Fractions - Equivalent Fractions (3) - Presentation

The lesson on Equivalent Fractions is designed to deepen students' understanding of how fractions can represent the same value in different forms. The lesson begins with a discussion prompt, asking students if a fraction can have more than one equivalent and to provide examples. The teaching slides guide students through visual representations and mathematical reasoning to identify and write equivalent fractions. For example, they learn that 1/3 is equivalent to 3/9 and 1/4 is equivalent to 2/8 by multiplying the numerator and denominator by the same number. The lesson includes a variety of activities, such as using paper strips folded into different numbers of equal parts to visually compare fractions and discover equivalences, like how two eighths are the same as one quarter.

Further activities involve using squared paper to draw bars and split them into different numbers of equal parts to find equivalent fractions, such as 3/4 being equivalent to 6/8. A fraction wall is used in another activity to help students visualize and find multiple fractions equivalent to one half, such as 2/4, 3/6, 4/8, and so on. The lesson also challenges students' reasoning skills with tasks that require them to identify mistakes in fraction equivalences, like correcting the misconception that 5/7 is equivalent to 5/14, and to consider fractions that could represent the same area when shaded on paper strips. Independent work encourages students to use the fraction wall to find equivalent fractions for one half, one third, and one quarter, while discussions and manipulatives like Cuisenaire rods or pattern blocks are suggested to explore the patterns between numerators and denominators in equivalent fractions.
