Reading and writing numbers (age 10+)
Read, write, and compare decimals to thousandths using base-ten numerals, number names, and expanded form; compare using >, =, < based on place-value meaning

Teaching Table
Set out your lesson
Read and write decimals to thousandths. Use digit values to expand, compare and order them.
Ask what 0.1 and 0.01 mean and which is larger. Expect one tenth and one hundredth; 0.1 is larger. Ask the learner to show that 0.30 and 0.3 have equal value. If this is unclear, revisit the named decimal comparison and thousandths prerequisites before this lesson.
Check readiness directly. Prerequisite availability is not attainment.
Use these linked lessons over several short sessions. Start with the readiness check; if it is not secure, revisit the named prerequisites rather than treating source availability as learner readiness. Use Show, Guided, then Try. Read the active sheet on screen and answer on plain paper or by typing. No printer, cutting, purchase or internet is needed. The adult may read the exact prompt. Record any hints, scribing or calculation help. Oral explanations do not show independent reading or handwriting. Use extra space and time as needed; pause or split the lesson. Keep this adult guide and all keys private. Share only the active learner sheet. Before Try, put Show, Guided work and notes aside. Keep the Try givens available, including a unit table if supplied. Give no answer or target step during the first attempt. If help is needed, give it and mark the attempt supported. Review keys after the attempt. Record the actual response and help; do not invent success or infer mastery from one attempt. These are fictional paper or oral mathematics tasks. No personal information, public sharing, purchase, real transaction, physical experiment or real measurement is required.
Record the actual response and assistance. These tasks do not establish mastery.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
A bounded set of positive decimals to thousandths. Exact canonical examples are teaching models, not independent evidence. Reading aloud, typing and handwriting are separate response modes. The sign-selection sample includes <, > and = with place-value reasons. These finite opportunities do not establish exhaustive three-sign discrimination or mastery.
Record the actual response and assistance. These tasks do not establish mastery.

Check understanding
- Write 347.392 in expanded form: 3×100 + 4×10 + 7×1 + 3×(1/10) + 9×(1/100) + 2×(1/1000)
- Compare 0.372 and 0.38 using place-value reasoning
- Write 'five and sixty-two thousandths' as 5.062
“Can your child read and write decimals like 3.047 or 0.625, say what each digit means (3 ones, 0 tenths, 4 hundredths, 7 thousandths), and put a set of decimals in order?”
