Fractions - Equivalence one half and two quarters - Presentation

In a series of engaging activities, students are introduced to the concept of fraction equivalence, particularly focusing on understanding how one half is equivalent to two quarters. The lesson begins with a discussion on the meaning of equivalence and where students might have encountered this term before. They are then guided through a practical exploration using two identical strips of paper, where they fold the strips into halves and quarters to visually compare the sizes and understand the equivalence between one half and two quarters. This hands-on approach helps to solidify the concept of equivalent fractions in a tangible way.

Further activities include shading exercises where students shade one half and two quarters of various shapes to reinforce the idea that these two fractions represent the same portion of a whole. They also work with counters or concrete objects to find one half and two quarters, observing the equivalence in a different context. To delve deeper into reasoning, students are presented with scenarios involving sweets and cubes, prompting them to use critical thinking to demonstrate and explain fraction equivalence. For example, they are challenged to consider who gets more sweets when one child is given half and another two quarters of a jar, leading to the realization that both amounts are the same. The lesson encourages independent thought and concludes with students writing their observations and explanations, further reinforcing their understanding of equivalent fractions.
