Hint for students
Compare decimals by place value. Add trailing zeros when helpful: 0.8 = 0.80.
Common mix-up
More digits do not automatically mean a larger decimal. Also, the decimal point separates ones from fractional places; it is not itself a place value.
Try it in class or at home
Represent one decimal with a place-value chart, fraction, grid, and number line. Explain why all four representations show the same value.
Teacher prompt
Build 0.4 and 0.35 with a hundred grid or base-ten model. Rename 0.4 as 0.40 and ask students to compare values using place value.
