Taught at a 2nd grade level, these 5 slides assist in teaching a lesson on equal shares of shapes. Each slide is accurately alligned and have room for the teacher to write and illustrate as needed.
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
