Children investigate equivalent fractions with concrete material.
They identify and explain that equivalent fractions have the same relationship between the numerator and denominator.
For example, they use a fraction wall to identify that four-eighths and five-tenths are equivalent. They investigate the relationship between the numerator and the denominator in each fraction and explain that four-eighths and five-tenths are equivalent because the numerator is half of the denominator in both fractions, ie 4 is half of 8, and 5 is half of 10.
