, let’s look:
- It shows: `||||` (four vertical) and then two more `||` beside it?
- No — wait: It looks like five tally marks: four vertical and one diagonal across them → that’s 5
- But wait — it says `| | | |` and then two separate `||` — no, looking closely: it's one group of five with a diagonal line through four vertical lines — yes, that’s standard 5
- So total: 5
- Actually, on closer inspection: It appears to be five tally marks: four vertical and one diagonal through them → 5
- But the image shows: `||| |` and then `||`? No — actually, it's drawn as:
- Four vertical lines (`||||`) and then one diagonal line crossing them → that makes 5
- So 5
2. 10-frame with 3 purple dots → 3
3. Grid with 8 green dots (2 columns of 4) → 8

✔ Row 3: 1, 5, 3, 8

---

Row 4

1. One purple vertical line → 1
2. Hand showing 2 fingers → 2
3. Dice with 4 red dots → 4
4. Two dice: one with 5 dots, one with 3 dots → 5 + 3 = 8

✔ Row 4: 1, 2, 4, 8

📝 Explanation:

This activity helps children develop quantity discrimination — the ability to recognize how many items are in a set without counting (subitizing), or by counting accurately. The representations vary:
- Hands
- Dice
- Tally marks
- Ten frames
- Dots in grids
- Lines

Each representation shows a quantity, and the child must match it with the correct numeral.

✔ Final Answer: Write the numbers as shown above in the blank boxes.
