Unit Fractions: Equal Parts and the Same Whole

Later response 1

Strips N and P are equal-sized wholes. Name each shaded unit fraction and compare them with an explanation.

Strip N: a strip split into 4 equal parts. The leftmost part is shaded. Strip P: a strip split into 8 equal parts. The leftmost part is shaded. The complete strips are the same length.

Unit Fractions: Equal Parts and the Same Whole

Later response 2

Strip Q and Strip R are different-sized wholes. Q has half shaded and R has one quarter shaded. Can the fraction names alone tell which shaded physical strip is longer? Use these drawings to explain what you must check.

Strip Q: a strip split into 2 equal parts. The leftmost part is shaded. Strip R: a strip split into 4 equal parts. The leftmost part is shaded. The complete Strip R is twice as long as the complete Strip Q. The shaded parts are the same length.
