Objective: To understand the unlike fractions by paper folding and comparing

them.

Things We need: 3 equal strips of paper.

Procedure: (i) Bring the two opposite edges of the first strip. Fold and press it

that a crease is formed. Unfold the paper. The crease has
1
divided the strip into two equal parts, each
2
(ii) Fold the second strip into one half as above. Fold the folded

striponce more so the crease overlaps the opposite edge. The
1
paper is divided into four equal parts each by creases.
