Q1 4.NBT.A.1
In the rocket flight telemetry system, a critical coordinate is recorded as 347,208. What is the value of the digit 7 in this coordinate?
Value of the 7:
7,000 (or 7 thousands)
Misconception: If student writes "7", they confused actual value with the face value of the digit.
Q2 4.NBT.A.2
Write the cargo bay load limit of 502,390 kg in expanded and word form.
Expanded:
500,000 + 2,000 + 300 + 90
Word Form:
Five hundred two thousand,
three hundred ninety
Scoring: Award 0.5 pts for correct expanded form, 0.5 pts for complete word form. Minor spelling is acceptable.
