Long Division Lab: Molecular Split
Master the Formula
Safety Goggles On! In the Long Division Lab, complex chemical compounds (large numbers) must be synthesized into stable elements. This delicate process requires a strict procedure.
This game breaks down the intimidating Long Division algorithm into step-by-step interactions, ensuring children don't get lost in the process.
🧪 The Standard Protocol (DMSB)
To solve $432 \div 12$, we follow a 4-step cycle until nothing remains:
- 1. Divide: How many 12s go into 43? (3).
- 2. Multiply: $3 \times 12 = 36$. Write it underneath.
- 3. Subtract: $43 - 36 = 7$. This is the remainder for this step.
- 4. Bring Down: Drop the next digit (2) to make 72. Repeat!
Lab Certification (Year 6)
Long Division
Divide numbers up to 4 digits by a two-digit whole number using the formal written method of
long division.
Interpreting Remainders
Interpret remainders as whole number remainders, fractions, or by rounding, as appropriate
for the context.
