Success: read and build a number to three decimal places, including a zero placeholder. Prepare place-value cards or four-column table. (AC9M5N01)
Notice · 2 min. Display 1.235. Ask what the last digit is worth; do not accept “five” without a place.
Model · 4 min. Build 1 + 0.2 + 0.03 + 0.005 in columns. Say “one and two hundred thirty-five thousandths” and “one point two three five”; connect the forms.
Build together · 5 min. Learners show 1.205; ask why the hundredths position is zero. Contrast 1.25 by writing 1.250.
Independent turn · 7 min. Build 2.074 and 0.905, say or label the value of the 7 and 5, and expand one number. Counters, typing or AAC selection allowed.
Explain · 4 min. Pairs compare 1.205 and 1.25: which place first differs? Teacher listens for hundredths 0<5.
Exit · 3 min. “What is the value of 5 in 1.205?” Key: 0.005, five thousandths. Record if learner says five hundredths.
