Confirm-and-skip candidate: Grade 4 Math 10–11 overlap this anchor. If the baseline and a second-day check are secure, save the evidence and go straight to Checkout Champion or the first stretch lab.
Success criteria
- I can name and value digits through thousandths.
- I can compare and round without treating decimal digits as whole numbers.
- I can explain why moving one place changes value by a factor of ten.
Learn and explain
In 4.307, the digits mean 4 ones, 3 tenths, 0 hundredths, and 7 thousandths. The 7 is worth 0.007. Moving a digit one place left makes its value ten times as large; moving right makes it one tenth as large.
Explain why 6.09 can be written as 6.090 without changing its value.
Independent practice
How many thousandths are in 4.307?
Which number is greater?
Write 6.09 as 6.090, then compare thousandths.
Round 8.764 to the nearest tenth.
Transfer
A measurement app shows 2.500 m; a label shows 2.5 m. Decide whether the objects have equal lengths, then explain what the extra zeros communicate.
Delayed check
After at least two days, order 0.509, 0.59, and 0.095 and round each to the nearest tenth without reopening this page.
Evidence and next step
Save the ordered-number work and explanation at jeremy/portfolio/math/unit-1/place-value-skip-check.md.
- Independent on two days + explanation + transfer → mark confirmed and skipped/secure; Unit 2 work or stretch may open.
- One place-value error → practise only that place, then retry in 48 hours.
- Several errors → complete the full anchor before Lesson 2.
