how can an area model be used to represent fractions? try folding paper to show equal parts of a whole. in this square, the green part is one-fourth, because it is one-fourth the area of the whole shape. we can also use area models to explore other big ideas.
How To Add Fractions Uk, each of these shapes represent one-whole. which shape shows one-fourth colored green? i think the first shape shows one-fourth because the part colored, is one-fourth the area of the whole.
yes. even though the parts are not equal, the green part is still one-fourth the area of the whole shape. how would you describe the green part of the second shape? well i see two colored parts, but togetheri know they are one-fourth the area of the whole. correct! now look at the last shape. does that show one-fourth? no, because although it is divided into four parts, the green part is not one-fourth the area of the whole. that's right!
