Model times ten
Write 3.5 on a place value chart and multiply by 10 out loud: "Every digit slides one place to the left." Then do ×100 and ÷10. Kids watch the digits move instead of the decimal point, which is the real idea.
Why it works: showing first, practicing together, then letting kids try alone is the "gradual release" model teachers have relied on for decades (Pearson and Gallagher, 1983).
