READ

The school garden has 24 rows of vegetable plants. If each row contains 13 plants, how many plants are there in total in the garden?

BUILD

The initial stamp game setup should show:

First factor: 24 (2 blue ten stamps and 4 green unit stamps)
Second factor: 13 (1 blue ten stamp and 3 green unit stamps)

DRAW

Complete solution process with stamp game:

Step 1: Arrange the first factor (24) with 2 blue ten stamps and 4 green unit stamps
Step 2: Arrange the second factor (13) with 1 blue ten stamp and 3 green unit stamps
Step 3: Multiply units × units: 4 × 3 = 12 (exchange for 1 blue ten stamp and 2 green unit stamps)
Step 4: Multiply tens × units: 2 tens × 3 = 6 tens (6 blue ten stamps)
Step 5: Multiply units × tens: 4 × 1 ten = 4 tens (4 blue ten stamps)
Step 6: Multiply tens × tens: 2 tens × 1 ten = 2 hundreds (2 red hundred stamps)
Step 7: Combine all results: 2 hundreds + (6 + 4) tens + 2 units = 2 hundreds + 10 tens + 2 units

Final Answer: 312 plants

Explanation: To find the total number of plants in the garden, we multiply the number of rows (24) by the number of plants in each row (13). Using the stamp game, we calculated partial products and combined them to get our answer of 312 plants.

CONTROL CARD: DIVISION - Problem #2

Solution Guide

READ

A baker has 8.4 kg of flour. They use 0.35 kg for each loaf of bread. How many complete loaves can they make with the available flour?

BUILD

The initial stamp game setup should show:

Dividend: 8.4 (8 green unit stamps and 4 green tenth stamps)
Divisor: 0.35 (3 green tenth stamps and 5 blue hundredth stamps)

DRAW

Complete solution process with stamp game:

Step 1: Convert dividend to 8.40 (8 green unit stamps, 4 green tenth stamps, 0 blue hundredth stamps)
Step 2: Convert to equivalent whole numbers: 840 ÷ 35 (removing decimal points)
Step 3: Set up 840 using stamp game (8 red hundred stamps, 4 blue ten stamps, 0 green unit stamps)
Step 4: Determine how many times 35 goes into 840:
- 35 goes into 84 (the first two digits) 2 times: 2 × 35 = 70
- Subtract 70 from 84, leaving 14
- Bring down the 0: 140
- 35 goes into 140 exactly 4 times: 4 × 35 = 140
- No remainder
Step 5: Record the answer: 24

WRITE

Complete written solution:

Mathematical Equation: 8.4 ÷ 0.35 = ?

Algorithm 1: Long Division with Decimal Adjustment To handle the decimals, first convert to equivalent whole numbers: 8.4 = 8.40 = 840 (multiplied by 100) 0.35 = 35 (multiplied by 100) So: 8.4 ÷ 0.35 = 840 ÷ 35

Algorithm 2: Repeated Subtraction 8.40 ÷ 0.35 = 840 ÷ 35 840 - 35 = 805 (1) 805 - 35 = 770 (2) 770 - 35 = 735 (3) [Continue process] 210 - 35 = 175 (19) 175 - 35 = 140 (20) 140 - 35 = 105 (21) 105 - 35 = 70 (22) 70 - 35 = 35 (23) 35 - 35 = 0 (24)

It takes 24 subtractions to reach 0, so the answer is 24.

Algorithm 3: Equation Method 8.4 ÷ 0.35 = n 8.4 = 0.35 × n 8.4 = 0.35n 8.4/0.35 = n 24 = n

Algorithm 4: Fraction Method 8.4 ÷ 0.35 = 8.4/0.35 = 84/10 ÷ 35/100 = 84/10 × 100/35 = 8400/350 = 24

Final Answer: 24 complete loaves

Explanation: To find the number of loaves, we divide the total amount of flour (8.4 kg) by the amount needed per loaf (0.35 kg). After converting both values to the same decimal places and removing the decimal points for easier calculation, we found that the baker can make exactly 24 complete loaves with the available flour.

🟦 Task/Command Card: Multiplying Decimal Fractions Using Montessori Stamp Game

Problem:

Sofia is making goodie bags for her party. She puts 3.2 ounces of candy into each bag. If she fills 4 bags, how many ounces of candy will she use in total?

🔵 Step 1: READ

Read the problem aloud. What do you know? What do you need to find?
How many ounces per bag?
How many bags?
What operation will we use?

✅ We are multiplying a decimal (3.2) by a whole number (4).

🟢 Step 2: BUILD (Montessori Stamp Game)

Use the Montessori Stamp Game:

Represent 3.2 using 3 green unit tiles and 2 gray tenth tiles.
Set up 4 rows for 4 groups.
Place 3 units and 2 tenths in each row.
Now, count all tiles across the four rows:

Units: 3 × 4 = 12 green unit tiles
Tenths: 2 × 4 = 8 gray tenth tiles

Exchange:

12 green units → 1 blue ten + 2 green units
8 gray tenths stay as is.

🧮 Total: 1 ten (blue) + 2 units (green) + 8 tenths (gray) = 12.8 ounces

🟠 Step 3: DRAW

Draw the stamp tiles and groupings. Use color-coded squares:

🔴 Red = hundreds
🔵 Blue = tens
🟢 Green = units
⚪ Gray = tenths

SVG CODE:

<text x="10" y="70" font-size="14" fill="black">Group: 1 of 4</text>

</svg>

(Repeat or extend drawing for 4 groups)

🔴 Step 4: WRITE

Now try two algorithms and write your number sentences.

Choose two:

Algorithm	Visual Example
Area Model	[Draw a rectangle split into parts: 3 × 4 and 0.2 × 4]
Partial Products	3 × 4 = 12, 0.2 × 4 = 0.8 → 12 + 0.8 = 12.8
Lattice Multiplication	Set up lattice for 3.2 × 4
Traditional Algorithm	Line up 3.2, multiply by 4, adjust decimal

✍️ Student explanation:

I chose partial products and area model because they show the decimal clearly. My answer is 12.8. I checked with the stamp game and both algorithms matched.

⚫ Abstract

Number sentence:
3.2 × 4 = 12.8

✅ CONTROL CARD

Answer: 12.8 ounces
Stamp Game Representation: Correctly built and exchanged
Two Algorithms Used: Partial Products & Area Model
Visual Match Confirmed? ✅
Student Reflections: Included
