Halves, not halves, fourths, not fourths-Distinguishing halves and fourths based on equal and unequal shares.
Students color one piece of each shape and determine if the shape has equal or unequal shares. They then have to decide if it represents equal halves, unequal halves, equal fourths, or unequal fourths. (Three shapes do not represent any of those options. You can use this as an extension for children who are ready to discuss more than halves and fourths.)
There are three shapes to represent equal halves and three to represent not halves. Although any shape that is not in two equal parts could be representative of “not one half” I instruct the students to choose the shapes that are in two pieces. The same is true for the fourths.
Students cut out the cards at the bottom of the page, sort them into the appropriate rows, and glue them down. The 3 leftovers can be glued to the back of the page.
Note that the rectangle that is cut into four pieces on the diagonals is not cut into equal parts.
