Same digit, different value
Reviewed by an experienced teacher. Not yet classroom-trialled.
Prepare to teach
Goal: compare the same nonzero digit in adjacent whole-number places. One place further left gives that same digit ten times the value. This is not a rule for any two different digits.
Entry: in 110 ask for 100 and 10 and how many tens make 100; in 3300 ask for 3000 and 300. Unclear units → Resource 1. Explain comparison language as needed; record help. Keep 440/470 for the later contrast check.
Prepare: solve the examples; an aide rehearses with the teacher. One short bar matches one long-bar part and one interval. Count circled parts/jumps 1–10, naming each value. Ten intervals have eleven ticks. Ask what 10 and 20 mean in 200 = 10 × 20. Each page’s labelled scale is separate.
